MikedaddyH Posted June 1, 2012 Report Share Posted June 1, 2012 Can I convert my XD-40 to a .357sig with just a barrel and spring change ? Or do I need to get new Mags ? Quote Link to comment Share on other sites More sharing options...

Robocop1051 Posted June 2, 2012 Report Share Posted June 2, 2012 I have seen the Sig P226 swapped from .40 to .357 with just a a barrel swap, and the same mags used. I think Glock is the same too. I don't see any reason why XD's would be different. I'm sure that the different model numbers is because of labeling/engraving of the caliber on the mag.

MikedaddyH Posted June 2, 2012 Author Report Share Posted June 2, 2012 Robo , thanks that is what I was thinking. Two sites stated that the Glock and Sig swaps didn't need a mag change but there was no info on the Springfield XD. The .357sig rounds fit in the 40S&W mag with out any issues.

Robocop1051 Posted June 3, 2012 Report Share Posted June 3, 2012 I'm not an expert on the round, but I believe the .40S&W and the .357Sig both came from the 10mm Auto. I would expect almost all their measurements to be the same, minus case length.An impressive bullet. The .357 Sig fills the gap between the .38 +P+ and the .357 Magnum... And it does it in an automatic casing! It's too bad that it's popularity didn't take better. It might be that it doesn't really surpass the performance of the 9mm by much, and you lose the ammo capacity of the 9mm. Quote Link to comment Share on other sites More sharing options...
planeflyer21 Posted June 3, 2012 Report Share Posted June 3, 2012 That, Robo, and ballistically it is very similar to Super .38, which retains a high magazine capacity due to the straight walled cartridge.I also believe the bottle neck turns off reloaders used to straight pistol cases.Jon Quote Link to comment Share on other sites More sharing options...
