I wouldnt do it a lot. functiosn check or not.
Honestly i try to avoid it.
but it <is> part in basic tng to train yourself to shoot well.
Dime on the barrel.
Pull the trigger for dry fire making sure it doesnt budge or even fall.
but it snot something I would do on my own rifle.
On my Rugers Revolvers its a non issue.
I must have dry fired my GP100 thousands of times as part of my target aquistion tng in front of the TV
