I don't mean to upset those who feel it's necessary to clean after every use BUT. I was looking for something to do yesterday and realized I couldn't remember when I'd cleaned the 22/45 suppressor host last-one year or two??? It was tough even getting the muffler unscrewed and required some soaking with KROIL. The muffler required soaking with throttle body cleaner and punch/hammer persuasion to disassemble BUT the pistol itself only needed a couple of Hoppes soaked patches and a spritz of CLP in/on the bolt.
No round count of use but SWAG of 500 rounds since last cleaning and all with the muffler in place. Understand that nothing makes a rimfire dirty more than using the muffler with plain lead(not plated) bullets. I didn't clean more since obviously, that wasn't required. No malfunctions prior to cleaning and none post cleaning. 100 yard post cleaning group was bigger than I'd like but there was a gusting 20mph crosswind so I'm not going to complain. Twenty five yard rapid fire was OK w/o any hiccups.
