Upgrade your firearm with the NDZ Performance G20 Extra Power Recoil Guide Rod Kit for Glock GEN 4 - Black Adapter.

Fits GEN 4 Glock Model(s): 20, 21, 40 & 41.

Does Not Fit: GEN 1-3 or 5.

The NDZ EPR Kits provide a decisive advantage for all Glock owners. Special features include a rigid stainless-steel body that improves lock up by completely removing "guide rod flex". The hex screw removable tip allows the user to choose various spring weights that will calibrate the ammunition to their Glock.

Included in this Kit:
  • ( 1 ) - Black Anodized Steel Gen 4-5 Guide Rod Adapter.
  • ( 1 ) - Stainless Steel Guide Rod with hardware.
  • ( 1 ) - 3/32" Allen Wrench.
  • ( 1 ) - 20lb ISMI Reduced Recoil Spring.
  • ( 1 ) - 22lb ISMI Reduced Recoil Spring.
  • ( 1 ) - 24lb ISMI Reduced Recoil Spring.

The NDZ Generation 4 Adapter Ring installs under the retention end screw thereby making up the difference of space in the front of a generation 4 slide as well as retaining the spring accordingly.

ISMI premium springs are manufactured exclusively with certified aerospace specification alloys; stainless or chrome silicon. Then the springs are heat treated, shot-peened and stress relieved after winding to enhance performance and durability.

Please make sure you are using the correct loads for the springs or you will have cycling issues.

5 of 5 EXCELLENT! March 1, 2021
Reviewer: Frank from North Fla  
This is an excellent recoil spring kit for the Gen 4 / G21.
I typically shoot hotter handloads and / or +P Federal HST ammo. The 22# spring settled my G21 down for faster follow up shots with the HST ammo.
I use the 20# spring for my hot loaded handloads and I was amazed at how much smoother is shot.
This is the recoil spring kit you're looking for.

Best part was NDZ had it on the road to me withing 48hrs. I'm very pleased with these folks and will use them for other parts.

5 of 5 Gumby No More! July 9, 2020
Reviewer: TexasBEAST from Houston, TX United States  
Took the flex right out of the stock G4 plastic guide rod, and gave me the option to upgrade to different springs as I pour on the 10mm heat. Easy install with the NDZ Guide Rod Tool. Pretty much fuhgettaboutit it, without.

I do wish these kits were offered with the option of guide rod finishes. I prefer my stainless guide rod adapter to match my guide rod.
