    Default Roll Pins

    The roll pin for the Mag release on my P30 and SK move in the hole, and begin to come out of the frame. HK recommends replacing them as you remove them, but although I never took it out, it’s still moving.

    Does anyone make a better, aftermarket pin for HK pistols, or are the OEM roll pins the only option?

    Other people have had problems with roll pins. If a new roll pin doesn’t fix it I’ve heard a drop of loctite fixed it.

    My P30’s are fine but my P30SK I readjust/push back after ~300rds.
    HK uses a roll/split pin here, a suitable design given a poly-slot/metal-pin condition IMO. The ‘problem’ is the split pin only has 2 points of friction/tension + a poly/slot bearing surface = hold/retention is compromised.
    Then there’s the use of use of (penetrating) oils, maybe the next time I’ll use a new pin after degreasing both slot/pin.

    I’ve heard of the Loctite, but I’ll need to search if it helped. Loctite works on threads, threads increase bearing surface, the thread are isolated, Loctite jams/locks the threads when cured. On a pin/slot, there’s no place for the Loc compound to set up.

    You can also slightly expand the roll pins if they're loose. Put it half way in a vice and then tap at the end with a scratch awl and light taps with a hammer. Retry regularly to ensure that you don't over expand it.

    Thanks, I’ll try the Loctite and see how it goes.
