I reconsidered the Minx as a practice gun for the LCP because it's a single action pistol, while the Taurus is a DAO, which is more like the LCP triggers are.
It's great to hear that they're a close match in ergonomics, I'll definitely buy one in the near future.
Good point on the fact that I would agree that having a 22.cal trainer in double action would be the best. One reason why I also bought the LCR22 to go along with my LCR9.
As far as the other poster that said recoil would have to be the same, I most definitely disagree. With or without the Recoil, you have to be able to come to target quickly with such a short barrel Pistol or revolver. Recoil should not matter as you are going off target anyway. The Point training will teach you to get back on target quickly and naturally. You do not point and shoot like a target gun. You are constantly moving the gun into different positions anyway.
As Far as the OP and in Physical infliction of shoulder pain. Let me say this. After being a competitive runner since high school and later a coach, I became a total believer in stretching exercise's and doing them daily.
I noticed since he posted that I have a similar problem with my shoulders especially when reaching high. I noticed this a few days ago when I was training with the heavier weapon, my 20ga. Pistol grip shotgun.
STRETCH THE ADJOINING MUSCLES.
The muscles from the should like all muscles will be affected by other muscles. Proper stretching can help give
more movement to the should muscle. Strecth and these muscles will not pull on the shoulder muscle or tendon/Bursa
Muscles are like SILLY PUTTY If they are not warm, or stretched they become tight and like silly putty will tear or break off with ease. However once the silly putty is warmed you can stretch it better and give a much larger range of movement to the shoulder.
Learn the Proper way to stretch. Breath deeply on the stretch. Stretch the muscles gently at first. Not full range. Just a little, let up and stretch again.
You will be surprised at how much the added range of motion you will have.
I also use small dumbbells build up added support to the long range sessions.
