It has a trick up its sleeve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I\u2019m not one to preference good looks over serious performance. But this is getting to be one ugly gun. A couple of years ago, I needed a break action shotgun for a review I was planning. I\u2019d lined up some multicaliber 12 gauge barrel inserts that promised to turn ol\u2019 Betsy (or whatever you\u2019ve named your break-action clunker) into a versatile survival piece capable of firing anything from a .308 to a .22 short. So I picked up this beauty, a rusted out Ithaca Model 66. The old girl locks up tight, and has a clean, shiny bore. She wasn\u2019t much to look at, but she shot straight. And that\u2019s all I needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If she wasn\u2019t much to look at before, I surely didn\u2019t help make things better. I tore the gun down, completely, and cleaned everything up. I sanded out all off all of the rust. I cut the barrel down to 18.5 inches. I even Duracoated the whole thing, just to see how well the finish worked. It was all well and good, but missing a front sight. Enter the Truglo TG-H3.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The TG-H3 looks a bit out of place on this beastly shotgun. If I were more vain, it wouldn\u2019t be my first choice for a lever action. But I wasn\u2019t concerned about the aesthetic. If the barrel inserts do come in for review, I\u2019ll need a sight. And the TG-H3 is a serious sight. It is long, and wide. It installs on a 12 gauge barrel fairly easily. There are two holes that need to be drilled into the top of the barrel, and it may be best to have a gunsmith do it, but it can be done at home.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/09\/duracoat16.jpg\" alt=\"What would posses someone to paint Duacoat an entire shotgun in tan? Beats me, and I&#x27;m the one that did it.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">What would possess someone to Duracoat an entire lever action shotgun in tan? Beats me, and I\u2019m the one that did it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The real appeal of the sight, though, is the fat glowing tube. As we\u2019re talking shotguns here, a wide front sight isn\u2019t a detriment. At seven yards, the glowing dot is still smaller than a birdshot pattern and buckshot pattern. That pretty much covers the defensive end fairly well.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-15-400x266.jpg\" alt=\"The  TG-H3 glows, even in full darkness, thanks to the tritium in the tube.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The TG-H3 glows, even in full darkness, thanks to the tritium in the tube.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The insert glows well, thanks to the combination of tritium and fiber optic. The dot is visible even in full darkness. Not that I\u2019d advise shooting anything in full darkness, but it is nice to think you could. And because the business end of the sight\u2019s frame is solid, the glow is shielded from anyone in front of the gun. The side view is a different story, as the frame is cut to allow ample light transmission. But the tube isn\u2019t visible from the side in the dark, only from the shooter\u2019s perspective. Truglo calls this TFO (Tritium Fiber Optic).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All told, I\u2019m thrilled with the sight. I moved recently, and threw the gun, as you see it here, into the moving truck in a rather unceremonious fashion. The ride was long, and somewhat brutal for the finish on the Ithaca. Yet the sight remained in place, intact, just as I\u2019d suspected. It can take a beating. And I\u2019m hoping it can dish one out, too. I\u2019m looking for a rear sight now, one that will compliment this giant front sight, and one that will make this ridiculous shotgun look even more ludicrous.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And I\u2019m still waiting for the inserts. That\u2019s the reason for this gun\u2019s continued existence. When they arrive, the TG-H3 will get a full on workout, and I\u2019ll post a follow up to this one. <\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-3-400x266.jpg\" alt=\"The dot on the  TG-H3 is wide, and the base of the sight is as wide as some rear sights, but it is ideal for a scatter-gun.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The dot on the TG-H3 is wide, and the base of the sight is as wide as some rear sights, but it is ideal for a scatter-gun.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-11-400x266.jpg\" alt=\"The frame itself has been milled and contoured to protect the insert and gather light.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The frame itself has been milled and contoured to protect the insert and gather light.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-4-400x266.jpg\" alt=\"The tube slides into the milled frame, which pins in place on the barrel.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The tube slides into the milled frame, which pins in place on the barrel.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-6-400x266.jpg\" alt=\"This is all you need to hold everything in place.\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This is all you need to hold everything in place.

If I were more vain, it wouldn't be my first choice for a lever action anything. But I wasn't concerned about the look. The Truglo TG-H3 is a bad-ass sight. It is long, and wide. It installs on a 12 gauge barrel fairly easily, and it combines Tritium and fiber optic technologies for one radiant sight.","og_url":"https:\/\/gunsamerica.com\/digest\/truglo\/","og_site_name":"Gun Reviews and News | GunsAmerica.com\/Digest","article_publisher":"https:\/\/www.facebook.com\/gunsamerica","article_published_time":"2014-09-07T18:08:39+00:00","article_modified_time":"2026-10-19T00:17:56+00:00","og_image":[{"width":1200,"height":799,"url":"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-16.jpg","type":"image\/jpeg"}],"author":"Dave Higginbotham","twitter_card":"summary_large_image","twitter_creator":"@gunsamerica","twitter_site":"@gunsamerica","twitter_misc":{"Written by":"Dave Higginbotham","Est. reading time":"6 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"Article","@id":"https:\/\/gunsamerica.com\/digest\/truglo\/#article","isPartOf":{"@id":"https:\/\/gunsamerica.com\/digest\/truglo\/"},"author":{"name":"Dave Higginbotham","@id":"https:\/\/gunsamerica.com\/digest\/#\/schema\/person\/4297e0be17b42d4988e700442f99cf5f"},"headline":"Truglo TG-H3 Review: Tritium Fiber Optic Shotgun Sight","datePublished":"2014-09-07T18:08:39+00:00","dateModified":"2026-10-19T00:17:56+00:00","mainEntityOfPage":{"@id":"https:\/\/gunsamerica.com\/digest\/truglo\/"},"wordCount":1140,"commentCount":4,"publisher":{"@id":"https:\/\/gunsamerica.com\/digest\/#organization"},"image":{"@id":"https:\/\/gunsamerica.com\/digest\/truglo\/#primaryimage"},"thumbnailUrl":"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-16.jpg","keywords":["Accessories"],"articleSection":["#HUNTGear","Accessories Misc.","David Higginbotham","HUNT365"],"inLanguage":"en-US","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https:\/\/gunsamerica.com\/digest\/truglo\/#respond"]}],"accessibilityFeature":["tableOfContents"]},{"@type":"WebPage","@id":"https:\/\/gunsamerica.com\/digest\/truglo\/","url":"https:\/\/gunsamerica.com\/digest\/truglo\/","name":"Truglo TG-H3 Review: Tritium Fiber Optic Shotgun Sight","isPartOf":{"@id":"https:\/\/gunsamerica.com\/digest\/#website"},"primaryImageOfPage":{"@id":"https:\/\/gunsamerica.com\/digest\/truglo\/#primaryimage"},"image":{"@id":"https:\/\/gunsamerica.com\/digest\/truglo\/#primaryimage"},"thumbnailUrl":"https:\/\/gunsamerica.com\/digest\/wp-content\/uploads\/2014\/08\/Truglo-16.jpg","datePublished":"2014-09-07T18:08:39+00:00","dateModified":"2026-10-19T00:17:56+00:00","description":"Truglo TG-H3 review: a tritium fiber optic front sight for 12 gauge barrels.
