I had a nice long post typed, then I managed to click the Google button instead of the post button. Grrrrrrr, I hate it when I do things like that.
My CZ is marked "AAL -- Phila., PA" on the front left of the slide, and the box is marked with "Action Arms Ltd." Paperwork inside the box says that Action Arms is the exclusive importer. The gun is a straight CZ 75. The friend I bought it from got it in the early 90s, I believe, serial number V233*
Let's see if I can do this right the second time around.
