Tend to go along with Davage.
I have put in excess of 3000 reloads through the Glock 19 with nary a hiccup.
Usually use W 231 or Power Pistol but have used just about most everything else out there-Clays, Unique, Red and Blue Dot, never have had a problem. I too use a taper crimp die (Hornady) because it fits in nicely on the progressive press and kicks out nice, easily fed ammo.
Either I have been lucky with my 19 , ala chamber size being "standard" or the final crimping have done the trick.
In any case, just about all I shoot is full power reloads and it is what I carry in the magazine when I have the 19 as my CCW.
