TM P226 Hop Up

[Sgt Rob]

Hi all,

Just upgraded my TM p226 with metal slide, recoil spring, loading nozzle, piston head, nineball mag routers and hop up bucking, and high flow mag valves. I've been test firing it with 0.43's can't seem to get them to hop up even with the hop up spring slightly bent, it'll hop up 0.2's. What ammo have people been using in there upgraded standard p226's?

I was that i used to fire 0.43's in my standard high cappa and it was hopping up no worries.

any ideas??
