357sig barrel for P250c 40sw

Jig Sawer · 04-29-2012, 03:17 PM

I'm thinking of a 357sig barrel for my 40sw. Now, is this all I need or do I have to get an X-change kit? I'm wondering about the outside dimension of the 357sig barrel being the same as the 40sw barrel?

I'm sure I'll need a kit for 9mm and that's for the slide assembly and the mag, right?

For those who shot 357 with their 40sw guns, how did it go? More power? More accurate?

Thanks.

I cant speak for the P250, but I do know that the conversion from .40 to .357 in all other Pseries just requires a new barrel. The .357 case is just a necked down .40 case, so outside dimensions are the same.

Mags also work for either.

So that's a pretty good indication that it will be the same with mine. I noticed that my mag is marked 357-40.

Thanks.
