Sig P238 rechambered for 9mm, can it happen?
Alright, so I'm slightly interested in a 238. I'm not a big fan of the small autos but holding this one felt nice in my hands and a mini 1911 is just cool. I haven't bought one yet so this is all just speculation at this point.
The 380 is the smallest I would personally carry in an auto but would be happier with a pocket 9mm. I'm not buying a keltec so don't even go there. The 9 packs a little more punch but should still fit nicely in a pocket auto, right?

Outside of having to rechamber a barrel(assuming enough material is there) or having one made, changing some springs and making some mags, what am I missing? Anyone see a reason I shouldn't do this?

Brother, EXCELLENT idea!

Not too much material would need be removed. although bullet diameter is different.

Definately no +p ammo.

Sometimes it is cheaper to purchase a new firearm than to rechamber one. I would rather have the firearm that was designed for 9mm, than to rechamber a .380. Most .380's use the blowback design with a fixed barrel. The only (current) 9mm's I am aware of that use a fixed barrel are the HK P7 series, HiPoint, and (If I am correct) Bill Wilson had the ADP(?).
Have you looked at Kahr?

While the 238 is a locked breech design and not a blowback, I doubt there is sufficient "depth" in this gun to use the longer cartridge. The action cycle is short as is the ejection port and the mags themselves. They're a great little gun as is and very soft shooting compared to the blowback designs. Mine is with me nearly all the time...

I would just look for a small 9mm for carry if that's the round you prefer.

I think it could possibly be done, but I don't think it's worth the cost,trouble, and risk.

Look at the Kahr PM9 for a really nice pocket 9mm...

The khar is nice but I really like the idea of a mini 1911. Maybe I'll just have to find a hot 380 load or lean back towards the LCR in 357. Decisions, decisions....

Bullet diameter is the same, .356". Magazine will likely not take the much longer 9mm cartridge.

The max OAL for the 9mm is 1.169". For the .380 it is .980" That is HUGE in cartridge/gun design. I seriously doubt the mags will accept the ammo. The rim diameter is .022" larger in the 9mm so the feed lips will have to be reconfigured.

I will go out on a limb and say NO WAY!

I agree with Robo.

9mm and 380 are the same diameter. I use the same 115 grain FMJ to reload them both when I use store bought bullets.

When you call it a pocket auto, are you thinking of carrying it in a pocket? I carry an airweight J frame in a pocket holster. I would just be concerned about carrying a 1911 style pistol because of all the edges that could get caught in your pocket.

Does anyone here carry that type of weapon in a pocket holster? If so is it difficult to draw quickely?

I used to carry a Taurus M-85 that way. But the hammer did get caught a few times. My J-frame has the concealed hammer.

Rick, I thought about it snagging on stuff but I think NGIB carries his in his pocket. Hopefully he will be by shortly to clear that up for us.
