It has the newer style front sight.
It has the ring hammer.
It has the newer style squared off trigger guard.
But, it still has the older style safety and slide release levers.
Like they said, a transition model. Not a "B", not an older/original Pre B due to the three things mentioned above.
But, a very nice pistol. Easy to upgrade the sights on if you wanted to, someday.
You should be able to easily replace that big lanyard loop pin with a standard hammer spring cup pin. Can't say for sure without seeing the frame but the pins don't cost too much and easy to replace.
Be careful if you remove the safety. Small parts inside (there's a procedure for getting it out and not losing the spring/detent but I don't know it/use as my only Pre B is a CZ85) can be lost and you can't order an original replacement. I've read you can buy/use a similar piece from a P07 or P09 safety, which you can order from CZ USA. Same for the slide release. No longer available in that exact form/look. The B models use a different looking piece.
Like everyone is saying, beautiful pistol. Enjoy it.
