I doubt there was anyone worse than me when I first shot my LCP. I guess that was around 10 years ago when they first came out. Man, it hurt my hand and my finger. I almost missed the target. The round went extremely high and right to the very edge of the target.
THAT GUN ON THAT DAY GOT THE BEST OF ME
Thus began a 10 yr journey to get to be the best I could at shooting them. I trained at least once a week and thousands of rounds through them. Burnt 4 of them out.
1) eventually became use to the recoil. No longer hurt, Groups started coming together, I became faster and faster with point and shoot skills, faster at drawing and doing double taps to multiple targets etc.
Eventually this became like a hobby. Yes, I still love to shoot my other larger firearms, but I would say I am a "Niche" shooter in the fact that I love the small barrel guns. They represent a challenge.
Take on the challenge and it is my belief that you will become a better shooter with all firearms. Bigger weapons will become so much easier to shoot.
My old running coach was fond of saying /B] Advice that has stayed with me for years.
Possible solutions for the OP. Yes as the other poster mentioned. Cut down on the amount of rounds in one session and add more sessions. Sometimes I go to the range in the am and again in the PM for example. Quality vs Quantity.
In the running world, we called too many miles, "Junk Miles". No need for Junk Rounds".
Find a small barrel trainer in 22.cal and train point and shoot skills. I use a Phoenix HPA and it has been a tremendous help. I also train with BB and Pellet pistols
For my LCR, I bought a 22.cal LCR. Plus it saves on the cost of 380 ammo. And 22.cal can be a whole lot of fun to boot.
