Beretta Px4 storm .40 s&w.(The glocks don't fit my hand comfortably) It is insanely simple and quick to take apart and very low recoil by its very special design. I love mine. I'd also consider a model 1911, but a good one won't be $400 new. And sub compact's are boring mainly because I like to shoot my guns at 25-30 yards and the accuracy would suffer on a smaller/same caliber pistol compared to a larger one.

Maybe a Taurus of some type would be my next choice.
