Here's some lessons I have learned on shaping CZ 75 frames. Specifically undercutting the trigger guard and beavertail. The pistols I am showing still need to be refinished, so you will see some rough marks that will be removed when sandblasting in prep for hard chrome. I just put them back together to shoot them and see how I liked the modifications before doing the final and more permanent step of refinishing.
Pistol #1: I started this journey with an old CZ 75 pre-b from 1987. I had to do some other frame mods for it to accept newer magazines but that isn?t what I?m covering.
I worked on the beavertail and undercut the trigger guard. I should have removed less material from under the beavertail and instead removed material from the top. See the pics to understand how it looks a little funny. BUT it feels incredible!
I didn?t bevel the edges up under the trigger guard enough. You?ll see that progress in other pistols, and I?ll return to this one and bevel those since this hasn?t been refinished yet. Outside of the beveled edges this feels incredible!
Pistol #2: After feeling the results of the frame modification on my old pre-b I determined I had to do them to my classic 75 Compact. Due to some other members (Underwhere and others) I realized I should remove material from the top of the beavertail to aesthetically look closer to an upswept beavertail. I didn?t get it all the way to upswept appearance, but it looks better than my first. Feels fantastic too!
I beveled/rounded the edges under the trigger guard a little. They aren?t sharp to be uncomfortable, but it definitely wasn?t as much as I needed or wanted. I took the undercut up far enough though. Once I bevel/round those edges it will look like I took it further. This makes it point about the same as my SP-01. Whereas, before it pointed a little low for me after practicing with my SP-01. That was in part due to the thicker beavertail changing the angle when I gripped the pistol.
Pistol #3: After the success I had with my classic 75 Compact in how the grip improved I wanted to do this to my SP-01 Compact 99021. The trigger guard undercut had especially made a difference in how comfortable my first two pistols are for my hands and grip. Plus I had this idea that I would turn one of my 99021?s into a Shadow 2 Compact. I?ll include pictures of my other 99021 and normal SP-01 for comparison.
I did the trigger guard undercut about as far as my classic 75 Compact, but I really beveled the edges on this one. It makes it feel even better! You can see that rounding those edges makes it look like I took it all the way to the magazine release. Again, I took it about as far as the picture for the classic 75 Compact, it just looks this way from the beveling. This is more aggressive than my normal SP-01 and makes me want to do this to my SP-01 too. It is freaking fantastic!
The beavertail was already upswept. My goal was to remove material to get it close to my SP-01. It feels great and looks pretty close.
This turned out so well that I want to do it to my other 99021! Now I just need to do some touch ups and get these off to be refinished at some point. I was really wanting Hard Chrome!
This takes a lot more time than polymer pistols. There are tutorials on the ?how to?, I just wanted to get some lessons on shaping shared with the group.

PS- CGW or CZ Custom, pretty please make some programs on your CNC machines to do this. You?d make a killing once people feel them in their hands. Plus I don?t know if I want to do this too many more times by hand...
