I have a MKIII that is new with about 300 rounds down the pipe. I also have a YHM Mite. I WAS using CCI Quiets with the Can attached yesterday and had not one single problem with the pistol cycling (extracting the casings). Yesterday, I cleaned my MKIII, and put it back together properly and lubed her up. Today I go to fire it with the can on and it wont extract the empty shell. Took the can off and same issue. I fired some full power rounds with and without the can, no issues at all with the cases extracting. What am I missing here? Does the spring get stronger with more use lol??
