After reading this thread and shooting an IDPA match that required hammer down where I normally carry cocked and locked...I realized I'm not as much of a DA/SA fan as I thought I was. It makes sense though as all the range time and training I've done was SA only because I always start cocked and locked. So, I replaced the variant 1 parts of my USP-T with LEM parts. The result? As far as a range report, I first noticed my grip was well, wrong. The first magazine hammered the thumb knuckle at the edge of the web of the hand and I figured "Ouch, I'm doing something way wrong." The second magazine I made sure the web of my hand was nestled all the way up and I still got hammered on the first 2 rounds. Hrm, time to re-evaluate my grip. Apparently I was riding the lever that no longer existed. I let the pistol rotate slightly to take up the slack so that my thumb can rest parallel to the frame again and the hammering goes away -- then I notice my groups tightened up. I let that soak in as I got to 40/100 rounds for the day. The next 36 rounds were slow fire and getting used to the much shorter trigger reset. The next 12 rounds were double tap left double tap right. The final 12 rounds were single shots on a pair of targets with followup shots on a pair of targets. I am not ready to attempt a triple nickel or anything, but I am pleased with I did for a first trip out on a new trigger. I think I'm a fan, but I've got several thousand rounds though the pistol in a variant 1 configuration and the muscle memory is reassuring me that the trigger reset is another 3/8ths of an inch forward of where it actually is now, so I have some retraining to do for faster followup shots.
