Is its really bad for guns to dry fire them?

I've been coming across manuals of older guns here and there recently (PUMA, PGP, F1 Ill..., etc) and they all mention that it's harmful to the gun to dry fire them? Why is this? Is it also bad for me to be dry firing my '12 Grey Ghost (which I can do given heavy valve spring)? Thx for the help

EDIT: I guess in the case of the F1 this had to do with the cocking handle hitting the end of the receiver thus deforming it. That seems like a gun specific issue then. So this rule only applies to certain guns?

First, there's a difference between dry firing and firing air without paint.

Poppet valved guns usually rely on the spring force of the air behind the valve to stop hammers from bottoming out with full force. When you fire without air, you get metal on metal smacking, which over time causes wear.

Right, I meant dry firing w/o air. So, this problem is limited (generally) to poppet valve/blow back (or double bore stacked guns like the PGP where the hammer will smack the valve when there isn't any air pushing the valve stem closed)? Is this a problem for nelson guns too?

i'd imagine those thin power tubes risk breaking with every move of the hammer...

the correct answer is who cares? just buy spare parts!

I only know of the BE Rapter that you could not dry fire without crushing the valve face

If I had to settle with a catch-all answer I'd say, dry firing isn't that big a deal, just don't do it more than you have to.

I've had Sheridans break after letting a newbie dry fire for 15 minutes.

I think the breaking power tubes in nelson guns is due to CO2 freezing and causing them the shatter.

On newer markers, you can burn out the solenoid by continuously dry firing them. Also, it's possible to blow out detents on the marker when firing them with air.

Had an Orange bolt in an Intimidator break while firing just air. Though since it's an Orange product it might just have broke by staring at it.
