The Harry's works as a gym shorts AIWB rig, but it prints like crazy for me. My 642 with boot grips actually prints much worse than a G19 in a JMCK Wingclaw 2.0. It's worse than a G19 in a DSG Orion. For some reason the Harry's causes the butt of the 642 to stick out about 15 degrees from my torso.
The Harry's is a very well made holster, and service was good. But I can't wear it if discretion is required. I'm going to try the DSG Apolo in a 3" version. YMMV.
ETA: I don't have a problem with the factory 642 trigger. A lot of dry fire seems to have helped. I'm cautious about trigger jobs on wheel guns. I sent a K frame to the factory for a PC trigger job and received a nice trigger that wouldn't ignite primers reliably. Sample size of 1, etc. etc.
btw: Desantis pocket holster is too big for a lot of my pockets (32 inch waist). I much prefer a pocket holster I purchased from Walmart. I think it's a Uncle Mikes.
