Has anyone had any trouble with a drop-in barrel from Storm Lake or Bar-sto? I have been planning have a smith or Springfield do it for $300 or replacing it with a XDm, but paying half that to try it myself sounds attractive if its likely to work. I am happy with the barrel I have, But the wear on the lug looks like its going to chip soon like I have seen on other barrels. I bought the gun used so its not covered. Already looked into that.
