No dry fire issue with any component in used PO1?

[Laufer]

Being well-aware that modern guns, other than rimfires, are resistant to metal stress during dryfiring, there is one specific reason for the question.

People online discussed a CZ component needing replacement in whatever CZ model, with evidence that d.f. caused it.
They sometimes said nothing about which series they were talking about.

In case I wasn't clear---has Any component needed replacement due to very constant dry-firing, in a PO1?

Guessing the firing pin. Not an issue if snapcaps or an o-ring were in place. Ymmv

They are talking about the firing pin retaining pin. When dry firing the without a snap cap or o-ring the firing pin will hit the retaining pin and can damage it over time. Cajun Gun Works makes an upgraded pin that will be better for dry firing but I would still use snap caps or an o-ring.

As well as the previously mentioned firing pin retaining pin you might want to get a CGW trigger return spring.  Folks here say drying firing (double action dry firing at a rapid/sustained pace) can speed up/cause failure of the trigger return spring.

Thanks.

All of that said, as part of the NATO approval process, the P-01 is supposed to withstand 4000 dry firings.  Here's the CZ press release on it from Feb. 2003.

Yeah, but watch out for 4001 ;-)

Seriously, the FP retaining pin and TRS are two parts that get swapped with CGW parts on any CZ I buy. I also keep a spare slide stop on hand, as the design puts a lot of stress on that part and it can break unexpectedly.

Are those parts in our PO1 guns a little more Brittle than in the standard CZ 75?

Best solution: simply buy snap caps for Both this used PO1 and the used Sig P229 in .40. Roger that?

I would say no more so.

That is the approach many take to address wear when dry-firing.

However, it might be wise to have spares of these parts on hand anyway if this is a gun you intend to shoot a lot. It really depends on a couple of factors: 1) are you keeping the gun stock, and 2) how tolerant of "down time" are you if you have a part fail?

If you keep the gun stock and have a failure, you could possibly get replacements under warranty but that would take time to work out. I keep spares on hand because I use CGW upgrade parts to begin with and - even though I have a spare P-07 - I don't want to be waiting a week to get a replacement part sent.

All of this hinges on how much and how often you shoot the gun, though. Think of it like you would if you knew you were going to put a lot of miles on your car - you'd plan in advance for the parts and maintenance it would require to keep the car on the road. Same concept, really.

s0nspark:
Nice explanation.

Even though I'm really enjoying the .40 cal. Sig 229R (DA/SA) just as much, and bought it to have a top-quality alternative, it would still be a shame for any component to eventually break.
Being mostly a rifle guy (--Until the CZ and Sig--and facing the fact it's time to acquire some handgun skills), this will limit wear. Still gonna buy the snap caps.

Well, it is a fact: parts wear and sometimes break. Just a fact of life

As long as you stay on top of the recommended maintenance and watch your round counts so you can replace wear items proactively it isn't really a big deal.

They're actually the same parts.
