Aftermarket RSA Spring Fit?

    I put a low weight Wolff spring on a Jager polymer guide rod and the spring kinked like a snake. Everything should be gen 4 unless it got mixed up. Any ideas why the spring kinked like that?

    Spring is too long, or the diameter of the rod is too small.

    Assuming you ordered the correct spring, and since you are using 2 components that were not designed around each other, I would conclude that the rod is too thin for your spring.

    A ISMI spring may be better suited for your rod-- I would call Jager before ordering any more parts.

    Wolff Springs are a larger inside diameter, and do snake on the guide rod. This does not affect performance at all, and many shooters prefer the Wolff springs over the ISMI.

    Also, keep in mind that the spring cannot snake as much when the RSA is sitting in the channel in the frame when the pistol is assembled.

    How does it perform?

    Thanks, jager

    I was thinking the same thing.

    If you consider other perfectly reliable firearms where the "snaking" of the recoil spring is normal (AKs, Tokerev, Armalite 180, 1911, etc...), you only notice the "snaking" because the Glock stock RSA is so finished looking .... it is, after all, an "assembly".

    Then there is the FLAT vs. ROUND spring arguments.. :lol::rofl:
