I've been running a Herrington HC320R Comp for some time now on my Flux, but decided to try Kaw Valley Mach 3 Linear Comp which has lived on one of my PCCs.

Does anyone run Mach 3 comp on their P320 Flux Raider? Did you have to change the recoil spring? If yes, what was the spring weight or did it run fine on the stock spring? For ex. Herrington comp required a 14 lb spring with 124 gr ammo to run reliably.

Thank you in advance.
