It\u2019s ambidextrous &#8211; there are slide lock \/ release levers on both sides. The magazine release operates on one side at a time but is reversible. The takedown lever is on the left side\u00a0only. Of course, there\u2019s no compelling reason for that to be ambidextrous as it\u2019s not something you need to operate while shooting.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_54316\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54316\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54316\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-20-400x300.jpg\" alt=\"The M&amp;P 45 ate everything I fed it, including a healthy diet of lotsa these lead hand loads.\" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-20-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-20-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-20.jpg 1000w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-54316\" class=\"wp-caption-text\">The M&amp;P 45 ate everything I fed it, including a healthy diet of lotsa these lead hand loads.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_54317\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54317\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54317\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-16-400x300.jpg\" alt=\"The threaded barrel is exactly 1\/2-inch longer than the standard and comes with a thread protector. \" width=\"400\" height=\"300\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-16-400x300.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-16-150x113.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-16.jpg 1000w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-54317\" class=\"wp-caption-text\">The threaded barrel is exactly 1\/2-inch longer than the standard and comes with a thread protector.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>As of now, there\u2019s not an option for a manual safety as with other M&amp;P models.

The full-size footprint is fine with me as you\u2019re gonna end up with a huge pistol anyway when you mount a .45 caliber suppressor on it. One more thing to note. We\u2019re covering the .45ACP model here, but Smith &amp; Wesson also offers the M&amp;P 9mm Threaded Kit. It\u2019s virtually identical to the .45 big brother we\u2019ll discuss here except it\u2019s a tad less expensive and has \u00bc-inch shorter barrels.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_54318\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54318\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54318\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-12-400x300.jpg\" alt=\"The controls are simple - takedown lever, slide lock and magazine release.

Both slide and barrel are treated with a black corrosion-resistant finish. The slide has the characteristic M&amp;P scallop-pattern slide serrations at the rear and a smaller set forward for press checks. The left side of the slide is fairly clean, having only an engraved Smith &amp; Wesson and M&amp;P45 logos. The right side also has an engraved Smith &amp; Wesson mark. Fouling up the otherwise very attractive slide is a caution warning in small white letters. \u201cCaution: Capable of firing with magazine removed.\u201d Because lawyers. Uggh. Along the top, you\u2019ll note a visual cue that this is a .45 as the caliber is engraved in the top of the barrel chamber. A small hole above the breech face allows a visual check to see if anything is in the chamber.<\/p>\n<div id=\"attachment_54313\" style=\"width: 1010px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54313\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"wp-image-54313 size-full\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-5.jpg\" alt=\"This gun is meant to be configured like this.

I mounted three different silencers on this pistol during testing, a SilencerCo Osprey 45, an SWR Octane 45, and an Advanced Armament Corporation TiRant 45 Modular. With all three, the sights were obscured by the suppressor bodies and I had to \u201cshoot through\u201d the suppressor. This isn\u2019t really as big a deal as it may sound. When you shoot with both eyes open, your brain will transpose the sights and target anyway, but I would prefer to have suppressor-height sights come standard on this model.

When you drop the magazine (and fully unload the gun!), you\u2019ll see a protrusion on the back of the magazine well that looks almost like a partial magazine well. Rotate this 90 degrees in either direction and it will pull completely out of the grip in the same direction that the magazine drops. As a side note, this tool can also be used to disengage the sear when you take down the pistol for cleaning, so you don\u2019t have to pull the trigger. You might need to apply a bit of force to remove the pin tool &#8211; my sample gun had a tight fit. Once this pin is removed, you can rock the existing backstrap insert out.

Why? Mainly because it\u2019s a lot more fun to shoot with a suppressor!<\/p>\n<p>I\u2019ve always like the way the M&amp;P handles. I tend to prefer the more rounded grip profile of an M&amp;P as compared to a Glock. For me, it just fits the hand better and, as a result, is easier to control. The 18-degree grip angle also points naturally for me. If I close my eyes and raise the gun, I find the front and rear sight already in the same plane and generally close to on target. So, again, for me, the M&amp;P is consistent with my natural point of aim. Again, for me, guns like the Glock, with it\u2019s more aggressive grip angle, tend to point high when I thrust the gun forward without thinking about it. Of course, this is an individual \u201cfit\u201d thing, so your mileage may, and probably will, vary. I kept repeating \u201cfor me\u201d because there is no right or wrong grip angle &#8211; that\u2019s something you have to try for yourself with a few different guns.<\/p>\n<div id=\"attachment_54314\" style=\"width: 1010px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54314\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-full wp-image-54314\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-1.jpg\" alt=\"A movie prop from Mad Max?

