When my wife bought her Sig 226 I gave it a try. It felt nicer in my hand than my Glock 17 (at that time) but, I didn’t shoot as well with it as I did with my Glock. Maybe it was just the novelty of the Sig, being used to my Glock. I have no complaints with Glocks and I shoot well with my G19 with RMR.
I had a FN FNS and my fat hands kept accidentally putting pressure the ambi mag release. So it had to go.
Now I know why lefties bitch so much. A reversible mag release makes so much more sense.
