For some folks Glock ergonomics dont cut it. Ive never had a SIG that wasnt 100% reliable, including several in .38 Super.
I got turned on to Glocks by a cop friend years ago and do carry a G-19, but I will admit that I don't keep a round in the chamber.
Son and I were out at the range today and my Glock just shoots so nicely, son does outscore me though with his Taurus PT-111, which he EDC's.
