I have so much to report on I'm embarrassed to say I almost don't know where to start. But I am spending today and tomorrow if necessary, as long as I can stand and lean taking a complete set of pictures comparing the models that I have against a CZ 75 Pre-B as the base model. I made a 1" grid on a white backing board. and I'm going through every model one at a time right next too the Pre-B, on top of, from the front, from the back and from the top down. That's a boat load of pictures, but I'm using tape to mark what pistol is which so no matter who sees them they will know which is which. I'm about to copy the first set of pics to my computer so I can look them over, and then print them out so I can use it/them as my model for every picture set to look in the same order. Fist one just FYI was the SP-01 next to my Pre-B, I think the next one is going to be the with 40P. Wish me luck.
