Received this Thursday, will be taking it out tomorrow morning. It doesn't fit on my older Springfield Armory frame, it rubs on the front dust cover. It fits okay on my Charles Daly 5" frame, but if you ride the slide to battery, it doesn't go all the way into battery. It fits best on my 4" frame Kimber Eclipse. No rubbing or other weird stuff.
There was rust where the recoil spring guide pin fit into the barrel underneath. How do you take the barrel out of the slide anyways? I couldn't get it angled out while holding the recoil spring away.
