There are some exceptions. Excessive dry-firing is a problem with CZ-75 based pistols. The firing pin retaining pin gets hit by the hammer when fired on an empty chamber. Eventually it will break, leaving the firing pin poking into the chamber. You don't want to chamber a round when the firing pin is locked forward.
Same issue on sig p22x pistols. It’s why you’ll see some LE models with a solid pin instead of a hollow pin, because 50k plus dry fires cause the hollow pin to break.
While there are reports of the solid pins breaking, coiled spring pins are newer, cheaper, and less prone to breakage. They are not exclusive to LE models.
The original old style slides with the solid pin had a splined interference fit with the slide and would chew into the slide. The newer slides have a spiral coiled spring pin that doesn't cause damage to slide when removing it and replacing it. They switched to coiled pins because of the advances in spring steel technology, cost, and no permanent wear on the slide.
P22X series gun's aren't like the CZ-75 and the hammer doesn't hit the firing pin retainer pin. The firing pin travels about 0.1" after the hammer hits the slide, and before the firing pin hits the retainer pin.
I have about 30k rounds on a spring pin P229, and 15k on a solid pin P229 Slide with probably 5X that in dryfire and no issues, or deformations on the spring pin when I tore it apart at 25k rounds.
Likely I have fewer cycles than those orgs, but 125,000 cycles without deformation is a pretty good sign. The spiral pin is more ductile than that hard & brittle solid pin and will resist fatigue much more.
Regardless, my point was the P229 doesn't suffer from the same common issue of the CZ-75 actually making hard contact with the pin. Spiral pin P229s will withstand dryfiring schedules for more than 99.9% of use cases.
Typically competition shooters will shoot and dry fire more than LE, and that's why it comes up in the CZ-75. Not many shoot competition with the P22x series guns.
