Should I go with the Romanian TTC or Yugoslavian M57.
I have multiple Russians, Poles, Yugos and 1 Romy.
All of them shoot well and are reliable. They are flat, light and concealable.
The Yugos fit my (glove size Large) hand better when I wear warmth-gloves but I like the positioning of the Romy add-on safety a little better since I can more easily & quickly manipulate it just prior to pressing the trigger.
If you like to have a lot of magazines for your pistols, that should be a consideration in your decision since standard mags are relatively inexpensive while M57 mags are pricey.
Whichever you purchase, I would suggest taking the time to COMPLETELY disassemble (yes, including the "trigger pack") it so that you can thoroughly clean it, inspect it and stone/polish the "trigger" surfaces as required.
On one of my M57s with a
horrible trigger pull, I found that half of the problem was the result of someone having reversed an old, worn-out sear leaf spring rather than replacing it. Once I replaced the spring and polished the bearing surfaces, the trigger became pleasantly crisp and relatively light.
Enjoy!
