I was recently going to clean my LCP Max. I removed the twelve round mag but could not eject the live round from the chamber (Hornady Critical Defense) as the slide would not retract far enough to eject the round and lock back. After repeated tries I was finally able to remove the live round. Thinking it might be the ammo, I reloaded the magazine with Corbon ammo and tried again but got the same result. No problem retracting or locking slide back on empty magazine, but impossible to do when loaded. Sent the gun back to Ruger and requested they inspect and repair as necessary. Ruger customer service was superb. Received an e-mail from Ruger 2 days after my gun was received saying the repairs were complete. I called Ruger customer service and asked what repairs were made and was told the barrel and slide assembly were replaced, and 30 rounds were fired to verify proper functioning. Gun was shipped back to me today. I will go to the range next week after I receive the gun, and update this post afterwards. Again, Ruger customer service was superb!
