Can anyone advise how I can convince an out of state seller that a GI M1 Carbine (clearly a C&R) is not a "Regulated Firearm" in Maryland? The problem I am running into is the "Auto-Ordnance M1" that is on the Regulated Firearm list, which I have always understood to refer to an Auto Ordnance Semi Auto M1 Thompson. Unfortunately Auto Ordnance no longer sells M1 Thompsons (concentrating on M1927/28 clones), but does sell the Kahr M1 and M1A1 Carbines. I have never run across a local seller that believes that M1 Carbines are regulated, but I can see how an out of state seller might have qualms.
