That's sound advice in any self defense firearm. It's what I teach under 99% of circumstances. Some exceptions are notably, my wife who was a great shot with her 45 Commander until six years ago when she got a very aggressive form of breast cancer which she thankfully survived but left her severely weakened for probably the rest of her life and so she can in no way tolerate the recoil of a serious handgun. So I got her a Kel-Tec PMR 30 in .22WMR with three 30 rd magazines. She prefers not to use it and I understand. Anywhere she might need one, I'm there and carrying. She knows how to chamber, load and fire everything in my possession, so if there is an emergency, she will acquit herself well, I know. She is after all, besides being my wonderful bride of 27 years, the daughter of a US Marine Colonel and a hero of WWII (R.I.P).
I have an elderly and very wealthy client whom I taught to shoot for his CCW permit. I've been working with him for months. He doesn't want to wear a holster and lug around a weight. He's got some serious health issues. To top it off he has the most extreme case of recoil sensitivity I have ever seen and he had it before he came to me. I start everybody and I mean EVERYBODY on a .22 revolver. (I don't care if you're a SEAL) -- if you take my CCW class you'll do a cylinder of 22LR from a S.A. Ruger before we go any further. This guy is dedicated to his own security. He could easily afford a top tier security team if he wanted it, but he want's to be prepared on his own. So we work together when he's in town (he jets around the world tending to his business interests).
At this point he has rented just about every possibility we can find at the local ranges and not liked any of them. I'm torn between the possibility of one of these on the small caliber side and maybe one of these in a 9mm. Problem is the latter is so new I can't find one anywhere, let alone one to rent! Brand new gun there's no track record on self defense yet. I've not seen many reviews, either. So I'm leaning in the direction of the .22WMR, but we'll see.
I did not mention that one of my carry tools is a Taurus 941 WMR with two inch barrel. I bought it, tested it, then did a hammer spring job on it and it is so nice now that I have placed a small Lazerlyte laser on the side. Very accurate at inside forty feet and never jams or fails to fire all eight rounds with the pull of the trigger. Nearly no recoil. Only thing I would differently with that tool is put a green laser on it instead of the red, but that’s just due to my aging eyes.
