Excellent design, no competition out there. I ordered the slim bushings but they were not slim enough for my VZ thin grips. I had to order the extra slim instead.

I ordered the extra slim and the slim bushings and both worked perfectly and solved my issues with thin grips fitting properly. The 7/32 drive is an amazing idea and the fit tight and lined up great. I also picked up some SOS screws in black and stainless and then just set the grips off. I think I will continue to order bushings and screws for all my guns.

I’m very impressed with the high quality and innovative design of these hex drive bushing. I used the extra slim bushings to install a set of very slim grips (less than .174 inch) on a Sig Sauer Traditional 1911 Ultra and they fit and worked perfectly.

The extra slim bushings work perfect on my slim VZ grips. At .190 thickness, go extra slim....I'm glad I did. Perfect fit and quality second to none.

I needed the extra slims to fit some Esmerelda thin grips. These bushings were perfect and sta exactly right. Very easy to install. The only trick was getting the rubber o-ring to sit just right. I would definitely order these again.
