Followup:
BryanP nailed it: I want another gun, and I also want something with less recoil for teaching new shooters. I want something between a .22LR and a .45ACP, and the 9mm fits the bill perfectly. Plus, having another gun is always good, and yes, I know the "cheaper to shoot" bit is a flimsy rationalization.
Bratch was kind enough to let me shoot a few things today. My thoughts (I'm looking for rebuttals here; feel free to convince me I'm wrong):
CZ-75: a lot of take-up and a fairly heavy, mushy pull in the trigger. Watching carefully, I saw that some of the travel was actually overcocking the hammer. Good ergonomics, but I didn't care for the trigger. Accuracy was indeterminate; the trigger drove me nuts, and I was flinching on most shots (which I dont do with .45, or .357 Mag).
Kahr (don't recall model). Neat for concealment; too small for my hands for general range use, though. DAO; not what I'm looking for this time, but if I was looking for something highly concealable for defense use, I'd give it some serious thought.
BHP: The trigger was crisp, but fairly heavy. With practice, I kept the nose-diving to a minimum. Ergonomics were great. Sights were pretty good--the front sight was a little narrow for my taste, but that's what aftermarket parts are for. With a trigger job to lighten it a bit, I think this would be great. As with most guns, the trigger seems to be hinged at the top, rather than being a straight-pull like a 1911; other than a 1911 chambered for 9mm, does anybody have a recommendation for a 1911-like trigger?
Thanks, all for the suggestions. It's nice to have a place like this to come for information.
