I have a thumbhole wood stock saiga 308, trigger is already is in the forward position, thumbhole stock feels right, going to leave as is. Also have a saiga 12 in stock configuration, going to leave as is. I already converted another of my saiga12's to pistol grip years ago and dont need 2 of them.
I did read somewhere, where the the stock saiga 12 shoots slightly faster then one with a G2 trigger assembly. Dont remember where I read it and I cannot tell you for sure.
