Thumbs the safeties on the Romy Toks, while stupid and ugly, DO NOT affect reliability.
Just do what I do and leave the damn safety off. Carry the gun how it was designed to be carried, with a loaded round and the hammer at half cock. What you do is load a magazine, insert it into the pistol, rack the slide then CAREFULLY pull the trigger while gently riding the hammer forward then set the hammer to the half cock notch.
The Romy Toks (TTC) are spectacular shootin irons. Make sure to get the cool leather holster, lanyard, and some spare magazines.
PS: Just found out these cheap Tokarevs are all dried up online. You missed your chance pal. The early bird gets the worm. You might be able to find one on Gunbroker but you'll pay more for it.
