Not much of a GlockGuy myself but do have a Gen 3 19 and a Gen 4/40.
The Gen 4/40 is of course the long slide in 10mm...great gun for what I wanted it for...
Have shot Gen 4 and Gen 3 19s and much prefer the Gen 3. Prefer the less aggressive checking on the grip and smaller magazine release. Would however prefer the larger slide release but the stock one works fine. The trigger pull as measured on a Lyman gauge is a 3.5# take up and 5 pound 2oz break...that is fine for me.
