About of both
I had to fit a new trigger on mine to stop it pulling ATB Dan
instead of doing stuff to smk's you'd be better off buying a decent springer , weirauch,air arms
That's why i got rid of my one and bought a crosman nitro venom dusk, not an amazing springer but much better quality than my old smk, only paid £300 but it's my second air rifle so I didn't want to spend loads, ATB Dan
If you paid £300.00 for that gun Bro you was done. there are many better guns out there for that price.
