My one encounter with their CS dept was disappointing as well, but nowhere near as bad as yours. It's too bad. My experience soured me on their products as I'm sure yours will for you.
I've got a PRI on my 3 Gun rifle and had to file a flat on the side of it so a locking nut could be installed to keep it from changing its setting during a match. I'd recommend looking into the Syrac. I've been thinking of switching over to that one myself.
I recently moved from Missouri to Florida and drove all of my guns/ammo down. I completely avoided Illinois and all was well. The felon you'll be riding with has me worried for you though. Good luck
I've been running a Tac Sol TSG-22 on my G34 for a while and it's a pretty good kit. They've got a kit for 19/23's as well.
