The original posting asked in part, “I've always thought that dry firing is a no no. I wanted to get your thoughts on this.”. So, bear with me please while I sort of verge off to one side.
As a premise, personally I believe that dry fire practice, or its equivalent, is extremely important. As with any sport, you need to keep your skills honed as best you can.
Kathy Jackson, managing editor for Concealed Carry magazine, has a very good website (she and it have been mentioned in other topics in these MGO Forums), in which she has an article on dry fire. Take a look at:
http://www.corneredcat.com/Practice/dryfire.aspx
In that article she writes, in part, “Ten to fifteen minutes is all I can safely handle; after that my mind starts to wander. As soon as your mind wanders, stop immediately. That's a sign that you are not paying attention to what you are doing...”
I tend to agree with her. I must have a very short attention span because I get bored in very short order.
What I have done is to set up some targeting in my shop and have a pair of CO2 air pistols that I use. Granted, this is not practicing with your usual firearm. On the other hand, however, you do get practice of basic principles with immediate feedback that tends to enhance interest and overcome boredom.
Years ago I had some primer-fired plastic wad-cutters that I could shoot in a revolver at a backed-up target in the living room. That probably was even better.
