I built these Glocks and they do not work. I’m sure a Glock person can get them going but I do not have the time or patience to mess with them. The Glock 17 gen 3 does not cycle correctly and the triggers on the 357 sig Glocks do no reset. Yes they can be made right but like I said I do not have time to deal with these. Two are brand new and have never been fired and the Glock 17 has issues. Holo sight is not included. My loss is your gain. Come get them. Ridiculous offers will be ignored.
