Dry firing safely as discussed above. Perhaps more threads out there.
Thanks for all your input.

¿¿¿What's best, in terms of not damaging any gun components?
1. O ring alone
2. O ring plus snap caps.
3. Snap caps alone.
4.  Laser training cartridge alone.
5. O ring plus laser training  cartridge.

¿¿¿Is it the same #83 O-ring for the Rami, p01 and sp01?

O-ring or a piece of soft rubber under hammer

Thank for sharing the links CZs_V8Volvos  :)

My vote:
1 then 3 or 4.

However I've done thousand dry fire 'bum" without o-rings nor snap-caps and no wear on any parts. [P-01 with CGW roll pin]

Cut a quarter inch thick piece of rubber eraser the width of the hammer, and put it in front of the firing pin.
Did you go into the forum search and look for dry firing of dry fire ?

UMMMM ^^^^^^^ not really a good idea.
Generate a lot of undue wear and stress.

Blaze orange foam earplug cut so it fits in the hammer channel but doesn't impede sights.

Or get a shadow/TS variant that doesn't have a firing pin block and dry fire away.  I actually use a set of dummy cartridges I built with no powder/primer that I filled the primer pocket with goop.  This let's me simulate the weight of a full magazine during dry fire.  I have them marked with red sharpie inside the case head groove for proper identification.

Cheers,
Toby

Yes I know... I was surprised not seeing any damages...
Anyway, once I've read other threads about it I've started using O-ring.

Thanks jurek.

My family enjoys using the Laser light cartridge together with the LaserLyte Trainer Target Steel Tyme with Plinking Steel Sound on our Glock 17 and 19. Reracking after each shot makes the rather enjoyable family activity tedious especially for my wife.  I'm thinking that a DA/SA pistol like the hammer striked CZ's (or the Taurus G2C/G2S/TH9 with double strike capability) will be perfect but I don't want to "hurt" my CZ's (and prefer not to buy another gun like those Tauruses)

CZs_V8Volvos,
Do not even think you hurt your CZ...
DA handgun is a perfect tool to be used with laser cartridge. I dropped SIRT pistol in favor of DA pistol. You can use it thousands times without hurting your pistol. Keep in mind, after 2 months the laser will end up with a hole in the back and you will need new one  :D (I'm already with my 3rd one).
After reading few threads about using o-ring, I've decided to start practicing with it. I'm using Danco #83, which perfectly sits on the back of slide. You can rack the slide and use the laser cartridge the same time (o-ring doesn't obstruct laser impact).
You won't find better tool for dry firing than your pistol with laser cardridge.

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.

I use o-ring and snap caps.  Just don't forget to remove the o-ring the next time you head to the range, click instead of bang is always disconcerting  ::).  Later.

The two loudest sounds are a "click" when you expect a "bang" and a "bang" when you expect a "click"

red silicone rubber o-rings are easier to spot than black o-rings

However you do it, be sure to check it occasionally.  Here's one of mine after 1000 or so rounds with a laser trainer

Wow... Well beaten up. Is it factory one?

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.  :o 8)

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.

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....

I just shove an old foam ear plug in the hammer.
