So recently I completed my search for my new shotgun, nothing particular special, a browning auto 5, 16ga, looks like it has an adjustable choke, but kinda run of the mill, it's seen some wear but over all in good shape, pretty much everything I've been looking for except that the barrel is a bit longer then I would like. I was curious if anyone knows what it might be worth? I was thinking of having a few inches taken off the barrel, would doing that devalue the gun? Or is this something that would be worth keeping original? With this gun having a seemingly adjustable choke,does that mean I'm still able to fire slug ammo out of it? I can post pictures of the choke if that would help.
