It’s a Glock so not much to worry about. I have a gen 5 (which the 19x basically is) and just picked my 19x up this week. 2500 rounds through 19 and 400 through the 19x and as expected, runs great. It’s quickly become my favorite Glock (i have 6, yeah I’m a newbie relative to most here). Make sure you load up on ammo for your first range trip.
