22LR Schultz Larsen M77 trigger, bolt and firing pin adjustment par jcm8182

To complete my post of July 12, 2024, I offer you a second option to resolve the firing pin anomaly observed on
the S&L M77 nr 25700.
From 1924 to 1992, the .22LR Schultz & Larsen models were equipped with numerous trigger variants resulting
in adaptations of the bolt and firing pin, the firing pin hammer modified to take into account the positioning
offsets of the trigger in the receiver. These weapons are sometimes sold with a bolt, trigger and firing pin
assembly that is not adapted to the weapon or that is new or confused with another model.
It is possible to obtain a new original firing pin compatible for all models from the M24 to the M77 but to be
configured and dedicated specifically to the bolt, weapon and trigger assembly in your possession. This
modification will require lathe and perhaps gunsmithing expertise.
Here are 3 different firing pins: that of the S&L M77 nr 25700 firing pin which prevents backward movement,
that of the fully operational S&L M77 nr 19745 firing pin and a new original firing pin from Denmark ( From:
https://gb.bisgaardnielsen.dk/shop/141-schultz-amp-larsen-m70-riffel/9430-firing-pin-1type-f-m24-to-m77 )
or https://gb.bisgaardnielsen.dk/shop/141-schultz-amp-larsen-m70-riffel/10510-firing-pin/
but not yet reconfigured ).
The 19745 firing pin inserted in the bolt of the S&L M77 No. 25700 allows the weapon No. 25700 to be fully
operational. On the other hand, the 25700 firing pin inserted into the bolt of the S&L M77 nr 19745 again
prevents the rearward movement of the 19745 bolt in a weapon that worked perfectly with the other.
I therefore modify the new original firing pin to copy that of the bolt of the S&L M77 nr 19745.
(see jpeg for precise dimensions). Note that the new pin is made of hardened steel.
Also be careful that certain complete bolts are not interchangeable from one weapon model to another. Make
sure the bolt is tight, the bolt handle can be reversed ( lateral side up or down) to compensate a possible wear.
