When did Glock move to the double spring on the guide rod? I just picked up a G26, that I am fairly positive is a Gen 3 (doesn't say Gen4 on rhe slide), but is has the double spring rod. Haven't had the chance to take it to the range yet, but I'm sure that it will be as rock solid as my G31. Thanks for the help. Wanna kill these ads? We can help!
