Yea - I noticed that the pin over the trigger can cause binding if you're not careful. I had to replace mine with a screw to mount an external shell carrier and after I did the action was VERY stiff (the screw was too tight, which had something to do with it). I loosed the screw a bit and put some locktite on it, now the racking action is fine. A little stiff and not as "butter" as a higher-priced, higher-quality gun, but certainly adequate. I've never had a jam, just rack it with authority. I find that yelling "get some!" at the top of your lungs as you do helps.
