I was taking a pistol class and all the instructors were using Glock 21s. They gave me and the two other guys with 1911s crap about them joking around about their unreliability. Three guns had a malfunction that day. None were a 1911.
And I was running hollow points through mine cause that's all the ammo I had at the time.
But truthfully, my under the pillow gun is my Glock 23. Has thousands of rounds through it and has never had a hiccup.
