Thread: 22lr light striking after trigger spring upgrade

Hi all,

I have a near new Hammerli tac a1 22lr semi auto.

I installed the light trigger spring upgrade kit, purchased from GC.
Rifle was excellent before that procedure, but I just wanted a lighter trigger.

However, now on a full mag, 9 out of 10 rounds misfire, likely due to a light strike?
When reloaded into the mag and fired again, most will fire after 1 to 2 strikes. Very frustrating.

Note: I am yet to replace the light spring set with the original 3 springs to see if that sorts it out.

Range is over an hour drive away, so asking here before I go to the range to experiment and take apart the exploding box of tiny springs which is the Hammerli trigger group.

Is there a way to keep a light trigger pull and still have a functioning rifle?

Can I replace just the original hammer spring to make stronger contact with firing pin, leaving the 2 light trigger springs in place? I imagine they are all balanced together, and not to be mix n matched?

Thanks in advance,
Len
