Post 19; yes & no...
I agree with part of post 19 but also disagree with a section of it.
Yes, a new or entry level gun owner could benefit greatly from formal class room instruction but I would not rely on or expect a local gun shop clerk or sales mgr to give a honest, open unbiased opinion of what class to take.
Many gun shops or chains have "instructors" or cadre available to teach new gun owners the basics but some are honestly better than others.
The NRA or a local gun/rifle club may have better resources.
Web forums can help but I won't put a lot of stock or spend a ton of $$$ based solely on a internet message or topic.
Every 2nd matters.
