Customer Ron R has made a discovery for us.
Our CZ P10F Backstraps also work with the CZ .45 ACP. As you can see from the images, the brass backstrap fits flush all the way around. Thanks for the help Ron!
We rely on customers to help us with the "does this fit" problems. With all the various firearms and aftermarket parts, there are thousands of combinations of parts and firearms out there. Customer feedback gives us information that we can pass on to the next customer.
