my boy used to own a cobra .380. it jammed like crazy then one that fired and jammed got stuck in the chamber. so happens that the barrel cracked and it got stuck futher in. this happend the 2nd time we went to the range. they said send it back and they sent him a new one. look on youtube. i bought a bryco j22 thats very unreliable and there were ways on youtube to make it more reliable. mainly polishing feed ramp, polishing trigger for lighter pull, etc. also depends on the ammo!! do some research on that particular gun. there should be write ups or vids to make it a better gun.
