The SIG P938 – SIG’s Forgotten Gem

in Gun Reviews, Handguns

Estimated reading time: 0 minutes

I used to teach some basic firearm safety classes, primarily focused on pistols. After teaching for a few years, I was able to typically tell if someone was going to have a good time on the range depending on the gun they brought. Pocket .380s, micro 9s, and snub nose revolvers were almost always a crapshoot for new shooters. When I first saw the SIG P938 in a student’s hands, I thought for sure they were going to have a bad time and my S&W 22A was going to be broken out.

The SIG P938 defied my expectations and made a fantastic first impression. It is an accurate, easy-to-shoot, and reliable handgun.

Imagine my surprise when my student performed admirably with the gun. This was the first time she’d ever fired her P938 and one of the few times she had ever fired a pistol. The little gun proved to be controllable, accurate, and easy to handle for an amateur while being small enough to pocket carry. That left an impression on me, and when I saw a used P938 for a very low price point I snatched it up. 

The SIG P938 – A Forgotten Gem  

A big reason I was able to purchase this P938 for such a deal was that guns like this are often rejected in the face of guns like the SIG P365. The humble single-stack 9mm has given up the ghost to micro compacts. Guns like the P938 just aren’t wanted that much these days. The P938 was never a cheap gun; in fact, it was one of the costlier single-stack 9mms, but lower demand means lower prices.

In the modern era, seven rounds doesn’t seem like a lot, but it’s likely more than enough for the typical self-defense encounter.

This begs the question, is the SIG P938 still a capable defensive weapon? The obvious answer is yes. It might not hold ten rounds of 9mm, but seven, plus one in the chamber, hardly puts it at much of a disadvantage. We are a consumerist culture, and I won’t lie and say I don’t mind getting the most I can out of a gun, but that doesn’t automatically make everything that came before the gun obsolete.

The P938 offers a single action only, hammer-fired, subcompact, single stack 9mm pistol.

The SIG P938 is an interesting firearm. In the modern era, everything is a polymer-frame, striker-fired pistol. Even when the SIG P938 was released, it was a different type of firearm. SIG released the gun in 2011, and that was the era when SIG still primarily made hammer-fired guns. 

A 1911 – Kind Of 

It’s not a 1911, but anyone familiar with the 1911 platform would feel right at home with the SIG P938. There is no barrel bushing, and they ’86ed the grip safety. It’s 1911-inspired and offers a micro-sized 1911 for concealed carry. The SIG P938 features a hammer-fired, single-action-only design.

hammer and frame safety
The single-action design with the 1911-like safety certainly draws inspiration from the John Browning design.

The weapon also wears a frame safety that’s easy to engage with the thumb. The slide release is also very 1911-like; the magazine is a single stack, and the frame and shape of the gun all scream 1911. The SIG P938 features nice big sights that are easy to see and far from what we typically expect from a small pistol. 

The grips vary quite a bit. My model has these Hogue-style wrap-around rubber grips, and I’m not a fan. The only upgrade I plan to make to this gun is just switching the wrap-around rubber grips for a more traditional set of grip panels. The wrap-around rubber grips just kill the sleek and slim 1911-style grip. 

Grip on 938
Notice how thick the grip is. I’mma ditch those wrap-around grips soon.

The 1911 has always been beloved for its ergonomics, and it’s not very different here. The safety is somewhat small, but it’s ambidextrous, and your thumb can find the shelf without difficulty. A thumb’s forward grip doesn’t pin down the slide release and is big enough to hit with your thumb while reloading. 

One reason my student liked this gun all those years ago was how easily she could work the action. If she cocked the hammer, she could easily easily manipulate the slide. The slide glides rearward easily with the hammer down and isn’t tough with the hammer in the closed position. 

To The Range 

Operating the slide is great, but what about recoil? Small guns tend to be snappy, and snappy guns aren’t always fun. The SIG P938 differs from most small handguns by being all metal. All that metal gives us weight, and that weight means the gun weighs a solid pound. It’s 16 ounces of metal, and that helps, as does properly weighted springs and smart design.

The P938 is a handy little gun. It’s easy to shoot with low recoil.

That all seems to be apparent with the P938. It’s surprisingly not snappy. I shoot mostly 115-grain ammo, but to test the gun, I tossed in some 124-grain NATO ammo. While the recoil was noticeable, it wasn’t hard to control or what I’d call snappy. It almost handles more like a firearm that’s Glock 19-sized. Another big reason why the gun feels so easy to control is our ability to choke up nice and high on the gun. 

Even with my hand choked up nice and high on the gun, it’s not getting bit by the slide. Small guns like to bite the hell out of my hand, but that’s not a problem with this gun. It’s soft and easy to shoot, and I can happily suggest it to shooters with poor hand strength who are seeking a compact gun that’s light on recoil and easy to operate.

Like most SIGs, there are tons of colors and varied configurations. The P938 has something for everyone.

You can blast through seven or eight rounds quickly while keeping the gun on target. I could shoot a three-second Bill Drill with the P938. Admittedly I didn’t make the tightest group. I’m using the entire A zone of the USPSA target to catch rounds, but they were in the A-zone so it counts. 

Accuracy and The P938 

The big sights help with that low-fire accuracy. A lot of accuracy is tied to a good grip, and the grip on the gun is fine but not excellent. The magazine extension helps prevent a hanging pinky, but the rubber grips suck. I can hold onto the gun just fine, but it gives you that short grip you expect from a gun this size. 

