Sorry but I searched everywhere and could only find information about gen 3 to gen 4 compatability...not gen 4 to gen 4. I have a Gen 4 26 and a Gen 4 27. I am a little (ok, a lot OCD) and I partially scratched up my receiver on my G26 when replacing the extended slide lock lever. Ive replaced those things a million times, but for some reason this one was a PITA to get out. Anyways, I was wondering if I could simply slide my Gen 4 G26 slide onto my Gen 4 G27 receiver without any modifications or would I have to change out the trigger mechanism/ejector parts on my G27 receiver? Thanks in advance!
