Any chance of a pic of the piston? (Always take pictures from parts before making them unreachable)
Also the piston diameter seems very very close to the porting. This is only recommended when your piston is very tight and your pilot valve is near overkill, because this way the piston opens very late, and more air may leak out of the pilot volume before it snaps open. However, if your piston is very tight and your pilot valve is good, a "snapping" piston gives a faster opening and possibly less bounce due to the pilot volume being at a lower pressure when the valve starts opening.

The piston weighs 1/2 oz.
