I stopped by my local gunshop on the way to work today. He had a used XD in .357 Sig that he just took in on trade. I had an XD(m) a while back and did not like it. I thought I would give this one a try, I have never had a .357 Sig before. The inside looks like it has been fired very little and the outside is probably 90%, I gave $325 for it. I am interested in getting a replacement barrel in .40 S&W that I can drop in. Does anyone know where to get one at a fair price? I looked at a few of them and I just don't want to have to pay $200 for one.
