Inadvertently fired with the hammer 'safety' pin extended. The firing pin, detents and spring popped out and of course the spring and detents lost. Tried replacing with ball bearings and another spring, They keep popping out so I just pinned the caliber selector in with a brass rod.
How do I get parts to replace lost ones, or fix the problem another way so I can switch between rimfire and centerfire barrels without cutting and bending in another brass pin every time.
Thanks.
