Well I'll just touch the high points. Disclaimer: the Folding Remington stock is only for transport in a vehicle! I would normally never use the gun with it folded and would not shoot it for long stings! . I am embarking on a project to shorten a Rem folder down 2" and put a gell pad and cheek rest on one. It will be a fun TIG project!
Any way the folder is my old 60's Wingmaster Magnum that was "Robarized" in 1987- early stuff! It is VERY slick with around 10,000 shells thru it since Robbie Barkkmann did it. It is now the stand by gun being replaced by the 1989 Police Magnum for classes since last year. The Police Magnum has my new fat profile 18" RS Imp. Cylinder barrel with AO nite sites.It has a 12" Houge stock with a 3/4 pad(thats an 1 3/4" of pads!!!) which is perfect for me and the pad gives me a nice cheek rest. The foreend is a "handicap device" from the 80's which allows one to whack the heck out of it if something sticks. Also provides a positive return!The light on the Police gun is a Surefire KL-5 in Vltor mounts. I like being able to take the light off during the day training! The single point sling on a GG&G adapter is a Specter MOUT, the folding gun is a Wilderness sling, notice how it could foul the pump ect. , which is why I like a single point. The side saddle on the folding stock gun is my own modifacation. The police gun has a Vang safety and the Robar has a Williams big head.
Because of the single point sling the gun when moving is flopping around or requiring a hand to hold it to body; that there is a Mad Dog labs experimental 870 belt clip. You just slide gun straight into the cross draw position 'holster' and it snaps into the kydex so it doesn't flop - NO hands reguired to hold gun now! And holds the 18" gun just high enough so you can kneel (at target butts!) with out hitting the barrel on the ground and stock on the gun is below your vision!
