How bout a compromise
Long answer:
Get a P99, then drop a Glock striker spring in! It reduces the felt trigger pull. But don't put a 4 lb spring (Wolf) like I did, use a 5.5 lb.
They do grip reductions/changes on Glocks, but they are pretty ugly.
USP is hard to argue with, but do cost a bit more.
I've only tried the LDA in the stores. Hard to imagine fast doubles, but tell it to Jarret! I'll borrow a fellow shooter's, as I'm beginning the hunt on a .40
Guys I know with Berretta's get the trigger worked on. With pretty good results too.
Short answer: Get over the striker thing, get the p99
