Right slide is an early(1st edition) FI Model D CPA S#. Notice The Ejection Port . That needs to look like the slide on the left
These pictures and trial were provided by Mr. Nolan. I have always thought this would fix many issues but didn’t have two different slides. Mr. Nolan found both slides and provided this information to me.
Thank You Mr. Nolan
This shows the early CPA# ejection port ground similar to the later editions. This can be done with a Dremel and lightly take the ejection port down. This will fix 90% of the failure to eject problems out there. As always if you have problems you can call me at the shop 513-248-1843 if you leave a message I will get back to you.
