Have a rat problem in our barn. Gased up my Sig P320 just in case I came across one. Fired one test shot and NOTHING! Total jam up. Couldn't get the mag out so figured a pellet was stuck half in/out of the chamber.
This model does not dissassemble so I used a cleaning rod (with ultimately a lot of force) to drive the stuck pellet back into the mag. Got it out and opened the back of the mag and all the pellets just fell right out. I believe they were Daisy brand. A mangled pellet came out also.
I reloaded the mag with Gamo Match flat nose pellets and they fit in nice and tight. Regased the Sig and VOILA everything good again.
Now, where are those pesky rats?
