Hey Guys, I got a cheapo mount from Dealextreme for my 870, and it seems like it's going to do what I want if the placement is OK. It's mounted directly to the barrel and not the mag extension; will that be a problem? I like where the flashlight is located using the mount, (old school Surefire 9Z with a LED upgrade), because I can access the tailcap switch with my thumb. If I want momentary use I can press the switch, or I can just roll the tailcap with my thumb for constant-on. The mount works perfectly with the cut-down section of the 9z and with the dia. of the barrel. The dia. of the extension is bigger than the barrel and I don't think it would mate as well with the clamping service of the mount, so hopefully it won't be a problem. Let me know what you think and I appreciate the info. Sorry for the crappy 3g iPhone pics... Happy New Year!
