Good choice.
I've got a G19, G21 and a G23. I wouldn't take for any of them. I worked at a LE shooting range for several years and saw tens of 1,000's of rounds put through Glocks..... and never once saw or heard of a mechanical failure. I did see some ammunition failures, like ruptured cases... usually from reloaded ammo and steel casings. The Glock has a loose tollerance in its chamber.. that allows it to feed any brand out there. The loose tolerance in the chamber is why brass fired in a Glock tends to 'puff' or stretch a little and you don't get many reloads from it.
