I have an oppertunity to trade for this M1 carbine. It was bought from CMP,and arsenal inspected and /or repaired. Seller says it is in good condition,Underwood receiver/barrel stamped 1/43 with bomb marking.
Comes with 1 mag.

I have offered in trade a SigSauer P229R .40cal. that I don't hardly ever use as it does not fit my hand correctly.

Is this a fair trade? Would you shoot it or would it be a safe queen?
What would you do?

Thanks.
