Yeah, the Carbine's effectiveness is pretty silly. It deals more damage than the Garand per shot...
I have a Garand too, but not a Carbine! Love that rifle.
I’ve got one of each of the mainline rifles from the war, and it’s silly how much better the M1 Garand is compared to everything else. Better sights, faster loading and eight shots instead of five and I haven’t even mentioned that it’s semi automatic yet!
My M1 carbine is a fine shooter too, I highly recommend getting one if you can. Original USGI ones can be expensive but a the IMI carbines made in the 90’s are a great facsimile. Mines a 1943 production National Post Meter but I got it cheap because it had a scope mounted on the side which had to have the holes filled back in, so it’s not a perfect collector example, but it shoots great and I was able to hide the damage under a new stock.
