maverick 88.
avoid the mossberg 500 as well. ive shot 2 different ones, that the shell stop had failed on me. the 20ga wasnt a big deal as i was skeet shooting, but the 12ga i couldnt get off a second shot at the deer i was aiming at. heres what happened both times
1 in chamber, 2 in tube. take first shot. pump the slide, slide stop released the shell too early, so when the arm came down to get the shell, it knocked the live round straight to the ground, the stop caught the 3rd round, but when i racked the slide forward to what i thought was a loaded gun, i had nothing
now if this happened on my dads 30 year old gun, i can see that happening. when it happened on my buddies fairly new gun of the same model, thats it for me.
like i said, my 870 has never given me a single problem, and at the price they can be had, its hard to beat. maybe check out gander mountains used section. if you buy used, see what chokes they come with.
