Smith n Wesson 357 is my favorite to shoot around, but I hardly ever get it out of the safe. My favorite that I shoot often is my Ruger AR 556, i shoot it every chance I get, but it’s been about a month since I’ve had it out. Shooting clay pigeons with the Ithaca 12 gauge dad gave me when I turned 13 is a lot of fun too. Now that I think about it, I’m not sure I have a favorite. I love them all equally for different reasons
Rifle: 1942 M1 Garand & Yugo M48A
Pistol: WWII Walther PP & 1936 P08 Luger
Shotgun: My Dad's/Grandpa's Parker
Finally...IMI UZI Model B (I have several barrels if I SBR it...)
Mine would have to be a Nylon 66 Apache Black I bought years ago. It has to have had about a quarter gazillion rounds through it by now. I taught my daughter and son to shoot with and memories like that still make me smile every time I take it out.
My mid-sized collection is fun to shoot and I cycle through the entire bunch regularly. But I can break out three: For handguns it’s my S&W 686. For rifles it’s my M1 Garand. For shotguns it’s my Browning Citori.
Having fun shooting. Now here is an idea I can get behind. I'm best, and quickest with an AR. It's what I did for so long as my job. It's what I did on deployments overseas. It's what I practice a lot with still. It's what everyone seems to be infatuated with because it's "cool" or they have fantasies of going to combat themselves... Nope... Oh I like shooting my ARs ok, but just ok. To me they are work guns. When I want to have fun, I want to work the action myself. I want to cycle a bolt or lever.
To me, the most fun gun I own to shoot is my Rossi 92 in .44 magnum. I had the 24" octagon barrel shortened to 17" by AllenM. Then a leftover piece pf picatinny rail found its way to the top flat on the barrel. Now a Sig Romeo 5 sits there, along with a light mounted in a Thorntail mount. Steve's Gunz provided the rear peep sight, and large loop lever, and I got rid of that pretty to look at, but painful to shoot curved metal buttplate in favor of a recoil pad, and this thing is a dream to shoot. It's a great deer gun, home defense gun, Jeep gun... It's just plain fun to shoot.
