Again, it is not stated in the owners manual (I don't know why they are being so chintzy with the ink!), but according to their website's FAQ section:
http://www.smith-wesson.com/we...12§ionId=10504#2
"Can I dry fire my S&W handgun?
Q: Can I dry fire my Smith & Wesson?
A: Yes, except for the .22 caliber pistols..."
As an interesting side note, here is the section from one of my Ruger revolver manuals:
"DRY-FIRING: Going through the actions of cocking, aiming, and pulling the
trigger of an unloaded gun is known as "Dry Firing." It can be useful to learn the
"feel" of your revolver. Be certain the revolver is unloaded and that the gun is
pointing in a safe direction even when practicing by dry-firing. The Ruger New
Model revolvers can be dry-fired without damage to the firing pin or other
components."
And from the SR9 manual:
"Going through the actions of cocking, aiming and pulling the trigger on an
unloaded gun is known as "dry firing." It can be useful to learn the "feel" of your
pistol. Be certain that the pistol is fully unloaded (both the chamber and magazine
are empty) and that the pistol is pointing in a safe direction even when you are
practicing dry firing. The RUGER® SR9 pistols can be dry-fired without
damage to the striker or other components as long as the magazine is inserted.
CAUTION: Dry firing your RUGER® SR9 with the magazine removed may
result in damage or unnecessary wear to the striker blocking mechanism."
