Cap pistol...preferably with a holster. Practice your fast draw as on TV westerns...the other person being a bad guy of
some sort. Both of you had the moral obligation that if your cap pistol didn't "go off"[a little puff sound] first it meant
that he had won the draw and you were supposed to drop to the ground...near death and with much agony as possible.
The little roll of caps you put in your pistol had maybe 6 shots.
At least in my neighbor hood having double holsters and 2 cap pistols was somehow beyond appropriate and too
farcical for those of us who in fact were deadly but righteous gunslingers.
