Put a few hundred rounds through several 17M and 19Ms today. While there are a few minor improvements a Glock is a Glock. Improved trigger, no finger grooves, ambi-slide stop, etc. All which make the gun a bit nicer but nothing that turns a major corner. I liked the beveled mag well and a higher profile slide stop. The lack of FGs is a long overdue improvement. If you like the Glock, you'll like this one better.
