I'm possibly going to be trading my gen3 G30 for a gen3 G17 this weekend, both are LNIB with factory standard sights, 2 mags, and normal Glock gear. I'm looking to make this my range gun, shoot some competitions (hopefully), and install some NS and a light of some sort for HD (for when they get past my 100 pound dane/shep mix and the chihuahua ) I have the models in my sig, so the 17 will compliment them nicely, and I've got a good stockpile of 9mm (1000+ rounds). Just looking for some input from 17 owners. I know Glocks don't need much "customization", but what are some things I should look into changing? Is the 17 a good shooter? Are you overall satisfied with it's performance? Also, does the 17 share the same frame as the 17L and 34? As I might look into an additional slide in the future. Any input is appreciated as always.
