So I had the Original AVA Tactical mount and had bought an Elzetta light to use with it. Got a good deal on the Elzetta on FleaBay. First time went to shoot the gun, the Elzetta pulled the ripcord and easily escaped it's restraint. The mount would not hold that light. Probably could have used some InnerTube material and got it clamped down, But I would have always been suspicious of it. Stranger Danger steered me to the Impact Weapons mount. Still needed another light though...
The Surefires M600DF looked nice but High $$$. told me a while to make that leap but I just did and I have to say, they make nice lights, and strangely lightweight for their size. Glad I got it, never owned a Surefire before, now I kinda get why people like them.
The Elzetta weighs 5.9 oz. and the Surefire weighs 4.6 oz., so that's a good thing saving 1.3 oz. SF is a little longer which will help with unshrouding the light a bit, the Elzetta threw a pretty big barrel shadow.
Also, the Surefire ran 3 hours on the 18650 Battery that came with it, amazing!
The Impact Weapons mount is really light and get's the job done perfectly, low drag as well compared to the AVA mount.
The Impact Weapons folks extended the combination discount for the Surefire/Mount combo even though I had bought the mount quite a while ago. Thanks Earl Pitman for the discount after the fact! He seems to carry his phone around and answer it 24 hours a day, 7 days a week... With the discount the light was like $5 more from Impact, but I think those $ went to a good company for sure.
StrangerDanger turned down the SureFire Switch for me and everything is ready to mount up now. Nice to have SD as my personal Gunsmith!
I'd like to say thanx to everyone who helped me out on this!
