I am not trying to be argumentative at all. I am honestly curious if you have actually seen any measurable improvement in any of these three factors. That is a serious question. Can you actually tell a difference between stock and after market or is this all "theoretical"?Quicker follow up shots, less recoil, and increased reliability.
I already have.Maybe a Glock Amorer will chime in, and help me out here.
This.Competitors use them because reliability is often not a concern and every hundredth of a second taken off their time helps. Unless you're a competitor at that level you will not see any real world gains.
I installed this: "Jager Products Generation 4 Guide Rod -..... a captured steel guide rod for the Generation 4 Glock 17/22. These come with your choice of an ISMI 13 or 15 pound recoil spring". It came from CPWSA and cost $42.95 shipped. With a 15-pound spring it solved a functioning problem I was having with "light 9's" (WW 115 grain 9mm). It fits the pistol perfectly and it even looks good! With one of these you have the opportunity to fiddle around with different springs if you feel the need.I have a glock 17 gen 4 and am looking into upgrading the factory guide rod assembly. Who makes a good after market assembly??
