    I know on my Sig P229, the mags work for both the .357sig and the .40sw , I just need to swap out the barrel...

    As far as caliber vote, I would agree to go with .40SW.... I have both and really do like the .357sig. As mentioned, its more expensive , especially in good defensive stuff. Also, it has been my experience that the .457sig has the same problem as the .357 magnum in that it produces excess muzzle flash, which aint good in a low light shooting situation.

    I have the 40c my wife has the 9c. We love them both. I too thought about the 357. I decided to get the 357 drop barrel, probably the one from Storm Lake. Its only a hundred bucks or so and I figure with all the range time we will put in its worth the price. I'll probably even get the 9mm drop barrel just to shoot cheaper ammo. It beats buying more guns. The 40 mags will work and no other parts need to be replaced, just change the ammo out. I wanted the 357 for our hiking trips (live in Fresno, close to National Forests). The 40 cal will be my everyday carry and the 9mm can be my range ammo. Currently paying $11-$13 for 9mm, 40 cal is costing me between $15-$26. I think 357 is more than that. So it can cost me a bit. Trying to keep it real.

    I would think at that caliber it would create quite a flash...

    Sorry I noted the typo and had to "go there"... It's all good...

    Yea I have to agree. I love my .357 revolver, but the muzzle flash is bright and large.

    For me it was a choice between a .380auto (which for me is kinda not enough) and the 40S&W. My local dealer bought the one I have now, back from a guy who was moving out of state (to NY I was told) and had to leave it behind. Only 100-150 rounds through it! He made me a sweet deal on the 40c and because I had the M&P45 full size already and loved it, the decision was made easier.

    Peace...

  7. 6,

    Here's something that will save you some leg work.

    Midway is listing having a factory Smith and Wesson M&P .357 Sig barrel @ a heart stopping $77.99 as in stock at the moment. It's Midway part number 339103.

    I don't know if the same weight recoil spring is used on both the .357 Sig and the .40 S&W (they may be the same for all I know and it is possible they are) but, other that having the second barrel fitted to the gun, that's the only other minor obstacle I see in setting your gun up to be convertible between the two calibers.

    Oh, the smitty you use shouldn't charge you an arm and a leg for fitting the barrel. Most likely, it's semi fitted already and should only take a little tweaking to get it to function in your particular gun.

    Maybe a new marketing idea for the ammo manufacturers and Sig
