I might ask what your old shotgun was??
I use the Remingtons, ll00's or 1187's, not too expensive and tons of accessories, mag tubes, oversize bolt handles, oversized safety's, speed loaders and other loading devices, optical mounts, stocks, and easy to do trigger jobs, that come out to 2 lbs. In most matches the theoretical speed difference is not necessary as the targets are far enough apart to negate the differential between the speed of a Remington vs a Benelli or Beretta, and they shoot softer, if you want to shoot pump class I would still pick the Remington 870 for all the previous reasons. I do have a Benelli M1 Super 90, with a 10 shot tube, and the recoil impulse just throws me off, and the sight picture with adjusting the stock still does not get me on line with the target, and the trigger is very much like an M1 garand in concept , and is not light at all. Accessories are high, and not as ergonomic.
Just my 2 cents, but I have shot a lot of tactical shotgun.
Message me if you want specifics.
