Chrono numbers when a 95 was shipped to me.After more testing with a variety of JSB's I sent it back .

Hard not to hear the ram/spring slam on the end of piston when your holding a gun near your head. To the shooter you wouldn't notice a difference.
That is something I was afraid of happening as I won't have a way to test it because I don't have a chrony yet. Did you get another one? If so, did it have better numbers?
