I did carry a Glock for a short time, 26 9mm "mini Glock".
It is the first gun I would be willing to sell, but not because there were problem.
I can't say anything bad about the gun, fired every time.
You either love them or you don't.
I am surprised to hear about that SIG failure, I own a couple of them, P220, P232. Very nice guns.
I purchased a Kimber PRO CDP ll, what a great gun!
I love shooting it, and it never leaves my side! Well almost anyway.
I'm also trying out a S&W AirLite PD. A very easy to carry gun,
but not really much fun to shoot.
If you like the Glock, I don't think it will ever let you down.
