## Customer Reviews

### ⭐⭐⭐ 







  
  
    Good quality,  but flawed design
  

*by K***P on Reviewed in the United States 🇺🇸 on February 9, 2022*

This looks great and is built with quality but fundamentally a round jam but,  knurled or not, is harder to grasp with a tool.  If you're going to be hand tightening it you'll be fine,  but otherwise a nut with flat sizes works better.

### ⭐⭐⭐⭐ 







  
  
    a little thick
  

*by B***D on Reviewed in the United States 🇺🇸 on November 21, 2021*

works ok just a little thick

### ⭐⭐⭐⭐⭐ 







  
  
    Just what the P938 needed.
  

*by C***S on Reviewed in the United States 🇺🇸 on December 22, 2021*

Perfect fit. Just what I needed for a head spacer on my Sig P938.
