increase pellet speed

[eduardo zamora]

I have some problems with the speed of shot of my gun FWB P30, I want to know if I compress the spring of the hammer, using plane rings, I can increase the speed of the pellet.

thank you

There is an adjustment screw for the tension on the striker spring. One thing to note that changing the velocity may very well change the grouping of the pistol. This work should be done where both a chronograph and a 10 meter range are available so that the grouping can be checked.
