I have been using my 1945 Inland as a replacement carbine for under 100 yd 3 gun matches since the OIC interfered with my original match rifle . It has its shortcomings, it is not as ergonomic as an AR, there are not many accessories for the M1 Carbine like mag pouches, initially brass is a bit of a problem. Reloading for it is easy with either FMJ of cast lead bullets. Cast lead allows me to shoot in PCC matches where the steel targets are not at long distance and minimizes ricochets'. I mounted a Burris Fast Fire 3 on it and I have had a hoot shooting it. Unfortunately on the last stage of first match the extractor broke, causing me to buy a second (1943 Winchester) "just in case" carbine if it ever happens to me again in the middle of a match. But then its a 77 year old gun. That being said I remember my extractor breaking on a 5 year old AR 15.
I'm long past the day where I go to a match to "win the pink Cadillac", so I'm not worried about coming in at the bottom of the totem pole. But I do get style points and have had many compliments on how flawlessly it runs. Hark, I hear that there is a M1 Carbine locally that needs some TLC, a 3rd Carbine could be in the future. Do I worry about another Liberal OIC down the road, NOPE. The current and a future Liberal government is going to screw legal law abiding gun owners anyways so I may as well enjoy myself while I can.
