So the stock Spring and Mags for the 29 both work with the Lone Wolf .40 Barrel?
Yep. Sorry, meant to comment on that.
I just pulled out the factory 10mm barrel, replaced with LWD conversion barrel, loaded .40 cal rounds into the 10mm mags and started shootin. Pretty cool, really.
I believe you can do the same with .357 Sig ammo in factory 10mm mags with no issues. Just need the .357 conversion barrel.
Certainly one of the great things about the 29.
I actually bought mine to shoot .40, .45 AND 10mm.
I have a 36 that I can switch entire upper assembly (slide, barrel, spring, etc.) with the 29 upper and shoot .45acp. Need to buy G30 mags for that, though.
