Thanks for the insights on that, 44. Well, I have thought of some upgrades and changes, but I would want to keep them mostly internal. I really think the design of this gun is strikingly beautiful and would want to keep that, but I do want something with modern production techniques.
You say you design and build guns from scratch, and I looked at your website. Very impressive stuff. Despite your comments above, I think my first step is to reproduce the frame and slide of the CZ-52, making it parts-compatible, and then go from there in making changes.
My favorite thing about the design is the roller-locking. One consequence of the roller locking is that the barrel doesn't tilt. That has some good implications for accuracy potential and it also means that the recoil spring is around the barrel, so there is no guide rod. This means that there is plenty of empty space under the barrel inside the frame. One thing the CZ-52 lacks is a laser sighting system, but there is plenty of room in there for a fully internal laser, like a Lasermax system. So that's one of the mods I'm looking into. Wouldn't change the appearance but would add a whole new capability. It would also be unique; no other gun can put a laser there because all other guns have guide rods.
I have a Lasermax for my Glock and it doesn't work well to put the laser in the guide rod.
Anyway, another question for you: since you work in this area, would you do some work like this on a contract? I think the first step would be to blueprint and produce a replacement slide.
Thanks
