If it checks out, that's a can't lose proposition. Is it a half lug or full? Bonus if 1/2 lug IMO. Good deal regardless.
He means the lug underneath the barrel that houses the ejector rod only goes halfway down the barrel instead of being flush with the muzzle. Being a half-lug means there is less weight out towards the muzzle and makes it more maneuverable. The extra weight if it was a full lug would help lower muzzle rise.Can you elaborate on that? I've got a 4" GP100 I used to shoot a lot in my early 20's but don't know a lot about the guns.
