    Is there a source anywhere that gives the sizes of standard factory springs for springers?
    Length, OD, ID or wire thickness, number of coils.

    I had a feeling there might be a post on here but I can't find one, only the pinned thread with the Titan springs.

    Failing that, what's the standard for LGU springs and HW95 springs which seem to be popular for aftermarket tunes of the Walthers

    Thanks for the info and the link. I knew I’d seen a thread somewhere but I’m not on there much these days.

    A TX200 Mk.3 mainspring and a 3mm transfer port go very well together in the LGU, Adam. The 2.9mm wire necessitates a wider spring guide, though.
