yup... I guess you go from "needs" to collecting of some sort, or move on to semis, shot guns, or rifles...
a couple things I did when my "needs" were met...
yup... started collecting...
how many different calibers...
antique & C&R revolvers... top break, solid frame pre loading gate, bottom break, black powder cartridge, etc. ( I have about 3 dozen of these in various brands & configurations )
specific purpose use... target / bullseye, cowboy action, etc.
