    I just received from Pylinski Arms the kit of gas springs for my beretta A390

    So now I have 5 springs colors

    Yellow
    Purple
    Blue
    Red
    Green

    Can anyone give me an idea which one will work for lite target loads?

    Ronbo,

    You should have a list of the strength of each spring in pounds. Basically, you want to use the strong springs for light loads and the light springs for heavy loads. Ideally, the spring you use should throw your empties about 6 feet from where you are standing.

    Let me know if you need more details.

    Use the spring with the heaviest or thickest metal for the lightest load. The idea, with light loads, is to keep the system which bleeds off gas closed longer to make sure there is enough gas to run the action. With heavy loads, you would use a light spring which will compress more readily to bleed off gas not needed to run the action. So, trust the above; light spring heavy load and vice versa. If your empty goes more than 6 ft, put in a lighter spring to bleed off more gas out the forearm vent; your action is opening with too much speed.

    I thought that it was the opposite. That you wanted to bleed off as much of the gas pressure as possible, to just make the action function. Am I correct or incorrect. This would reduce recoil???

    Try blue.
    It should be the next heavier poundage from factory.
    That is the one I use for coles springs on a 1 oz light recoil reload running 1180fps.
    It will cycle doubles fine.
    If shells don't eject 6 ft from action then red.
    Green should be for 7/8 oz. light loads.
    You should contact Pylinski for the poundages.
    The Coles Website may still have the info up.
    I havent' checked in awhile.
