This may seem to be a strange question, but has anyone tried to reduce the power of a Beeman P17 or similar precharged pistol ? My wrists aren't as good as they were (Arthur Ittus) and the last bit of the compression stroke is hard work and painful. I thought about drilling an extra pivot hole in the piston shaft, slightly nearer to the piston head. This should increase the volume and reduce the pressure of compressed air in the valve system. Any thoughts on this?

I have an HW45 and 75. The 45 even on full power is easier to cock. I agree a 45 on the half power setting is probably a good option

I decided not to try moving the piston pivot hole. Instead I drilled a 2mm hole in the top of the cylinder, 4.5cm from the front end and carefully smoothed out the inside of the hole. The piston then only compresses air after it passes this hole. The cocking stroke is now much easier and the power doesn't seem to be much less. Accuracy is the same, and the pistol still knocks over cans at 12 metres. If I want to go back to the full power setting, all I need to do is cover the 2mm hole with some self-adhesive aluminium tape.

An interesting and good way of solving your problem. Thanks for sharing.

And there's been a quite interesting mini-series going on on the PyramydAirBlog on the P17 for those interested.

Cheers for that, Geezer.
I'm hopeless with these computery things and unable to do links.
Incidentally, there's what looks to be a nice and realistically priced HW40 in the Sales Section currently.
