I own one Sig, the M18. Only other Sig that we ever had was one of the original P320's that my wife bought but never could make run for herself. I could shoot it just fine, but it was her's so after it didn't work for her we went to Wilshire range, rented several models and ended up trading it for a G19 for her. She owns a G19 and G17. I own zero Glocks.
I bought the M18 because I wanted something with bigger round count to carry, and it was my first polymer gun besides a couple pocket 380's and a S&W Shield. Plus I wanted something in FDE for a change up. I don't like Glocks grip angle, and honestly would've went with a M&P but they didn't have one in FDE with night sights, so bought the M18. I haven't shot it a ton, but no issues yet.
