Ok, since CZ in thier infinite wisdom only felt that a single page insert in the 75 manual was needed on the Phantom, how the heck do I remove the backstrap from the Phantom?
There's a pin holding it in place, but when I use the punch that's included it only moves a couple of mm, then sticks. Same result on either side and no, I have not used a pin punch with a driver to get it out as I do not know what the composition of the pin actually is and if doing so might damage the pin.
It looks like the other backstrap doesn't have as tall a profile as the one that's on it now, so I'd like to swap them to see which I prefer. A little techie help would be appreciated.

The lanyard loop is the mainspring plug. Neutralize the force by pushing the plug in a bit and then the pin will come out easily. I usually hold the grip and push the lanyard loop against a solid surface like a table.
pretty easy stuff.

Dorkfish,
(oops, looks like PGT Neon and I answered the question at nearly the same time)
Unload the gun, remove the mag. Push down on the gun from the slide with the lanyard (hammer spring housing) resting on a table top or something that won't get marred. You need to push the main spring housing up as there is spring tension against the pin. Push pin out, slide off the back strap. Installation is the reverse.
Can't remember where I saw the instructions for this.
I'm off in the morning to MS and won't be back for about a week. Good luck

Thanks much to both of you. I'll try to get it swapped out today with the new beta.

That did the trick.
If you're new to the Phantom and about to uptake the backstrap swap, please take a moment to read this.
1. Completely unload the firearm and visually check that it's unloaded. No magazine or ammo should be inserted at this point, if it is take it out!
2. Make sure the slide is fully forward.
3. Place the base of the frame, specifically the lanyard loop, on a hard surface. Make sure you cover the surface with something that will not mar the finish of the firearm or your wife's kitchen table/counter.
4. Apply continuous downward pressure to the top of the slide so that the lanyard loop retracts into the frame. If you go too far, don't worry it's going to stop on the backstrap pin.
5. Once the lanyard loop is fully depressed, take out the pin punch that should have come with your Phantom, lessen the downward pressure just enough that you can get the pin to shift to one side or the other. It can go either direction. You may need to wiggle the pressure downward and upward just a little as you drift the pin out.
6. Remove the pin fully. DO NOT release the downward pressure just yet! Parts will fly out and you'll become a cleche to the fullest.
7. Carefully remove the downward pressure, be sure to keep your hand at the ready.
8. The lanyard loop should fall right out. Caution, the mainspring is attached to the lanyard loop and it may fall out when you remove the lanyard loop.
9. Slide the old backstrap straight down along the spine of the frame.
10. Install the other backstrap in the reverse.
**When reinstalling the mainspring and lanyard loop, make sure you hold flip the pistol over and slightly angled toward the backstrap. This will put the hammer pin in the proper position for mainspring installation. If you do not put the pistol in this position, the hammer pin will slip into the magazine well and you will not be able to use the pistol...a function check will quickly tell you this, so follow my lead and you shouldn't have that problem. Then just insert the lanyard loop in the proper direction, apply downward pressure to it again and reinstall the pin.

Thanks guys that helped me and saved me a lot of time trying to figure it out.
