Hi there I wouldn't describle it as uncomfortable and it doesnt really take much effort to be honest and im a bit of a lightweight . However it has an automatic safety catch and when I first got the rifle I found that I wasnt cocking it "properly". i.e. I wasn't taking the underlever all the way back until the safety catch was engaging. So I'd got to take my shot and found i hadnt actually cocked it. I wouldnt really call this a problem, it was more me being a div. Its the kind of thing you do once or twice when you first get the rifle and then you dont do it again.
