Coming on the heels of their success with the single action P238 in .380 ACP, Sig Sauer released the 9mm P938 back in 2012.

Then, at SHOT Show this year, we saw that Sig had a .22 LR version of the P938 in the works, and a few months ago they revealed that there would also be rimfire conversion kits available for existing 9mm P938 pistols. I’ve been getting in some range time with the P938 recently, and we were able to pick up one of the conversion kits when Sig quietly released them a few weeks ago.

With a few trips to the range with the pistol under my belt, I was able to to put together the video review of the Sig Sauer P938 with 22 LR conversion kit that you’ll see below below.

Sig Sauer P938 9mm
The 9mm P938 comes standard with one 6-round flush fit magazine. 7-round mags with an extended baseplate are also available from Sig.

The slide for the .22 LR conversion kit is made from annodized aluminum, and perfectly matches the finish of the original frame.
The rimfire conversion kit is available with a 3.3″ barrel and night sights, or the “target” version (pictured) with a 4.1″ barrel and adjustable 3-dot sights.
Unlike the 9mm version, the .22 kit uses a barrel bushing and guide rod plug.
The .22 LR barrel has a stainless finish. Several versions of the P938-22 are also available as complete pistols, including threaded barrel variants.

The 10-round magazine for the rimfire kit is made almost completely from polymer, except for the spring.

Pro Tip: Rusty diamond plate might not be the best surface on which to rest the finish of your P938. Don’t ask how I know.

    Will Sig be offering a conversion kit with threaded (1/2×28) barrel? Would dearly love to have one of those.

    Will Sig be offering a conversion for the P238

    Not sure. I wish they did, though. They have threaded versions of their 22 kits for the DA/SA pistols, so I would bet if the existing P938 kits sell well, they will offer a threaded version. For now, if you want a threaded P938-22, you'll have to buy the complete pistol, or have the conversion kit barrel threaded by a smith.

    I haven't heard anything either way. My guess is that if they were going to do it, they would have started with the P238 instead of the P938 since there are more of them floating around out there, but I could be wrong.

    Enjoyed it very much as always the articles published at Lucky Gunner.

    I like it .but how much is it?

  7. LG Chris

    MSRP is $302 for the standard conversion kit and $352 for the target version. The standalone P938-22 has an MSRP of $656 for the Rosewood version, but I've seen it listed for sale online for as low as $550.

    Just bought the threaded barrel version. after 50+ rounds, the gun will not fire and the firing pin is not even contacting the brass. I think something just went wrong with the firing pin safety. Very disappointed considering the brand name and cost of the gun. Will be contacting sig.

    Yeah, that sucks. I'm sure Sig Sauer can take care of that for you. There always seem to be some teething issues with the first batch of any new guns, so hopefully yours is an exception. Give us an update when you hear back from Sig. I'd also love to know how it sounds if you have a chance to run it with a suppressor.
