Does anyone here know much about this gun. I recently purchased one. Ii love the caliber, I've had lots of 40's. I just don't know much about this one. I know that it's built like a tank.

I know my wife has one in her safe. I know it used to be mine, and that I didn't really want to give it up at the time. I know they're discontinued and that spare parts and magazines are getting harder to find. I know it's a very well made little pistol that simply got pushed out of the market by lighter weight and higher capacity polymer guns.

Anything in particular you want to know?
 
I've not done much research on it just kind of a sudden purchase. I liked the hammer with the small hammer spur. Seems like that's difficult to find unless you get a 1911 or clone. But yes is this aluminum or steel framed that was my main question it's heavy but I like that about it. Thanks
 
good guns, I just picked a 9mm P239 up a few weeks ago. Very soft shooter. I can't say how accurate mine is because it has some funky aftermarket i-dot sight that I absolutely hate and can't shoot with for beans, but it was very reliable when I shot it, despite my not being able to hit anything. Not a single malfunction in the 200 or so rounds I put through it, and those were cast lead reloads of varying strength from mild to full power.
Buy extra mags now. They are still available for $30 or so, but they won't be for long.

As other people here have said, other options, some of them by Sig itself, rendered the P239 obsolete as a CCW. If you must have a hammer, a Sig P938 is much smaller, and only gives up one round to the P239. A Sig P365 is tiny compared to the P239, carries 2 more rounds in a flush fit magazine, and is significantly lighter. The P239 really had no market niche in which it remained competitive.

Once sig released the P365, the writing was on the wall for the P239.
2 more rounds and 7 less ounces for the P365 on the left.

Great handgun but 40 s&w? Don’t you know it’s obsolete? You’ll never find ammo for it.


:rofl:
I've been hoarding speer gold dot 40 ammo for a long time now. I've got 2 other 40 's.

I got 4 magazines with it too.
 
Sometime around 2010 a friend invited me to his range and he brought along his P239. I had never shot a Sig up to that point in time. He brought along a bunch of bulk .40 WWB jacketed flat point range ammo. All I can tell you is I instantly fell in love with that pistol. It was incredibly accurate. With cheap (at the time) range ammo, it took no effort to tear out the black of a 25 yd paper target, and I could regularly ring a 12" steel plate set out to 100 yds.

Next opportunity I was at my LGS looking for one. While he didn't have a P239 in stock, he did have a P220, and being a long time .45ACP fan, I got that instead and was not disappointed with accuracy or reliability. If I ran across a P239 today it would take some serious will power not to grab it.
 
I had one in 357SIG. They are good guns and shooters.

My only complaint with them was the grip panels are a tad narrow and need some swell through the palm. With the factory panels on the gun, it liked to squirm around in my hand when I shot it. I put a set of Houges on it and that solved the problem.

One thing you will want to watch if youre buying mags is, the early mags were caliber specific, and the 357SIG mags wont allow you to load 40's (the 40 mags work with the 357SIG). Those 357SIG mags had an offset in the mag body at the bottleneck of the round. Later on, they stopped doing the offset, and the mags for the 40 and 357SIG would take both without issue and are marked with both.

Thanks so much
 
I currently own the P239 in 9mm and .40. Extremely accurate and the .40/.357 versions are a bit beefier in the slide. I had a .357 too, but that specific example was a bit floppy in the slide to frame fit and I sent it down river looking to replace in the future. My .40 seems to print the 165 gr full power loadings right at the top the front post, and are my preferred load. I agree on the factory grips being a bit skimpy and have the Houges on mine.
 
One of the first guns I bought years ago,(used) I was on a Sig craze. Still have it, have not shot it for some time. Great guns, all of them. Heavy duty, well built, better than all these new polymer guns. Back when Sig was Sig!:)

Now you scratched an itch, now I need to load up some 40 SW and go shoot them!

I'm a big .40S&W fan, too. I reload, so I don't have to hoard, plenty of brass and bullets available. I don't know much about the Sig, but I have two .40's, used to have a third but a friend was interested in it so I sold it to him, it's a discontinued model (SR40C Ruger). What are your other .40's? My EDC is a SA 1911 EMP4 in .40, and I also have a BHP in .40.

Yep, my 9mm P239 SAS Gen2 was a trade-in for a P365 before I got it it brand new condition, this and my Sig P6 are 2 of my faves.
 
The P239 was discontinued in 2018. It couldn't really compete with Glock's G19 or G23. The main drawback was it's low capacity and high price.
SIG then went one step further and stopped making guns in 40 S&W and 357 Sig all together. (Glock still offers 15 variations in 40 cal guns).
The P239's are ok, but I'd secure spare parts if I intended on keeping it .

I wanted to illustrate this difference since I happened to have a picture of the two mags from some time ago. I've always preferred the .40 magazines since they do work with both.

I have a Smith and Wesson sigma in 40. And I have a Glock in 40. I'm really into the 40 thing. I've got a Rock Island Armory that is tricked out. It's in 10mm. I also have a kel Tec p40 in 40 Smith. That gun is very small about the same size as a little 380. Believe me when I say it's will deliver a jolt in recoil.

The P40 will get your attention :D

I picked up a .40 P239 police return a few years ago. CDNN had BNIB Sig threaded 9mm P239 barrels for about eighty bucks,
and Sig forums suggested it was a drop-in on a .40 chassis. It was, functions fine, even with .40 recoil spring and .40 mags.

The .40 chassis can also take a .357 Sig barrel, and vice versa, from forum chatter. The 9mm P239 was apparently a tad
slimmer, and can't do the caliber swaps.
 
I had one, also in .40. It was an absolutely great shooter and I shot it better than my issued Glock 22. It also was very well built and cycled any lighter reload I fed it, including ones my Glock wouldn’t.

I ended up selling it due to the size/lack of capacity and it being a different action than my work piece. But it was a damn fine pistol.
 
SIG came out with the 239 about 30 years ago, as best I can remember. Back then they primarily made duty size guns that were not very concealable. The first offering in the 239 was in 9MM. I bought one, new, at a big box store in Florida for around $550 out the door...big bucks back in the day. SIG’s marketing effort was advertising them as “personal size” pistols.

Don’t remember when they came out with the 40, but I acquired one of those, part of SIG’s, Certified Pre-owned program, on GB back about 2008. Almost identical in size except that the slide is a bit taller and heavier. My 40 looked like new...still does. One of the things I like about the 40 is that you can easily convert it to 357 SIG just by changing the barrel. If I were going to take a handgun to a gunfight it would be a 357 SIG...although my first inclination would be to take a long gun to a gunfight...would bring some friends with long guns too! The 357 SIG round is extremely effective for its intended purpose. That said if all I had was a 40 I don’t think I would run around feeling sorry for myself.

Completely agree with you on the .357 Sig! If agencies weren’t limited by weak cops and expense of ammo, that caliber would be the top choice in duty guns.
