You might consider getting a set of TOTW nipples or Slix Springs. Then you could go with either the #11 caps or 10's whichever is available.It’s just the opposite at the Sportsmans warehouse where I live. First of all, they never carry any caps, but the guy told me I could get them delivered there if I order them online. When I looked online for sportsman’s warehouse, I didn’t even see number 10 caps. All I saw was number 11.
My son was able to pick up some number 10 CCI caps in Texas for me. I know they fit tight on the nipples of my pistol but they’re better than nothing.
