First of all this is my first post on Glock Talk, but I'm hoping to get a lot of replies on this one because I feel like the more input I get, the better informed my decision will be. I'm a huge fan of polymer framed, full size 9mm handguns. I've had a G17 Gen4 for about a year and love it, threw some triji nite sites and a tlr1s on it, but now I feel like its time to expand the collection. I'm looking for a high quality, full size polymer 9mm, preferably right around $500. Right now I'm split between the xd9 carry, m&p9, and sig sp2022. Have done research on all 3, but would like the input of you all in the Glock community since I currently own/ carry Glock. All input is a big help. Wanna kill these ads? We can help!