Over a few outings, I also shot several hundred of my 185-grain lead semi-wadcutter hand loads. The M&amp;P 45 didn&#8217;t have any trouble feeding those either.<\/p>\n<p>I did my accuracy testing at an outdoor range late one afternoon, so with the onset of twilight conditions I figured it was the perfect time to test this out with a laser. Also, as the factory sights are obstructed by the suppressor, the laser allowed me to get an accurate sight picture 25 yards down range. Most Lasergrips and rail-mounted lasers will clear the suppressor body and provide a pretty good alternate sighting method. I used the Crimson Trace Rail Master Pro, which actually houses both a red laser and 100-lumen light. Since the operation mode is configurable, I disabled the light and used the laser only mode for sighting purposes. This rail mounted laser had no trouble clearing the body of a SilencerCo Osprey 45 suppressor, even though its oblong shape places more of the silencer body below the bore line.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_54334\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54334\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54334\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-4-400x256.jpg\" alt=\"So i could get an unobstructed sight picture, I mounted this Crimson Trace Rail Master Pro for accuracy testing.\" width=\"400\" height=\"256\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-4-400x256.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-4-150x96.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-4.jpg 1000w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-54334\" class=\"wp-caption-text\">So i could get an unobstructed sight picture, I mounted this Crimson Trace Rail Master Pro for accuracy testing.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_54335\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54335\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54335\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-24-400x256.jpg\" alt=\"Other than this &quot;helpful&quot; warning printed on the slide, the M&amp;P is a very attractive handgun.

The chamber area and top of the magazine tend to collect grime a lot faster so you should plan on more frequent cleaning to keep things running.<\/p>\n<p>[one_half]<\/p>\n<div id=\"attachment_54336\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54336\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54336\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-AAC-TiRant-45-1-400x267.jpg\" alt=\"I shot the M&amp;P 45 Threaded with a broad assortment of .45 ACP ammo ranging from 185-grain to 230-grain loads. \" width=\"400\" height=\"267\" srcset=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-AAC-TiRant-45-1-400x267.jpg 400w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-AAC-TiRant-45-1-150x100.jpg 150w, https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-AAC-TiRant-45-1.jpg 1000w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><p id=\"caption-attachment-54336\" class=\"wp-caption-text\">I shot the M&amp;P 45 Threaded with a broad assortment of .45 ACP ammo ranging from 185-grain to 230-grain loads.<\/p><\/div>\n<p>[\/one_half]<\/p>\n<p>[one_half_last]<\/p>\n<div id=\"attachment_54337\" style=\"width: 410px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-54337\" title=\"Gun Review: Smith &amp; Wesson M&amp;P 45 Threaded\" class=\"size-medium wp-image-54337\" src=\"https:\/\/www.gunsamerica.com\/blog\/wp-content\/uploads\/2016\/03\/Smith-Wesson-MP45-Threaded-Kit-6-400x196.jpg\" alt=\"The M&amp;P 45 Threaded shown here with a SilencerCo Osprey 45.

The flat-sided suppressor paired well with the M&amp;P, adding nothing to the width of the whole package.<\/p><\/div>\n<p>[\/one_half_last]<\/p>\n<p>If I decide to send a check rather than return this loaner gun, I\u2019ll almost certainly get a set of suppressor height sights for it. While you can achieve \u201cplenty good enough\u201d practical accuracy by \u201cshooting through the suppressor\u201d with the existing sights, I\u2019d want the option of more precise sighting. I would also want at least the taller front sight to be Tritium powered. The M&amp;P 45 Threaded would make a great nightstand gun and keeping a suppressor on it is not a bad idea. If you ever do need to shoot it indoors, you\u2019ll probably appreciate the lack of muzzle flash and not having a deafening blast amplified by interior walls.<\/p>\n<h2>Closing Thoughts<\/h2>\n<p>I enjoyed shooting this gun, partly because I\u2019ve always been partial to M&amp;Ps, but also because I like the balance of size, handling, and capacity. By keeping the double stack .45 ACP magazine capacity to 10, Smith &amp; Wesson was able to keep the overall size of this gun within manageable range. You can absolutely carry it. With the smallest grip panel installed, those with hands smaller than KoKo the gorilla can handle it with ease. I wear medium to large gloves depending, so my hands aren\u2019t huge. I can easily reach my index finger far enough to engage the trigger with the first joint if I want, so a \u201cmiddle of the pad\u201d reach is possible with any of the three grip panels installed.<\/p>\n<p>The two barrel approach might come in handy if you choose to carry this one and use it suppressed. While you can certainly carry the gun with the threaded barrel installed, that configuration adds a \u00bd inch to overall length, and you have to worry about making sure the thread protector stays put. Certainly it\u2019s easy enough just to swap out the barrel, and you\u2019re good to go.<\/p>\n<h2>Factory Specs<\/h2>\n<p>SKU: 150923<br \/>\nModel: M&amp;P\u00ae45 Threaded Barrel Kit<br \/>\nFrame Size: Full Size<br \/>\nCaliber: .45 ACP<br \/>\nAction: Striker Fire Action<br \/>\nCapacity: 10+1 Rounds<br \/>\nBarrel Length: 4.5\u201d (11.4 cm)<br \/>\nFront Sight: White Dot<br \/>\nRear Sight: Low Profile Carry<br \/>\nOverall Length: 8.05\u201d (20.4 cm)<br \/>\nOverall Height: 5.5\u201d (14.0 cm)<br \/>\nOverall Width: 1.2\u201d (3.0 cm)<br \/>\nGrip: 3 Polymer, Palmswell Grip Sizes<br \/>\nWeight: 29.6 oz.
