I own and XD-40 and am becoming more and more interested in trying the .357Sig caliber. Doesn't seem I am going to need to do much in the way of modifications. Is a new barrel conversion all that's required?
You're right, you only need to change the barrel. The only manufacturers I know of that make aftermarket barrels for XD are EFK Fire Dragon and Bar-Sto. Some people also upgrade the recoil spring to heavier weight but this is a matter of personal preference.
