Some feedback from this post, wherein Reader Brad_In_IL solved his “What pistol-caliber carbine to buy?” problem:
Brad writes: “Indoor. Off hand. 50 feet. Need to get a sling. First shot was the head shot. The other 24 were insurance.”
Amen. Adding a well-adjusted sling to the mix would have resulted in a single palm-sized (or smaller) hole for the 24 insurance shots.
