I personally love a well built 1911 if we’re talking all time favorite, even though I don’t care to much for a .45, nor have I ever owned one. Might go down the rabbit hole one day and get a RIA 1911 just because of the price point, and to play with the grips and what have you. Honestly couldn’t see my self shooting it that much.
My favorite that I’ve personally owned is an IMI Baby Desert Eagle .40 cal (wish I still had it)
My favorite that I currently own is my .380 Beretta Pico, mainly because of the amazing concealed carry options and EDC in general, as well as some sentimental reasons and history I have with it . I can honestly say it is 1 of maybe 3 guns in my entire collection that I will not part with. It’s nothing crazy special, but man I love that little ol gun.
