well, if it worked when you need it, it would be fine, but, if it did not work, the attacker would probably be infuriated. i know i would be. how good are you using it as a short club? personally, i would find a way to fix it. whether that means trading ammo at the range, or keeping the gun totally spotless, cleaning it every night. try diagnosing the problem when it occours. feild strip it right at the shooting bench, and check the various parts to see if something is sticking, getting gummed up, if you can find a burr somewhere. a gun will not jam because everything is working correctly. if you could find the problem, it may be quite easy to fix. my wifes gun had a burr on the extractor. most of the time, it would work. but as the shots fired climbed, so did the f.t.e. count. a little gun scrubber, and a small screwdriver at the range helped me figure out what was wrong. once we got home, and i looked at it, 10 minutes with a polishing stone took care of the problem permanantly. it may have eventually worn in. but who wants to chance that.
