Let me just toss in my two cents here. Last spring I bought a Rem 870 3 1/2" Super Magnum Combo. Nice shotgun, loved the fact it comes with a ribbed barrel and a rifled barrel!
Here's my issue. Most of the time I shoot 2 3/4" Winchester shells. I use them when I spot a grouse near the road when on the log trails up near the cottage (Minden). From the day I brough this gun home it wouldn't fire a short shot without jamming. There isn't an issue if I shoot 3" sabot or if I use deer shot through the rifled barrel, only if I shoot these "light" loads. I bought a box of 3" Kent and they went through just fine.
I've sent the gun to a Remington repair center up near Bracebridge, and it was returned with the note that the barrel had been reamed to allow for proper ejection. Seems that the shells (when hot, as in just fired) expanded and got stuck! The extractor isn't strong enough to pull them out, and I had to "pound" the butt of the gun on my knee (once I cleared the remaining shells from it) to manually extract the round. Yet, after it's first repair, it continued to perform this way. A second trip to the repair shop, this time I included the box top from the offending shells, so the repair tech may have the opportunity to correctly simulate the problem. The gun came back with a note saying they couldn't replicate the problem. Yet the gun still mis-behaves! I have several hunting pals as witnesses!
I will still use the gun in it's "rifled" form, as it's one of the best guns out their, but for birds (including Turkey!) I now have a Beretta 391 in 3". It's a gun I trust won't let me down no matter what the circumstance.
Good luck with whatever choice you make. As you see, it easily becomes one of personal preference as well as necessity.
Sell it and buy a Benelli, it digests everything!
