Is there a way to adjust the amount of air expelled each shot (to change the velocity) of Walther LPM 1. My pellets are tearing the target and not making round holes. I suspect low velocity until I prove it on chronograph (I need to borrow).
Thanks

Velocity Adjustment
Walther LPM 1 is a single stroke pneumatic air pistol, I don't think there is a adjustment screw like some compress air gun for velocity control. instead, the velocity is product of how much air is compress into the compression chamber and the condition of the seals
If the seal on the compression piston is wore out and if air is leaking out of the compression chamber before trigger is released, low velocity will result.
Check the condition of the items mentioned above, clean, ligthtly lubricate or replace them if required, however the LPM 1 is not a pistol able to shoot into 500+ ft/sec, due to the limitation of the short compression lever, one belong to a fellow club member in excellent condition usually shot 420ft/sec or so, check the velocity, if its in the low 400 ft/sec ballpark, I don't think there is anything wrong with it.
If your pistol turn out to be OK, you can switch to a lighter pellet; use better quality targets; or place a piece of card board with the center cut out behind the target to give it more support for a clean cut shot hole.
