Shot the 19X yesterday and I'll say, it shoots about like any other Glock I've fired. After the first bang I had a FTE. cleared it and continued on. The gun had four FTEs during the first 60 or so rounds. Tried all three mags and that didn't help. I put it back in the box and figured I'd take it back to the dealer I bought it from. Pressed on with the Sig and Kimber. I decided to try the 19 again and had a box of 100 that I ran through it and the gun ran flawlessly. Maybe I had some ammo that it didn't like, but I thought Glocks were immune to ammo differences.
Anyway, I like the longer grip and the night sights. The trigger pull is a tad shorter than that on my 23.
It is your basic Glock that looks cool.
Although my Sig P229 Legion cost nearly twice as much, I'll take it any day over the Glock.
