Most Helpful Positive Review good quality
Haven’t been able to shoot with it yet but fits with ease and is flush with the slide where end protrudes. Will review again once a sufficient amount of shots have been used. So far an awesome quality product!

Spendy but excellent

by YankeeBluejeans, Verified Owner from MN, United States Written on October 3, 2025
Bought the stock weight 18lb for my G47. It looks and feels very well made. Installed with zero issues. Cycled like a champ with target and carry ammo.

Springs wear out eventually, so keeping the factory recoil assembly is a no brainer.

Some of the reviews seem to think that futzing with engineering specs should still be reliable. It's always a compromise. Be sure to test test test your upgrades before you place into service.

Compensator and Ammo Jams

by Steve N, Verified Owner from OH, United States Written on August 17, 2025
I purchased this as I hoped the lower weight from stock would fix my ammo jam issues (double feed, stove pipe, failure to extract, etc.) when using 115 grain ammo with my two compensators. It didn't make a difference. I've returned it.
Pros:
  • Easy to install
Cons:
  • didn't meet expectations
Best Used for:
  • 124 grain and higher
Would recommend: No

Great little spring

by Andy, Verified Owner from MS, United States Written on August 12, 2023
I installed this on a Glock 19x in combination with a Zev compensator and silencerco threaded barrel. I ran a few hundred rounds through it with no issues until I started using some cheap reloads from the range. As long as I was running Winchester active duty 9mm however, it was flawless. I'm no gunsmith but it seems fine to me. Fits perfectly and looks nice. Feels and looks well made.
