Pff already some time back, I try.
Gun recalls with a push instead of muzzle going up. This is the most remarkable thing.
I was able to shoot a Xmas tree faster then ever before (though I had to get used to sight picture, fs looks low is you are used to Shadow 2 etc.) this was with factory S&B 124 gn ammo so quite hard..
+ Grip is amongst the best ever, liked it, lot's
+ Trigger is good and was set at 3 lbs for production class (factory can make it lighter / heavier) break was crisp, liked it.
Most shooters who tried it cam back from training area with a big smile.
Hope this helps.
