Well, I have to admit that I bit on the STF 12 that the MSgt had for $800. It is very nice and like " Doge " stated, it operates just like an 870. Very smooth in it's operation and has some heft to it that soaks up shooting 3" slugs and 2 3/4" 00. The MSgt already installed a +3 mag tube to make it run w/ 7+1 like the SuperNova, and I tossed on a HoloSun to co-witness with the excellent GR sights already on the top rail. The only thing is the LoP is only about 12 1/2" (which is fine for squared-up shooting) and you can't access the magazine tube with the forend slid back. Going to blast more shells through it this weekend...