At 25 yards, I can hit an ISPC steel target with ease. I can just hear that ding over and over again. At 15 yards I can put all seven rounds into the 9 and 10 ring of a B8 target routinely. The P938’s big sights are also easy to see and find when the gun is drawn and presented. 

SIG P938 controls
The controls are very 1911-like and super easy to access and utilize.

With a good presentation, the sights align just right for quick and accurate shots after the draw. The big front sight is easy to track for repeatable accuracy. The light single-action-only trigger is exceptional. It delivers on the M1911 reputation with a light trigger pull and crisp reset.

The P938 is from SIG’s hammer-fired era, and it shows. It’s an interesting mix of features that makes it a fantastic little handgun.

One ergonomic performance problem came down to reloads. My pinky pins the magazine in when I hit the magazine release. This necessitates a grip-and-rip approach to reloads or a fancy reload. A fancy reload is when I put my pinky up to let the magazine free. The magazine drops, but I’m abandoning my firing grip to do so. 

A Working Option 

The P938 chewed through everything I put through it. I ran into no reliability issues, even when the magazines fell into the sand of my range. It’s a reliable, defensive-worthy pistol. The P938 might not be the cool kid on the concealed carry block, but it’s still pretty dang cool.

Guns like this are becoming cheaper and cheaper due to a lack of demand, if you shop around it might be one helluva bargain.

An all-metal, single-action-only, hammer-fired gun that’s small enough to be pocket-carried is pretty neat. It’s certainly different from the usual fair of firearms currently on the market. I like different things, and the P938 checks that different box.

    Great pistol for pocket carry. Ambi safety and fiberoptic sights make a very good pistol.

    I have one of these with the G10 grips. After doing a trigger job with a replacement trigger and hammer spring (aftermarket), mine is a tack driver. Slips right into a pocket, is reliable as all get out, and again, I can hit what I want with it. Perfect for running to the store or working outside around the house. We have some snakes around and this little guy can take their head off, and has accounted for four snakes so far…

    The Sig P238 (in .380) made it onto California’s roster before the microstamp law went into effect, but the P938 came out just a little bit too late. And both were on the pricey side. It is mechanically a copy of the Colt Mustang, the patent on which had expired, and which was itself a version of a Spanish pistol. Kimber made a similar pistol that met with severe reliability issues. And Colt eventually joined the party with a polymer framed redux. So these were never available to me, though admittedly I lusted after the P938.Make no mistake; it is not a 1911. The trigger hangs from directly above it in the frame. There is no frame safety. The take down is dissimilar.

    If you want a mini-1911, Springfield makes the EMP in 9 mm and .40. It is pricey. It is 27 oz. But it is a well engineered mini-1911. It now comes in two barrel lengths. I have one. It is utterly reliable with HPs, and soft shooting with 124 gr 9 mm rounds. It has a full sized grip and ambi safeties. It came with night sights. I got mine in a package with a range bag and ten mags. On sale. (Lucky me.) Because of its weight, it is easily controllable and accurate. It conceals well in an OWB or IWB holster, but it is too large for pocket carry. So I am not too upset that I never had a chance at the Sig.

    Great pistol! I carry locked n locked in a cross draw driving holster with a safety strap between the hammer and frame.

    • Mike in a Truck March 11, 2025, 10:38 am

      That should be Cocked and Locked!

    I have an SAS that I use for pocket carry. I ditched the wood panel grips for the Hogue wrap-around rubber grips. I don’t have the biggest hands, but have to wear XXL sized gloves and find that the Hogue grips help me maintain a better grip and further help manage recoil. I also installed the Crusader trigger and return spring from Galloway Precision and it’s the best $56.50 you can spend as it drops the pull wieght down to around 5lbs. which makes it a much more shootable gun.

    Looking closer at your photo array, I see that you’re running an extended Springfield Armory 911 9mm magazine in your P938 … Nice to know that there’s cross compatability here too, just like in the full size 1911 platform pistols.

    We have seen quite a few at our range.
    The thumb safety was easy to disengage. The problem was to put it back on safe.
    Almost all were impossible to reapply the safety with your dominant hand thumb,
    We had to teach the students to reapply the safety with their support hand thumb.
    This wasn’t just a “one of” problem either.

    “I’mma ditch those wrap-around grips soon.” ???

    Well, youado that.

    I really like my 938. It’s my gun when I can’t carry my usual gun.

  • Mysterious Traveler March 10, 2025, 11:41 am

    And let’s not forget about the SIG P238 – same gun in 380acp. Even less “snappy”!

  • Rusty March 10, 2025, 9:49 am

    I got a couple, but would not recommend carrying them cocked n locked for concealed carry; if you do strenuous work. Mostly I carry on the farm, for coyotes, snakes, etc. I always carried it with hammer back, safety engaged, on an empty chamber. (When in an urban jungle, a round is chambered!!). Anyways, carrying it owb, and iwb, I had several times found it safety off, hammer down at the end of the day. The lack of a grip safety is a serious issue with a single action auto used for CC. I have procured a 365 SAS, which being striker fired, I feel is a bit safer option for loaded carry. Sucks, I love the 938 (I used to carry a Colt Pocket Nine until I started seeing the price of em on GB, retired it to the investment safe when I found the 938!!)

    I don’t call $750 a thrifty priced gun.

    • F Starrucca March 10, 2025, 2:43 pm

      I see LNIB used ones here for $400-$450. Easily carried they are worth it
