The SP10 has been the most unreliable shotgun I have ever used.
I had a ton of problems with shells hanging up in the mag tube, until I pulled out the follower and went to town with a Dremel on it in an effort to widen its clearance with the tube and keep it from hanging up.
My rub with a ten gauge is that fact that it doesnt do much more than a 3.5 12 and it weighs a bunch more,ammo cost more and is less available.
The last few years I have been shooting Black Cloud 3" #3 out of a Benelli SBE and have gotten better performance in most conditions vs. the sp-10.
