Dry Firing Best Approach

Yes.  Happily they're $2 on the CZ website (probably 1/3 of that in the hardware store) and really easy to change out, so it isn't a big deal.  I just pop mine out every once in a while and take a look

Think about CGW pin ($5). Mine is still in great shape after over 10K live rounds and about 20K of fry firing.... I was surprised seeing it during last reassembly.

Agreed.  After finding a hole gouged in my stock retaining pin and a chunk of it in my firing pin channel, I decided never to leave a stock retaining pin in any CZ I owned.  It isn't worth the risk if that's a gun you will rely on for defense.

The CGW pin takes a beating for thousands of dry and live fire rounds and it doesn't get deformed.  Mine just turned shiny, lost its dark finish, but the structure of it wasn't affected.  If you use o-rings for dry fire, it even takes a very long time to lose its finish.

O-ring and oil applied to trs before each session. DA dryfire puts a lot of heat into the trs and can cause early failure.

Some years back I had a Witness Sport Long Slide (.45) that I dry-fired a lot, trying to smooth out the DA mode -- several hundred trigger pulls a night for weeks. I also polished the trigger bar and the inside of the slide.  The only thing that ever broke was the bloomin' trigger bar, and I suspect that was just a fluke.   Similar spring and a similar design.

I'm pretty sure that the trigger return spring gets compressed the same amount when firing SA as DA.  The only difference is that in SA mode, the spring is partially cocked by slide movement.  The only part of the trigger spring's compression that is likely to cause spring wear is the final part of the pull, when you're getting that spring closer to it's design (elastic) limit.  And this is true whether you're dry-firing or live-firing. And with live fire, the heat form the round being fired will eventually work it's way into the trigger spring, too.

I think it's going to take a lot more heat than can be generated by dryfiring OR live firing a CZ to damage the trigger return spring.   I doubt the oil is going to do to have much effect, either.

You won't find better tool for dry firing than your pistol with laser cardridge.

COOLFIRE TRAINER with the optional laser beats any other type of dry-fire....it recoils similar to live fire with low power factor 9mm so you use your own gun and actually track your sights or red dot........expensive but pays for itself in saved range time and ammo costs in no time at all, plus it makes dry-fire alot more realistic and fun so you want to dry-fire more often

This looks more than dry fire   
With all these tricks added, it is not dry fire anymore. At least changes it's idea....
