I've got an older (late 1990s) Sig P226 in .357 Sig. If and when ammo prices and availability ever stabilize, I'm considering turning it into a full-time 9mm.
I've already got a Bar-Sto conversion barrel and never had any problems, but heard you shouldn't rely on the conversion barrels for anything but the range. Would the 9mm X-Change kit work on an existing .357 Sig frame? Does there need to be an additional conversion with the locking inserts? Thanks!
