Hmmm. Dunno.
I apparently already own more firearms than I can keep clean.
I also own enough 'working' handguns with which I've trained & qualified that I could carry a different one everyday and not carry the same one off-duty for almost a month.
The several handguns I picked up within the last couple of years were basically last minute decisions without a lot of planning or 'need' involved.
That said, I still have a few others on my "If I come across them sometime" list ... such as a M40 nickel finish and maybe a M&P 40 compact (to basically permanently 'retire' my G27).
I'd still like to refill my revolver collection with a couple more Ruger SA's and maybe another K/L frame .357 or two, as well ...
I might even add an AR carbine to my collection to complement my Colt HBAR if they're still lawful for purchase when I retire to another state, although they can be expensive to purchase as an individual. Feeding them isn't exactly inexpensive, either. I also wonder about being able to find someplace where I can continue to realistically train with one once I no longer have access to my agency range. Pretty low on my list ...
I really need to get another gun safe, though.
