Just picked up a Gen4 19. Austria inscribed. 3/04/13 test date. New to Glock, and this feels pefect in my hand. I'll be going to put a few rounds through this weekend.
There was no damage anywhere like has been reported in threads here.
I also own a P229 Dark Elite in 9mm, and a S&W 66-2 that has had an easy life and is in pefect condition. Nothing but the 158 gr. 357, but mostly had 38 run through.
I'm in Illinois and if we get CC, and the 19 runs well, I'm thinking of maybe going to a 26 for carry duty. Anyone carry the 26 daily here.
