Snap Caps with centerfire?

Is it accurate to say that dry fire on a centerfire won't hurt without snap caps? I get the mechanics of the firing pin however I have been making sure I don't pull the trigger without a snap cap. Another thing someone told me that I just trusted and never verified. At IDPA events I cringe when they ask to pull the trigger to verify it isn't loaded.

I just read this from PewPewtatctical:
"If your handgun/pistol shoots centerfire rounds (9mm, .40 S&W, .45 ACP, etc) instead of rimfire rounds (such as .22 LR), then you can dry fire all you want since the firing pin is not actually hitting anything. Rimfire firing pins hit the mouth of the chamber when there’s no cartridge so you should practice with snap caps that take the hit."

No harm dry firing any modern center fire hand gun. Just don't do it on a Star B.

I'm thinking that a lot of dry firing could cause some embrittlement on metal parts that are slammed onto one another.

This is not true of all rimfire firearms. Only a few will actually hit the breech face when dry-fired. Late model (2001+) Browning Buckmarks will peen the breech face if dry fired because they extended the FP slightly when they redesigned the assembly. Older ones do not. Nor do Rugers or S&Ws I have owned. No .22 rifles that I know of will hit the breech when dry-fired. I never use snapcaps or anything else and I have dry-fired some guns in the thousands of times with no problems. Most really good and pro shooters dry-fire even more than I do, since many have daily training routines they go thru many of which require dry-firing.

I dry fire my guns all the time. I have never had an issue. I like to do it to get the feel of the trigger. I also store them fired. It takes the pressure off the firing pin spring. Not that I think that really matters.

I’m just curious; as long as the firearm is pointed safely at the downrange berm, why “cringe?”

Because I was once told never to pull the trigger unless there was a snap cap in there and I'm OCD about everything.
