I have been shooting the M2 off and on and doing further comparisons and have had an about face on my first, off the cuff, rebuttle on the Benelli recoil.
I think I had my expectations WAY too high at first and was surprised at the recoil and was very discouraged on my first experience with the shotgun.
After more firing and shooting clays, I have changed my mind on this shotgun. The recoil is more than a gas gun like the 1187, but it is a different type of recoil. It does kick, but the kick isn't a painful, hurt of a kick like other shotguns. I shot the 1187 again with turkey loads, 2 ounce, and compared the two. The 1187 didn't kick as bad on the part of moving my body back but did "hurt" more on the cheek and shoulder as far as felt punch. The M2 seems to jar me more, but it is a softer, gentler punch. No pain on the cheek or shoulder.
I shot about 50 1 1/8 ounce loads at clays and absolutely LOVE the way this gun shoulders and shoots. At the end of the day, I ran 10 more 2 ounce loads through it at clays and it did kick pretty good, but didn't to the point that I couldn't hit the doubles three times in a row.
I did purchase a C&H Mercury recoil reducer that screws on in place of the forearm cap, and it does help with the recoil of the turkey loads very noticably. I shot several rounds with and without it in place, and it does work. It definately isn't needed on the 1 1/8 ounce loads, but does keep the muzzle down and soften the punch.
I regret "jumping the gun" on my original post and do retract my first opinion on the gun. For those looking for a soft recoiling gun due to injury, etc. , you probably want a gas gun and a 20 ga. at that. My dad had shoulder surgery a few years ago and can't take the kick of a gun much at all. He wouldn't shoot it when I first bought it, but did at the clays range the other day. It kicked him, but he said it didn't leave him sore or hurt like he expected. He bought a Rem. Sporting 20 last week for doves and maybe even turkeys due to his condition and it is a dream to shoot for sure, but he said he was surprised at the M2 on the way it didn't "hurt" his shoulder.
Sorry for the rash review I gave. I am now a true Benelli fan. Great gun and I can't wait to use it in the dove field and elsewhere.
