    I got my Rohm shooting smoothly at 4.7ft/lb for the price of a few M4 washers.
    If I took it above this, it started to fluctuate a bit, and muzzle flip started to creep in.

    It's all logged here;

    Hope this helps.

    It can be done with minimal fluctuation, I run one of mine at 5.2 ft/lbs for HFT Pistol and general knockovers, muzzle flip doesn't seem to be too much of a problem either
    Just packing the spring to achieve increased power can cause problems though, increasing the reg delivery pressure and adding a helper spring which has no pre-load can result in a very smooth shooting, full power pistol that's still useable in double action with the 8 shot mags

    Sounds like it's usable for our Police Pistol comps: upgraded or not.
