Ruger PC Carbine Doubling

<I wish Les were still here>

Last year with about 500 rounds through it my PCC worked fine.  For some reason it’s sometimes doubling.  Same ammo, no upgrades SINCE last year.  Not finding anything on the forums.

Doesn’t seem to be my grip.  I’ve thoroughly cleaned it, no joy.  I’ve taken out the TK flat trigger and put in the original, but haven’t tested that yet.  I used it with the TK last year no problem. 

Any thoughts?  To little after travel?  Too much?  Should i swap out the hammer?

How much travel is in the reset of the TK trigger?

See what happens with the trigger replacement.,
