Can anyone tell me if an xd45(fullsized tac model or any model really) can be converted to 40 super? Because this is my first post I want to say I have experience with guns and gunsmithing, as I worked in a shop as an apprentice before. I understamd aboit more powerful recoil springs and timing and all that, but really I am just looking for info if anyone has done this or knows a good company to get a barrel from in 40 super for an xd. I am only interested in 40 super, if I cant do a 40 super I will just stick with 45acp stock barrel. Thanks.
