An oldie, 10" factory octagon .45 Colt
It's on Doug's Reeder flatside'd Contender. What a thin barrel muzzle! I think you could dent it if you dropped it right. It feels too light but I weighed it and it runs 40 oz. w/o a rear sight, that would add about 2-3 oz. It needs a pound of scope and mounts at the least!
Not sure what he's intending to do with it.
