    Hello

    Just joined and am looking for help installing the mainspring housing retainer pin. It's all line up but she simply will not go in even with hammer blows.

    Welcome to the forum.

    Is this Main Spring Housing original to the pistol? Does the pin stop halfway thru the MSH or on the opposite side of the frame? Does the pin start at all in the MSH?

    Yes it's original and the pin doesn't start. It the correct pin and I'm trying to insert it in the correct direction.

    The original pin and MSH should allow reassembly so something changed. You possibly raised a burr on the frame or MSH or pin during disassembly. Just a few thousandths burr or misalignment could prevent the pin from starting.

    Meticulously clean the MSH rails inside the frame and the rails on the MSH itself. Inspect the hole in the MSH, the holes in the frame and the ends of the pin for any deformation.

    Try inserting the pin from the opposite side.

    Insert the blank end of a close fitting drill bit from the opposite side to hold the MSH in position and drive the drill bit out with the pin. Grind a bevel on the blank end of the drill bit if it won't start.

    Try assembling without the hammer strut pushing against the cap on the top of the MSH.

    Good you could finally get it reassembled. Sometimes tolerance stack up, burrs or etc can cause problems.

    That's how I always do it -- using a 1/8" punch from the back side to align the holes in the mainspring housing with the holes in the frame.
