I currently use a Berreta 92 in production but would not recommend it. It's a fine weapon but as stock guns go, it's not designed for competition. If for no other reason, the double action (always the first shot) is WAY too heavy. I could get a trigger job but instead...
I'm having a bespoke Limited gun built by Paul Liebenberg at Pistol Dynamics. Can't wait till I get that baby!
In the mean time, I'm going to pick up a 1911 .45 to use in Single Stack, a provisional division. I'm leaning towards a Wilson, probably a QCB. There are other 1911s out there that are more appealing to me but living in California, my choices are limited. The 1911 will at least get me used to using single action for when my Limited gun arrives.
