@rowdybI just downloaded this really interesting app, its actually a game, but in it you step by step completely disassemble and then reassemble a CZ75 in 64 easy steps (lol). It’s 3D so you can zoom in/out, spin, flip, rotate and change the viewing angle. If you try to reassemble a part before its time, it doesn’t allow you to do it, but it does have a “hint” function which highlights the next part in sequence so you don’t lose your mind. The only thing it doesn’t do, is finess the parts back in for you in real time, that’s all on you, but it is an awesome visual aid and I like the 3D feature, so many times fine details are lost in real time videos due to lighting, camera angles etc.

I haven’t tried applying it in real time yet, the pistol hasn’t had the rounds to warrant that yet and the field strip is an absolute no-brainer with the CZ, but when it’s time to do a detailed disassembly I am going to be relying on that app because the closest gunsmith is 120 miles away.
