I had a set of Crimson Trace grips for a while and while I found I could be very accurate with them, it was only when I took a long time to find the laser dot and I was very slow.
I had a Vortex Razor red dot for a while, but it was on a rifle and I went to a magnified optic instead.
So that's my experience with lasers and red dots.
I'm shooting handgun now at the range for fun and I want to cheat as much as possible. I'm shooting a heavy handgun with fairly light ammo. I just want to make everything as easy as possible. I'm not interested in changing the gun for a different type or model. I want to know about what accessories or modifications can make the fundamentals easier. It could be a better trigger, better grip, laser, red dot, scope, FO sights, porting or compensators...
I think some of the modifications out there are really just for chasing those last few hundredths of a second in competition and while they might "work" they don't really add anything for the user who isn't capable of operating at that level. I'm looking for things that make it easier for a novice.
Problem is, you can’t buy skill. Every one of these changes does not make you a better marksman.
I’d suggest buying 1000-2000 rounds of ammunition, get some instruction and work with what you have. Work on dry firing a lot, too.
Being a member at an outdoor range is better than an indoor, especially if you are allowed to shoot at mutiple targets, at different distances. If you’re a total novice, start shooting at 5 yards keeping it in the black. But push yourself with moving it further back. As you get more comfortable, if allowed, work using a shot timer. Score your targets against time, Progressively moving back.
Our club only allows 25 yard plates for handgun, so I had to get good fast or the steel targets weren’t going to be very good for me. I started buying Arntzen targets but then I got more and more IDPA cardboard targets, practicing shooting at multiple targets at different distances. Then I got a wild hair to get a Dueling tree, shooting plate and Texas star. These targets got heavier and heavier and set up at the range got to become more cumbersome. So, I set up all of my targets in my backyard range. My range is about 400 yards away from my house in a gully. My backstop is a mountain.
I have a rubber dummy, various ducks, bulls, poppers, a swinging IDPA stand, etc.
In my backyard, I tend to shoot Suppressed so I don’t freak out the neighbors. Right now with winter, I long for light after work, less wind, and more warmer temperatures to pick up daily, like I usually do.
My point, is that you need to shoot more, and push yourself every time you go out. Beat the person you were last time you were out.
