Hi Nick,
That sounds ideal, if you've shot my Venom Ultra glide you know that's very quick due to the alloy piston, a similar result to yours I suspect.
Iirc it had the shortest lock time from those tested in the tests done at the bash with the resonance/recoil rig.
I have had people say it was too quick for them, but minimising hold sensitivity is the goal for HFT as long as accuracy is good with no fliers or fps variations.
Cheers
John
