The .40 and the .357 Sig should be the same mag. In fact, most Sig factory mags for both pistols are marked '40/357', not sure why those aren't. But since the .357 Sig is based off the .40 parent case, the same mag works for both. Or at least I "THINK" they should, LOL!

the mag for a 239 using a 357 sig round is necked down so it will not work with a 40. The mag for the 40 is not necked down at the top and will work with 357 sig. I have never had any problems with this. I however believe the actual 357 sig mag will better present the next round if using for a self defense situation where you wish there to be no doubt of reliability

For the double stacked mags .40 and .357 are the same but like roym pointed out; not so with a single stack for the p239. 357 will work in the 40's but not the other way around.

Gents,

Picked up a P239 for my sister about six months ago. She loves it!
