Gents,

I have a .40 S&W Practical model. Has anyone coverted any of these to .357 Sig? I would think that only the barrel would have to be replaced. I would think that the .40 magazine would work with the Sig round. Am I off base here?

Any chance of Browning bring out a factory chambered .357 Sig?

22 Conversions: Who makes the best?

Kind Regards,

Ceiner and Dealer Warehouse have .22 conversion kits. The Dealer Warehouse ones are Argentine made.

Novak, C&S and I believe almost all of the name HP 'smiths do .40 - .357 conversions. It's not a big deal. Basically, all that is needed is to "drop in" a .357 barrel.

yes but my concern would be. is the frame strong enough to take the .357 pounding. day in and day out ?

It's an interesting question. More pressure but less power (the 40 will launch a bullet 10 grs heavier nearly 50 fps faster).

I am just not sure but I don't figure the .357 barrel will wreck a .40.

I have not fired enough rounds out of my regular 9mm P-35 Converted to .356 TSW enough to tell whether it will camage the gun or not. I is however a bit more intense than the .357 Sig round ( most of my ammo is Cor-Bon which drives a 124 at 1500 fps).

Good luck with the project Wes!!!

The frame can take it using the heavier .40 slide and recoil spring.
