I've been looking at the Border Patrol model. The new shotgun price seems a bit excessive to me. Does anyone have an opinion on the Retro-Fit Customer Supplied Shotguns? $460 as opposed to $735. The only 870 I have is a 20 ga. Even if it were a 12, I wouldn't send it in for their Rem Steal b/c I use it for hunting. I'd have to put in a couple plugs to take it duck hunting then, haha.
