Was in Firing Line yesterday; can't speak to the carbine discussion because I wouldn't know one if it fell on me. However, even though they were busy and had literally NO pistols except Kimbers (interesting), they were very pleasant and even came from behind the counter to help me with a purchase. They also scrapped up some .45 Federal SD ammo. Have gone before and will go again. Be advised: they really don't have but 15-20 pistols left, though they DID have a really nice ATI 3" 1911 for under 500.00$. Incredible times!
