The SIG P238 pistol is a single-action, semi-automatic pistol chambered for the .380 ACP cartridge. The pistol is considered to be very similar to the workings of a 1911 pistol and is said to have borrowed heavily from the design of the Colt Mustang pistol. Most likely, SIG SAUER purchased the rights to manufacture the Mustang from Colt, though under their own label: the P238.
The P238 was introduced by SIG SAUER at the 2009 SHOT Show in Orlando, Florida. At that time, there were few quality .380 ACP pistols on the market, but the 2008 introduction of the Ruger LCP proved there was an untapped market demand for them. Unlike other manufacturers who were mostly bringing DAO polymer guns to the .308 ACP pocket gun market, SIG SAUER went with a high-quality gun on a metal frame.
The SIG P238 has an anodized aluminum frame and a stainless steel barrel and slide. The pistols are single action guns that have a frame mounted safety. P238 handguns also have a trigger bar disconnect safety, an automatic firing pin block and a hammer safety intercept notch to enhance the pistol’s overall safety.
First P238 Pistols
In the first year of production, SIG only offered two variations of the P238: a standard black finish and a two-tone finish. The basic model was called the “Nitron,” which is the name of the special corrosion-resistant finish that gave the gun it’s black appearance. The Nitron was available with standard SIG “contrast” sights or night sights.
The two-tone model had a black frame with a stainless slide, slide stop, hammer and safety. The P238 grips were a stainless steel (silver) color. Both the original Nitron and the two tone models are still available from SIG SAUER.
The SIG P238 saw exceptional sales in it’s initial year, and sales of the gun have continued to be very positive. Since being introduced, SIG SAUER added numerous variations to the P238 line including various finishes, different grips and a variety of custom etchings.
At the 2010 SHOT Show, SIG SAUER introduced five new models of P238: the Rosewood, Blackwood, Rainbow Titanium, Equinox and the Tactical Laser. All five of these models remain in the current line-up.
The Rosewood is essentially the same as the Nitron model, except that it has the far more attractive rosewood grips. Likewise, the Blackwood model is the same as the two-tone model, except with blackwood grips. The other models were more than just grip changes.
The Rainbow Titanium P238 has an amazing multi-hue finish applied to the slide and other external parts. As the gun is turned, light reflects off of it in various colors, giving it a brilliance unlike any other in the SIG SAUER line. The frame is black Nitron and night sights are standard.
The Rainbow was formerly introduced at the 2010 SHOT Show, which was in January of ’10. However, the company had quietly released the gun in October of 2009.
The P238 Equinox was designed by the SIG SAUER Custom Shop, and features a number of things that make it unique in the line. First off, the front sight is a TRUGLO sight that combines tritium (night sight) with a fiber optic pipe, which gives incredible brightness in daylight and reduced lighting conditions. The slide and frame are finished in black Nitron, but the slide has a two-tone appearance as the high points have been brushed to a natural color. The slide stop, magazine release and the safety are nickel.
In 2010, one model of P238 was released with red laser: the SIG P238 Tactical Laser. The Tactical Laser model uses a unit that mounts to the front of the trigger guard, similar to the Crimson Trace Laserguard. The activation button is on the side of the unit. This pistol is otherwise almost identical to the two tone P238. The only other change is the grips. When originally released, the pistol had grip panels that were also two-toned. Current versions of this P238 have simple, black grips.
Introduced in 2010, but after the SHOT Show, was the SIG P238 SAS. The SAS has the same general design characteristics as other SIG SAUER handguns in the SAS line. The idea behind the SAS series is to remove all sharp edges (aka dehorning) so that nothing interferes with a draw when being carried for self defense.
Also introduced in 2010 was the P238 HD. HD stands for heavy duty. This model is the only P238 that has a stainless steel frame. All other P238 handguns have an aluminum frame. The HD also has G10 grips.
SIG later introduced the P238 HDW. This variation uses the same stainless steel frame as the HD, but features a set of rosewood grips instead of the G10 grips.
The SIG P238 Extreme was the only new pistol in this line announced at the 2011 SHOT Show. The Extreme was Nitron-finished and added numerous features the the pistol. The most obvious upgrade to the P238 Extreme was the addition of the Hogue Piranha grips made from G10. The grips have a unique color pattern and a fairly aggressive texture, allowing a better grip on the small gun.
The P238 Extreme also comes with an extended magazine using an X-Grip extension. This increased round capacity from six to seven rounds. The X-grip extension also gives the shooter a little more pistol to hang on to when shooting. A flush-fitting six-round magazine also comes with the gun.
The final new feature to the Extreme was the addition of serrations on the front of the slide (forward of the ejection port).
At the 2012 SHOT Show, several new models were introduced, but the most significant change was the addition of ambidextrous safeties to a wide variety of the P238 models. Prior to this, ambi safeties were purely custom work on the handguns. Ambidextrous safeties are now offered as an option on many of the P238 pistols, while all of them can be retrofitted at the SIG SAUER Custom Shop. A retrofit includes the replacement of the grips to accommodate the new hardware.
