Okay, I fired the 9mm Hungarian Tokagypt and kept the brass. It does have a very light primer wipe, but nowhere near as severe as on yours.
I was using Sellier & Bellot commercial 9x19, but I noticed that this uses silver-coloured primers and not brass like on your S&B commercial 7,62x25; perhaps the rounds you have use a
very soft primer.
Next step I will put calipers to the firing pin dimensions and protrusion, to see if the older pistols show a difference.
there was no cosmoline in the action at all when i took it apart. it was spotless.
You did take out the firing pin, and found no Cosmo on the spring or in the channel?
so, any help on where i can get a pin and spring, just in case?
Wolff operates at Gunsprings dot com, and they ship to Canada. Put something for every gun you have in your cart.
New firing pins are made by Gun Parts Warehouse [dotcom], but they don't ship. You'd be looking at spares stripped from existing pistols if you need a replacement.
I have heard that under heavy use, TTs do tend to fail at the firing pin.
