As someone who isn't a gun nut but was in the military, the size of the nutter's collections for their own purported defense is cartoonish. You can only ever use one gun at a time well, you only have 2 hands, and training yourself to reflexively lean into all the specific nuances of a single weapon within its class will make you far more dangerous than having a rotation of pistols, rifles, etc.
Using, training on, cleaning, a 92FS in my case until it feels like an extension of myself will yield better results than those yucks that use their 1911 twice a year, their Glock 17 twice a year, their 92FS twice a year, their FN five-seven twice a year, etc. It's fashion over function for those types.
