I was shooting my new M70A pistol and suddenly the slide fell off the frame.
The clip that holds the slide lock pin in place had popped off; the pin fell out and released the slide.
I reinstalled the parts and noted that the clip installs by finger pressure, unlike the TT-33 which is much tighter. On recoil the clip pops forward, releasing the pin.
So I reversed the direction of the clip, so that recoil pushes it on; not off.
I finished a fair amount of shooting and it stayed put.
If the TT-33 tends to pop the clip, this might be the fix. My TTs have never had a problem.
