It's very personal and relative and I support folks wanting to own 10, or 100, or 1000 + if it brings them happiness. I got up above 15 and realized it was too many for me to enjoy. I had to decide, am I a shooter or collector ? I'm a shooter. So, I am selling some now. I try to think of what role a firearm plays. I have a few "because"- I like them, the way they look but make or break is the way they shoot. "never sell a gun that shoots one hole". This made me keep a cheap gun over a more expensive one. I'm most about performance. I have one or two I wanna buy and 2 or 3 still to sell. All of my collection at one point fit into a suitcase! As few as maybe 7 years ago. Lord willing I'll be able to hang on to the ones I have now and pass them on, and make a ton of great memories along the way. Don't think I CAN get below maybe 12 anymore.... That is a lot I think for non gun folks.
