WTT Taylor Tactical black brass backstrap for Canik Mete/Rival/TTI sadly doesn't fit my tiny hands, but really improves recoil management (~medium sized):

Looking for other Canik accessories:
Freedomsmith trigger
Lok backstrap
Small magno grip
Canik mags

Will also consider interesting CZ75 or 75 compact grips or CZ mags.

Might also consider select AR stocks, specifically magpul UBR or DD collapsible buttstock.
