Thanks. I went ahead and edited it. I've done the same thing with the new system.It looks like he appended this to the OPs quoted post, instead of typing text outside of the quote brackets:
"mind sharing the part numbers of the cutters you used. Particularly interested in the carbide you used for the rail slide groove. Excellent work BTW"

If Americans really value their Second Amendment, they should start cutting steel. We're coming to that point...Very very impressive and a job (IMHO) well done, you must be the guy Biden is afraid of, a civilian gun maker.
Well now that this is opened up. How hard would it be for you to make stainless steel frame for your glock slide? I wonder how that would work and look?If Americans really value their Second Amendment, they should start cutting steel. We're coming to that point...
Pretty difficult.. One way I approach it is, what was the original manufacturing design intent? Was it intended to be machined, or molded, or stamped? Looking at a glock frame it was intended to be molded, so with that said it would be very difficult to mimic the design without using some form of MIMS, molding, casting, multi-axis CNC etc... Traditional manual machining methods would be difficult, next to impossible really, to mimic the design. Could it be redesigned to accommodate the manufacturing methods used on manual machine? Sure, why not? But you may resemble more of a 1911 frame by the time you're done. That's why a 1911 looks the way it does. When Mr. Browning designed it, the design intent was to be manufactured on manual machines, obviously because of that being the only form of machining for that time period.Well now that this is opened up.

Great reply thank you for all that good information. So in some cases metal frames would actually take a pounding. Plus Glock was designed from the beginning to use the polymer frames. Where as CZ, and JMB 1911's are designed from metal frames except my CZ P10F of course.Pretty difficult.. One way I approach it is, what was the original manufacturing design intent?

In short, it depends on how creative you are and how deep your pocket book is.
But, to answer what a stainless steel glock frame would look like. Here you go. keep in mind this is NOT my design nor will I take credit for it. It was a company called CCF race frames a few years back. They offered them in stainless, aluminum and titanium. I believe they did it with a MIMS system of some kind. This is one put together a couple years ago.
P.S. Another note on design intent. They recommend using factory plastic guide rods in the CCF frames because the steel doesn't move/absorb energy as the plastic frames do. Like dry firing a bow, the energy has to be displaced somewhere. In this case, steel frame and steel guide rod. One has to give eventually.... Most likely catastrophic permanent deformation...
Yup. Pretty cool. I'm in plastic injection molding so I have a little understanding about the restrictions in injection molding and how complex a mold gets in order to make something and then be able to get it out of the press.

Again thank you for the time you took to educate me.
As a master machinist, (this is in reference to a frame) possibly, you would definitely need a tombstone mounted on a 4th axis, or your gonna have a crap load of time in building fixtures and set up.Do you all think this would be possible on a 3 axis CNC?
I am working on building a V1 Engineering mostly printed CNC machine. It is what you think, a mostly 3d printed CNC machine with EMT conduit and 3d printer stepper motors for motion control. It probably won't be able to hold .0002 tolerances but it's also a home grade steel-capable CNC machine for under $1000.

A slide or similar item that can be held in a vise or simple fixture, your probably gonna have better success with.
The V1 machine is good for the hobbyists, but lack rigidity, there for slower speeds & feeds equalling small cuts, lots of time to do small operations.
What kinda control are you running?( if it's a G code machine I can help you program)
Pictures of your machine.
Might be better off not hijacking this thread but starting a new thread.

I wish you the best of luck. I program CNC VMC's , I use no cam software, I program off the top of my head. I will offer my help should you wish. I have a tool room in my garage if parts are needed.I apologize but I don't have the machine built yet. I have all the printed parts done and the conduit rails bought, but there's still a host of bearings and other hardware I need to buy and assemble to make it run. I'm also planning to start with a lighter duty CNC that would probably not be suitable for steel, more so I can learn about it as that spindle is much less expensive than the steel-capable one.
I am going to be doing some minor changes to V1's design to increase rigidity. Other builders of this CNC have noticed it lacks some rigidity so they've come up with some methods to make it better and once those are done it can hold .001" on a runout gauge. Pretty good for homemade if you ask me. It will use Marlin flavor of G code more than likely as that's what I know how to write/edit firmware for and that's what the repurposed board originally used. I'll probably pick up Estlcam or try FreeCAD to write tooling paths at first and my plan is to use a feed and speed calculator to get a rough idea on that. I also plan to machine florist foam first for each operation as I'm told if you make a mistake that stuff doesn't destroy bits like mistakes in steel do. The CNC spindle will be powered by a separate power supply with a potentiometer for speed control. There is no digital RPM readout on it so I got an optical tachometer I'll use to set RPM before beginning my cuts.
Also, I am only planning to use this CNC to machine the slide and other small parts as needed. If I can cut my cost on a nice slide from $500 down to less than $100 once I have the bits and such it would be well worth the investment for me. Bar stock and Cerakote is cheap. Machining on a CNC and using associated tooling is not. I would build more Glocks as there are so many different projects and uses you can do if you have access to 3d printers and CAD files etc.... but the slides are just so darn expensive. Even the cheap eBay ones are well over $150. I saw on one of the posts here the bit to cut the dovetail for the rear sight was $200. Mine will likely go without in that case and just do a red dot optic cut. I will also probably opt to modify the firing pin hole to take a round pin and CNC one as I do not have access to anything that can do EDM, unless there is a homemade option I don't know about.
The frame itself can be 3d printed on the printer(s) I already have. I currently have a custom designed 45 caliber Glock frame that I use as well as a 9mm Glock 19 frame that are 3d printed. They work well and have no issues. Most of the frames that are released nowadays for 3d printing require the designers to have live fire on them before release. The group AWCY? (Are We Cool Yet?) REQUIRES a documented 1000 rounds of live fire on frames and it survive during beta testing before allowing a public release. I have files for Glock 19, 17, and 21 sizes as well as compacts, but I'm not into those really.
This is not a rush project and I intend to take my time with it and use spare money and time as it comes and goes. To put it simply, this is more of a "can I do this? I'd like to try." kind of project than anything else.

You need to run either mist coolant or flood coolant. Chip removal & tool life will be greatly affected.
Are you part of a machinist club? We have one here in Ft.Wayne. do you read homeshop Machinist? Machinist workshop? Digital machinist?
What materials are you thinking for your slide?
