I've started to look into these recently because due to a recent injury, I no longer have full strength and dexterity in my “trigger” hand and the position required to hold the factory stock up to my shoulder quickly causes aching in that hand. A pistol grip would give a much better “fit” for my range of motion. Also, my shoulder was hurt, healed now but still a bit sore at times. But to facilitate easier (on me) shooting, I've been looking at recoil reducing stocks for my 18” 870. I use it as an HD gun, but also for general shooting/plinking. One in particular I’ve seen is the Knoxx/Blackhawk recoil reduction stock (http://www.blackhawk.com/product/SpecOps-NRS-Shotgun-Stock,1157,165.htm). I have heard a lot of complaints about “cheek slap” with this stock and am trying to get advice. I am 6’ and have slightly longer than normal arms if that is any help in the fitment department. I see they make a “powerpak” (http://www.blackhawk.com/product/PowerPak-Modular-Cheek-Piece,212,167.htm) for the gun that adds a cheek piece (the kit has a high one specifically for optics, I am talking about the low one see installed here http://www.rem870.com/2009/12/03/blackhawk-knoxx-powerpak-modular-cheek-piece-system/), but I am not sure how effective this would be or if it might affect sighting using the stock bead or possibly a ghost ring setup in the future. Also, with that recoil absorbing sliding motion right near your face, is there any sort of a pinch hazard or anything?
