Sea Sniper enclosed track safety problem

I recently bought a Sea Sniper enclosed track rear handle gun, one of the last few made with the sliding safety mechanism. The safety works fine when the gun is not loaded but as soon as the rubbers are on the sliding safety is completely stuck.

Any ideas what would cause this? The trigger doesn't seem to move once loaded and I can't see any other force acting onto the sliding mechanism that would cause it to jam.

I am not familiar with the Sea Sniper safety, but for it to jam the trigger must be leaning on it when load is applied to the spear via the bands and the mechanism then moves slightly to take up the strain. On forward trigger mechanisms the sear lever under load pulls the trigger forwards and slightly away from any transverse safety sliding bar directly behind the trigger. With reverse trigger mechanisms the load from the sear lever also pushes the trigger forwards as it presses down on the top of the trigger above the trigger pivot pin and for the trigger to go back the other way the sear lever would have to tip the top of the trigger forwards which should not happen as that is what the gun does to shoot! Some photos would help, or a bit more info on the type of Sea Sniper gun as they made lots of different guns. Remember that safety devices must be "off" for the shaft relatch as otherwise the triggers push back on the safety bar or cam and prevent the relatch of the trigger mechanism.

Since I wrote the above reply I have seen a photo of that Sea Sniper sliding safety which is mounted directly behind the sear box and has a turned up rear end with a vee shaped notch cut into it to double as a rear sight. The trigger mechanism is a reverse type with the trigger pivot at the front end and the sear lever pivot pin at the rear end, hence the safety slide must act on the sear lever by catching a step in the backing projection which sits behind the sear tooth that engages the spear tail notch. When the trigger is pulled the sear lever tip rolls down and any part of it rearwards of the sear lever pivot pin is pushed upwards and that will be where the safety slide is blocking it when pushed forwards and set to “on”. For the safety to be jammed with the gun cocked to shoot the band load is rolling the sear lever slightly forwards and nipping the front tip of the safety slide. To fix it a small amount has to filed off the sear lever at the rear to increase the clearance or the trigger adjusted to tip the front end of the sear lever up and hence the safety engaging step down at the back end of the sear lever. Some reverse trigger mechanisms have a screw that adjusts the trigger by changing the adjustment where the trigger leans on the front of the sear box frame as these are frame lock mechanisms, not cam locks. For example a C4 trigger mechanism is a frame lock mechanism. A Biller trigger mechanism is a cam lock.
