I have a Limbsaver on my 870. Tames the recoil a bit, but recoil is still not pleasant. The Compstock and the Limbsaver both claim to cut recoil reduction by 50%. I want to buy a new stock with a sling stud for my 870 Express. My existing one doesn't have one (it's a black synthetic). I can probably a Remington stock with a sling stud installed for about $75. I THINK that comes with a Remington R3 pad, which I have heard is identical to a Limbsaver. The 870 Marine Magnum I saw today has an R3 installed, and it says "Limbsaver" right underneath the "Remington" logo. The Compstock has the spring system in there, but I have to drill a hole for a stud. I had the Knoxx Spec Op once, and I got cheek slap with it. Is the Remington stock with a Limbsaver pad just as effective at reducing recoil as a Compstock is? I'll spend the extra cash if it lessens the felt recoil. I'm a big guy, 6'2 and 235 pounds, and the stock is firmly in my shoulder pocket and my stance is forward, but shooting a 2 3/4" slug out of the gun makes me never want to do it again.
