[others] GnP GBB mag VS WA GBB mag

Hi,

I used to use WA mags and the performance was quite good. When I use GnP pmag instead, I do realize it is kind of weak (bb velocity is very slow and recoil is significantly weaker) , seems like the "hammer" doesn't hit the mag gas pin strong enough. For those who have experience with both brands, I just wonder should I "twist" the trigger spring so it would have stronger force for the pin when I use GnP pmag?

p.s. I'm using prime lower receiver kit, prime steel bolt and GnP "airplane"

Thanks a lot!
