I grew up shooting a 20 gauge semi-auto at clays, pheasants, ducks, quail, dove, etc...
When we got tags for sandhill crane, I fired off a few 3" shells from an 870, and the recoil was significantly more (obviously), but I don't really have a frame of reference to compare that to the standard 12.
Appreciate the advice on 3.5" shells anyway...I'm a little surprised by the overwhelming response that they're too big; more almost always equals better!
However, I missed the window on this buy...I'm not one to buy w/out having a good understanding of the market first, and I'm sure I'll be able to find it at this price again before too long. It was only discounted ~$30 anyway, and I haven't even shopped at my favorite guns only shop yet, who seem to undersell everyone.
I spent a little time last night looking for other options, and it found a comparable high capacity shotgun, the Mossberg 590 which comes w/ a 20" barrel (instead of the 870s 18"), and has room for one more shell in its magazine.
I believe mag extensions are available for both, yes?
And both can be afixed with a picatinny rail or a flashlight mount?
