So I  recently switched to G series from my 1911 , I bought used m19 seems to work fine but it is used and unknown amount of bbs thru it..
I want to give it a tune up , I have upgraded recoil spring already any other recommendations on parts I should replace??
I am noticing on last 2 shoots I seem to run out of gas not sure if it gas getting to cold or something else?
thanks
