Do a 10mm or 45acp next go round. I swear, if I was made out of money, I would be putting together parts for either one right now instead of typing. Kak makes good stuff. Hahn does too, but they're way up there. Spikes also did magwell adapters. They may still be for all I know. I haven't looked in a while. And the 45's aren't really that much more expensive to build either. You just have to be patient waiting for the parts to be available.
