Running your slide?
Last week I took a great firearms class. It was a CCW course/beginners course. The NRA certified instructor taught me a lot and I am a far better shooter then I was before, and a lot more knowledgeable.
One thing you told us to always do was to "run your gun". This is where you put your hand on the back of the slide and "punch" with your other hand. You do this when ejecting a round, putting a round in the chamber ect.
This is the first time I have ever heard this, and I wish I asked why but at the time I never though about it. He said we should always do this and this is how he and always does it.
Do you guys do this? If so why or why not? Is there any positive effect on your gun other? Or negative effect for not doing this?
