My wife (a 62yo new shooter) just got back from a week-long trip to visit her daughter and grand daughter. While she was away, I installed smooth-faced triggers on her G26 (at her request) and on my G27. I also managed to load a few hundred rounds and we're unloading them today at our gun club. She'll also be taking her Ruger Mark III Target and her Marlin .22LR rifle. She picked out the two .22LRs all by herself and she did the same for her 11-87 she shoots skeet and trap with. But before she spent any money, she shot several of my guns. And at one point in the process she told me to back off she'd buy what she wanted. I took that hint and watched her "shop" for several weeks at several local stores and on the internet. She also talked to our gun club manager and took several shooting lessons. And lessons was her idea, not mine.
She's a typical new shooter. They may not get that first pistol purchase (or any gun for that matter) exactly right, but who cares? If it's that bad dang, just buy another, and another, and another ... ad infinitum. She likes her G26 but plans to shoot her first IDPA match with MY Gen4 19. It just didn't take her long to start making really good decisions and the thing is they're all HER decisions, not mine. I'm just watching and grinnin'
Moral of the story when dealing with new shooters, from my perspective, is the same as with a marriage, "hang on loosely" ... advise when asked but don't push, don't lord experience over a new shooter and if they insist allow them to make purchasing errors. It's their money, the purchasing errors are not fatal (sell, trade, safe queen?) and sometimes you have to stumble to learn. In fact, you often get the best lessons from mistakes.
