My dad showed me how to tape two 15rd. mags together for my M1 carbine. When I’m home I hit the range and practice swapping them around. At the price of ammo these days and also the availability I don’t shoot. I do have a Crosman Benjamin Trail NP .22 Caliber Nitro Piston Air Rifle and can get all sorts of shot for it. Some go as fast as 1200fps.
The M1carbine is a nice little weapon and a nice size for home protection. When I was in Nam it and the M2 was popular with Arvn and Montagnard troops due to size and weight. Later, they transitioned to the M-16 as it became more available. I don’t have an M1carbine although I would like to own one; maybe a Rock Island or a Singer would be nice, lol :) I do have a Ruger 71/2” Blackhawks with scope that I use sometimes for pig hunting though. I recall shooting once shooting a javelina with it at about 20’ right between the eyes. The shot knocked the pig down and after a few seconds that pig jumped up and ran off into the brush - much to my surprise! Point being, irf you have it for home defense and should have to use it someday, be sure to put several rounds into the perp and if hr goes down, stay alert and on your guard, don’t assume that you finished him off because he might just get up after a few minutes....
