Sidearms & Scatterguns STI Mag Setup

[CaptRob]

I received my 126mm tubes, Grams 11 coil spring and followers, and Dawson aluminum tool-less base pads. I know the Grams kit will work with tubes up to 145mm so my question is, should I trim the spring to allow for one more round or should I leave it alone. Grams said I could trim the springs down to 9 coils.

Beven is definitely the man when it comes to SV-STI mags so if he says you can do it then it's your call.

I have always been a fan of just trying it out first then cutting it up! but when a person from a place like Grams says you can do it...Id bet my money that it works great!!!
