Back in the early 90's I built my .45 ACP using a Les Baer fitted frame and slide plus his parts. I did all the work from barrel fitting to milling the slide for Bomar sights,spent hours checkering the front strap then bead blasted the whole thing before putting in my bluing tanks. Had about a grand + into it when done and I can tell you it will be the last gun I'll ever give up.This darn gun will out shoot any thing in a handgun I've ever shot.
