I recently picked up a consecutive S/N# set of G-17 RTF2s. One is to be a range beater, the other is a spare I guess.
It performed flawlessly as anyone should expect. I fired it on the move, around cover, under the truck, standing, sitting, kneeling, one handed, weak handed, you name it.
It was a windy South Texas day and it got a little dusty, but nothing I would consider excessive.
I lubed it before the session with Breakfree...
