No. Maybe because I was trained as an engineer and thus things that are mechanical come as second nature to me?
Many guns are different and thus "one size fits all" training won't work.
I learned by reading the manuals that came with the guns (long before the Internet info became available). Today, that plus the various info you can find online make paying someone for training unnecessary in my eyes.
I did watch the president of L&R clean guns in ultrasonic tanks (that none of us could afford . . . he was using the commercial ones that will hold a rifle and probably 10 gal of cleaner), but I couldn't really take away any real knowledge from watching that happen.
At the end of a Second Amendment Sisters session I had a lady ask me to show her how to clean her S&W CS9. I had never touched one of these models, but it was easy for me to clean it and show her what I did. Problem was that she had paid someone to do the same thing for her previously (and she offered me money, I refused and told her to learn how and teach others . . . that was the best payment she could make).
Many people do NOT learn by watching others, but need to do it themselves. I took that approach in teaching (one-on-one) some clients about computer skills years ago (I printed out a script for them to follow, then let them do it under my watchful eye). That's the ideal way to teach, in my mind, but won't work when someone springs an on-the-spot request on you as was done to me above.
Belonging to private clubs ever since I got into shooting, if I had/have a question and someone else (experienced) is around, I go to them for help. Likewise I pass it along if a newbie has questions. I never accept money for doing this, just tell them to learn and pass it along to others. Keeping the knowledge flowing is the best payback.
That's my 25-cents worth (2-cents won't buy you a breath of air anymore
).
