The high pressure piston was to fix a problem in some guns that when using compressed air they would leak like there was an overpressure in the guns. Most pistons are fine as long as there is a good paint barrel match and also depends on barrel length. If there is no leak out the back when you are shooting 300fps with your current barrel setup I would not change the piston. The piston is there so the gun will leak at over 300fps
