F'k me! When I saw Elgin, I thought they were just around the corner. To the original topic, I'm not strong/consistent enough to go through a 20 round mag with a handgun and shoot accurately. To be honest, in my AR's, when I'm trying to shoot precision stuff, I like 10 round mags because they fit a lot better on a bench with bags. A full auto 22-45 with a drum mag - hell yeah!Looking at their website, it seems that Calico has moved operations from Hillsboro to the little town of Elgin, which is in the far NE corner of the state.
