Thank you all for the information. I was not aware that there were semi and auto parts. If anyone is looking to sell prior to listing on GB please shoot me a pm.
Green mountain used to have the 45 barrels check with them. The hard part is the 45 bolt.
One would think so, but I had a lot of issues trying to load very many rounds in .41AE or .45 magazines. I could really only get a dozen or so rounds in the mag to run. Otherwise the stack pushes outward too much and binds.That's a good call on the 41AE mags, I suppose I could use those instead of swapping the GG lower if I'm also out shooting 9 or 22lr with the stock grip and want to switch up to 40.
