Hey guys and gals,
A few months ago I was out shooting my 135 in .30 and it was smacking hard. Infact I cronyed it right around 520 FPS with a 44 grain JSB. Resently I shot it across the chrony again and ended up with 235 FPS.
Has anyone else ran into this problem? I've lost a lot of power and the cocking effort and trigger have gotten extreamly easy.
Thanks for any help.

The 135 is a gas piston rifle so no broken spring.
sounds like the gas piston is leeking. Probably need to contact Hatsan
The 135 is a spring gun, the 135QE is a gas piston.
You are correct !
I did not know it was offered in a spring... I could see owning one of them.
in the mean time I will be over hear in the corner.
well in the long run it will have to come apart no matter what powers the piston
you might take the stock off, if not already done and see if you can see any spring overlap
here is a good place to look at parts diagrams and they 5-135's listed but only 2 have part diagrams
