I don’t have much sentimental attachment to my guns, except for a chosen few ( guns I brought back from Afghanistan, my dad’s colt single action, a shotgun my brother bought me for my 14th birthday - legal age to start hunting where I grew up)
I accumulated a ton of stuff when I was younger, but over the years decided to cut loose a lot of stuff and stick only to the guns I actually use.
At one point I had multiple examples of 9mm’s from like 8 different makers at one point.
The cobra 22’s especially a 3” are something of a rare bird and definitely would bring good money at auction ( the best way I have found to get top dollar even with the auction house taking a cut) if that money can then be sued to get something you would use and enjoy so be it.
A few years ago I got bit by the precision 22 long range bug, and collected about 5 or 6 guns I didn’t use much that got sold to fund a full Kidd super grade build with quality optics, and I use that rifle a lot, and don’t regret selling the 6 or so others to make it happen
