I have one of these. Mine is fussy on being cleaned. Good for between 75-100 rounds before starting to FTE, FTC. Depends on brand of ammunition. Some goes longer. Clean the chamber and barrel with bore cleaner, bronze brush and swab, then one drop of oil only on swab. Try chambering and extracting a dummy cartridge (or if NA use a live round CAREFULLY with safety on where it is safe & legal to discharge a firearm, not in your house). If you can see issues, you can correct. The extractor sits in these without a retainer and can get out of place and the spring can be lost. You have to remove the forend to loosen the screw on bottom to lift off the barrel. The slide will then slip off forward. There are two holes in back of the slide. One of them is off centre for the guide pin with return spring to seat, the other is larger. Ensure the return spring guide pin is in the correct hole. The slide should come all the way back to end of travel without binding. There is a pin that sticks up out of the action to act as ejector. These can get bent and cause problems. Make sure it isn't binding on the slide.
