Just curious about the Lone Wolf connector and a Gen 4 weapon. I put the LW 3.5 connector into my Gen 4 27 and found the slide fairly difficult to rack. I put back in the OEM Dot connector and everything was smooth and easy again. I've thought about ordering the Glock Minus connector to put into my 27, thinking that might alleviate that condition.
I put the LW connector into my Gen 3 26 and it worked out just fine.
