RE: Which pump shotty??
I purchased the 12 ga. 870 Express Magnum combo package in synthetic last fall. It came with a 23" rifled barrel with cantilever scope mount, other barrel is a 28" smooth bore. I mounted a Nikon Pro-Staff 2-7x32mm shotgun scope on the slug barrel. Price was $428.00 for rifle combo + $125.00 for scope at Gander Mountain. I shot my first deer ever at 110 yards right through the heart with Hornady's SST slugs. The factory barrel is very accurate! After sighting in at 25 yards, then at 50 yards at the rifle range, I actually hit dead center of the target bull’s-eye at 100 yards on my first attempt.
I also took it trap shooting a few weeks back and used the 28" smooth bore barrel. It wooked out great. I was also surprised to see that one of the trap shooting instructors had the same shotgun as I have.
All in all, I am very pleased with the whole package (including scope). Great value, good products.
