Hi all,
I stumbled upon this forum and thread whilst looking for a tuning kit for my LP-53. It is my second LP-53 (after foolishly selling the first when I was a teenager). I have had the gun for 20+ years now and it is in good but not mint condition. Although I also have a HW45 amongst other things, the LP-53 is still my favourite pistol.
It performs well - I typically get 410 fps with 7 grain hobbies - but would still like to get that extra bit of power for shooting at over 10 metres.
I found another posting on the forum where a gentleman managed to use the tuning kit for the Walther clone Predom Lucznik:

I ordered the kit for the Lucznik but the only real advantage was that the Walther now shot a lot smoother, which could be attributed to a sub-300 fps muzzle velocity, so it was back to square one.
So I am very interested in the modification done to John's Walther. The AGW article wasn't very specific so a more detailed "recipe" would be highly appreciated.
I can see that a Cometa spring is mentioned, although not which Cometa model or what length it had after it was cut down.
I also found this piston head assembly, which obviously would modify the internals further, but am unsure if any further gain would be had:
