What is the difference between #10 and #11 caps?
#10 caps have a slightly smaller diameter than #11 caps. They are most commonly used on cap and ball revolvers (like Colt or Remington replicas) to ensure a tight fit on the nipples, preventing the caps from falling off during recoil.

My experience is my Piettas use 10s, and my Ubertis use 11s. I pinch the 11s just a bit if they need to be snugged up. Pro tip: use a wood dowel or pencil eraser to push the caps on. They probably will never go off while putting them on, but if one ever does your thumb will never be the same.
