Question: is this product made in the USA?
Document: Doesn't fit my gen4 19 completely different size, not a product defect but the rod wasn't in the package when it arrived was just rolling around in the envelope.
this spring is great quality and replaces a plastic factory spring. First time shooting could see a substantial reduction in muzzle flip, love this product.
Solid product...no detrimental changes in performance or accuracy...gun may have felt a little more solid with this spring (g19). It Seems a little more professional. In addition, the set screw was good and tight. I was going to put a drop of Loctite on it but couldn't get it loose...so, that is a good thing for now.
I purchased this steel guide rod after my Glock 23 .40 caliber, plastic guide rod broke (after about 10K+ rounds). I never really liked the idea of a plastic guide rod anyway. With this steel guide rod it adds a little bit of weight but this actually helps in recoil management. So far I've put a couple thousand rounds with this guide rod and everything is working great.I would recommend this product to friends, family, etc.
this steel guide rod is a lot better than the plastic one they install in the glock, i would recommend this one and the price is fine.
looks good. haven't shot it yet, but by the quality it should be a lot better then stock. hope this helps
This is a great replacement recoil spring for my Glock because of the stainless steel guide rod. I will keep my original Glock recoil spring with a polymer guide rod as a backup.
This is a controversial add-on to your Glock.It definitely adds a little more weight to the front end of the firearm, feels a little more balanced than with the stock guide rod. I know all the hub-bub about the steel or tungsten upgraded guide rod (they do nothing but make your wallet lighter), I bought mine simply for the added weight. If you're looking for a miracle fix to get rid of your recoil buy a .22 handgun.
This doesn't pass the Glock recoil spring assembly field inspection test. A test to ensure that the spring is strong enough to chamber a round even if the pistol is dirty, dry or firing underpowered ammo.
My Glock 19 seems to function just fine with this after market part. Didn't improve my accuracy like I had hoped.
Answer: no
