I bought a CZ 75B with the intention of threading the barrel for a SWR Trident 9, and also picking up a threaded Kadet kit. I bought an 870 with a pistol grip with the intention converting it to SBS. I'm looking to put a stock on it now though, still will do the SBS as well. If I had a bunch more money, I'd look at doing an intregal silencer on some cheap 12 ga pump. I'd likely have to make that one myself though.
