I find that cappers are alot like nipple wrenches. YOu got to have a million of them. I have snail shaped, straight line, curved, brass, plastic, gravity fed, spring fed. Sheesh too da*n many. And each pistol takes a different kind it seems. Now for my Remington I have a dedicated straight line. Actually it's getting to the point I label or store wrenches, and cappers with the gun that fits it. I put them both in a nice white draw string bag with the gun info written on it in marker. Hey they only cost a few bucks each which is a pittance compared to the cost of the gun. Easy to grab when I go to the range or a civ war event, I just toss the bag into the range box or my backpack and go. It 's the same with the holsters. 16 guns and about 10 holsters. Some guns fit in some and some don't fit. So I label those also No more spending 15 minutes finding which gun fits what. And I won't even get into color of holsters- Some are brown (confed mid to late war) some are black (confed and fed) What a fun time we live in. Choices we have soo many choices.
