B.I.L. and I finally got the time to machine replacement bushings/spacers for the CZ 40P. They turned out great. We tested one today, and they work great. They are made from Black Delrin. This material proved to be harder and more durable than the factory white plastic.
Close-up.

The one on the left is after 100 rounds of Winchester Value Pack ammo. The one on the right is a new one.

Factory chewed up white bushing shown with a few that we made up.

Just threw this one in for fun.

These can be purchased on our website.

Also please note. If you are using Wolff Springs in the gun. The inside diameter of the bushing/spacer needs to be made a little larger. Please let us know if you need this done.
