IF YOU ONLY HIT THE SAFETY AND THE GUN WENT OFF,YOU HAVE MORE THAN JUST BENT POTENTIAL BARREL OR CRACKED STOCK ISSUE …
SAFETY is first line of protection ,the trigger itself is two stage and should not go off with out pulling at least to it.
Did you hit it ?
All points mentioned. Are VALID.. SEALS WILL BE FINE. . bent for sure if it was full cocked release. That’s fixable. If your lucky the wrist area did not crack
Remove the stock and inspect all screw holes and trigger area for fine cracks. use a magnifying glass. The 350 only uses two areas if I recall,
front forend and rear guard. Front screw is into the wood only.
Lay the action on a flat surface on the breech ,shim the rear so the compression tube is level to flat surface.. Then look down the space from breech to muzzel. Most Diana’s had droop from factory. So maybe it’s strainer now. Then do the same both sides and you will know if adjustments are needed. Barrel bending is common and doable.