Three new models were introduced at the Show: the Scorpion, the Black Diamond and the Desert.
The SIG P238 Scorpion follows the design cues from the company’s other pistols with the Scorpion finishing. The P238 Scorpion has a custom flat dark earth (FDE) finish and Hogue Piranha grips. The grips are made of G10 and have a unique, multi-colored pattern. The safety, slide stop, trigger and hammer are all a flat black. An ambidextrous safety is standard on the Scorpion.
The P238 Black Diamond is very similar to the original Nitron P238. This pistol has a diamond plate finish on the slide, giving the gun its name and distinctive appearance. The gun also has plain black grips. The Black Diamond can be purchased with the original manual safety or with the new ambidextrous safety.
The SIG SAUER P238 Desert pistol is a two-tone tan gun with a light tan frame and a darker brown slide. SIG describes the coloration as a “…two-tone Flat Dark Earth finish…” The pistol’s trigger, safety, hammer and slide stop are all finished in flat black.
The P238 Desert has a rubber Hogue grip that wraps around the front of the grip frame. The Desert can be had with the ambidextrous or right-side-only manual safety.
Another change in 2012 was that SIG SAUER now makes night sights standard on all P238 pistols.
Not shown at the SHOT Show was the P238 Lady. The Lady is definitely a different looking pistol than the others in the line. The frame is finished in red Cerakote, while the black slide is emblazoned with gold scrollwork and a flower inlay.
At the 2013 SHOT Show, SIG Sauer showed several new P238 models including the P238 Tribal. The new Tribal has a black frame and natural stainless steel slide. The wood grips feature an engraved tribal symbol. The same symbol is repeated on top of and on the sides of the slide.
Limited Runs & Discontinued Models
In addition to the standard variations, there have been some limited production runs including models commemorating the US Marine Corps, the Liberty Bell and the Gadsden Flag. Here is information on a few of these.
The P238 Liberty is a Rosewood model with a 24k gold inlay of the Liberty Bell on the top of the slide. The bell is between the rear sight and the ejection port. On the right side of the slide, the words “We The People” is also printed in gold.
The Gambler is similar to the Liberty model above. It is also a Rosewood model, but has a hand of playing cards on top of the slide where the Liberty Bell would be on the other model. The cards? The dead man’s hand of course: a pair of aces and eights. That is the same hand that “Wild Bill” Hickok supposedly had when he was killed in 1876. On the right side of the frame are the words “The Gambler.”
The Gadsden model of P238 was shipped from SIG SAUER with the words “Don’t Tread On Me” printed on the slide. On top of the frame was the famous coiled snake found on the Gadsden flag. SIG also made a P226 with the same theme.
SIG also produced a Copperhead version of the P238. The Copperhead did not appear to have any relation to the Gadsden model, and the Copperhead trademark was licensed by SIG SAUER from Crosman, the airgun company. The Copperhead did not last long on the market. It featured a copperhead snake picture on the top of the slide and the word “Copperhead” in script on the right-hand side of the frame.
The US Marine Corps edition was another Rosewood model with gold inlay. On this gun, the traditional USMC bulldog was on the slide with the words “Semper Fi” on the right side of the slide. SIG sold this model alone or with a commemorative knife.

The stay open gun is fixed. After 2 more boxes of ammo and one last check by the smith, it has stopped doing it unless it gets hot. If I shoot it rapidly until it gets very hot it will still do it now and then. I can accept that.
I am going to run another few boxes through it just to make sure and to get a little more wear on it, then phase it in as my pocket carry gun if it continues to be reliable.
I may check back in on the half-cocked one, but if it keeps doing it I will have the smith do his thing to it and its not too useful to keep saying “he polished something or other”, which unfortunately is all the info I have about the fix for these problems.
Its possible, even likely that these issues could just be “shot out” over time by running a lot of ammo thru them for an extended break in period. But the smith works at the place that sold them to me and does not charge for stuff we buy there (at least while it is still newish), and thats a lot cheaper than 1000 rounds of 380.
Now that it works, its a very, very good gun and highly recommended. Just be sure if you get one to get it working reliably before you carry it(as you would hopefully do with any new gun that you trust your life to).
I just purchased a p-238 Nitron (black on black) and this little pistol is phenomenal for accuracy and for overall operation. I highly recommend this for anyone searching for a good carry weapon.
P238 has improved over time with shooting and cleaning. Only one FTF in 70 rounds.
NOTICE: there is a modification in the *recoil spring*. I just spoke with SS and they are sending me a new spring free of charge. They will want to know the serial number. The nice lady said the new spring should be good for 1500 rounds.
I just purchased a Nitron 2 weeks ago and ran my first 50 rounds of Remington FMJ through it last week. Had zero FTF or FTE. Everything went perfectly on all 50 rounds. Only moderate recoil and I was able to group within 6″ at 10ft and 20ft. Mine is the 3rd generation with the updated mag, spring etc. The feel and balance is prefect in my hand. While a bit on the expensive side and slightly over my intended budget, it’s working out to be my ideal carry.
