Gump & Pat:
I understand your shock and dismay! Do not fear; I have not forsaken the 1911. I am just dallying in Production for a bit of a change of pace.
I've been documenting here: Adventures in USPSA Production Division
I'm still shooting 1911 Single Stack at Terre Haute/RileCC/WVPPS, and using a 1911 for 3-gun and multi-gun, but I've been hitting some of the other pistol matches in Production Divison.
It's . . . not the same! My biggest problem so far is with trigger control. I've apparently been spoiled by my 1911 triggers, and the crunch'n'tick on my Browning BDM is far less forgiving. The worst part is that the trigger reset is more than a quarter of an inch and there is very little force pushing the trigger forward to reset it. So I get trigger freeze frequently. I also forget and leave the thumb safety "on" occasionally, but that's just being a doofus.
I have some extended factor mag releases for my Smith & Wesson 5904 on the way, and if those work for me, I think I can do a little better. I still won't run any faster, but I'll be able to contentrate on the actual shooting and transitions if I'm not fighting the gun trying to get holes in the paper.
A side benefit is that this has apparently improved my trigger control when I shoot my 1911. It's kind of like shooting revolver for a while, but less annoying.
