Knowing your gun is important to accuracy. Having a proper sight alignment and sight picture is part of that. Sight alignment is the proper positioning of the front and rear sights, while the sight picture is the placement of those aligned sights onto the target. The next question I have for you is where on the target do you set your sights on?
This depends upon your sights and distance to your target. Best way to see how your gun fires is to use your battle sight and see where you hit the target consistently. This will tell you where your sights are set.
Which sight picture do you use and with what gun? And at what distance?
Depends on the firearm. I can never remember, so the first few shots at the range are a reminder. I wish that they’d set them all the same from the factory.
All mine are combat sight picture except for my 1911 which is 6 o’clock. Center hold makes no sense to me.
Edit - I said that backwards. My 1911 is center hold, 6 o’clock make no sense to me.
To be honest.. I’m too old to iron sights thinking… Red dot in center hold at 10 yards… then you have to know the offset and what bullet you’re shooting.
In my case 6 o’clock hold will be at around 50 - 60 yards.
The scales on my back are small and easily clear most doorways.
Rear sight. Important for 25 yard match. Not so much for defensive engagements. They happen fast, with little time to prepare and historically at shorter ranges. A repeatable grip and stance will ensure sight alignment, hence “target, front sight, press”. The only way yet discovered to get that repeatability is practice, practice, practice.
