Thanks Zerodefect for bringing that up*. So is it the actual widths of the front and rear sights that are important to you, or is it the difference in thicknesses? The difference in width of your sights, will have a gap on each side of (0.150 - 0.125)/2 = 0.0125.
The sight I am looking at is the Trijicon WP101-C-600738. It has a front sight width of 0.144 and a rear width of 0.169, making a gap on each side of 0.0125, same as yours.
Thanks for the comments on color. It seems orange might be the best for me since they will probably be mostly used in daylight.
*(Moderators: I realize I am going somewhat off-topic by commenting on the subject of sight dimensions instead of color, but I felt it was important to me. Thanks.)
It's your thread. I think you can take it almost anywhere. Lol.
Front sight thickness is critical. Contrast extremes are key.
Nightsights only go down to .125 which can be kinda clunky for precision. But at night, things should be CQB, so precision isn't key. That's our trade off. I literally have a daytime Glock 23.3 and a nightime Glock 23.4. Because it's impossible for night sights to compete with day sights during the day time.
Optimal front sight thickness is .100-.115 on 4-5'' pistols. My 4" pistol is best at .105, I'd use a slightly thicker sight on a 5" pistol.
A Glock 23 with a .105" front sight has the same sight picture as a Glock 34 with a .115 front sight.
Keep in mind that light gap gets bigger on longer pistols. And a .115 will have a thicker brighter fiberoptic rod. I keep a Shapie marker in my range bag to darken the front fiberoptic if needed. And a lighter to try different colors, or even to use different colored bristles from a plastic broom. Sometimes white or an opaque yellow are best.
So at night you can reduce the clunkyness of a thick front night sight with a longer fullsize pistol.
Thin .090 sights are great for slow fire precision when teamed up with tight .125 rear sights. But I find this to be slow. The front sight is easy to lose.
A large rear gap is for speed. More light allows us to pick up the edges of the front sight better. As we move and wobble, our front sight should never hit the rear, no light gap. If it does it's harder to realign. Some shooters waste too much time aligning up the sights too well. A larger gap might upset them, but it'll fix that problem.
I've tried combining extra wide front night sights with extra wide rears, for a combo of night lamps, bright front daytime ring, and speed and precision.
And I failed wildly. It spreads our attention out too much. But it does work. It's just slow and messy. It functions, but it slows us down. On a Ccw it's an option, only if you can point shoot well, and never expect to fight at longer ranges. But if you can point shoot well, then maybe we should favor a thinner front sight for optimum use at longer ranges.
Where big dots excel, is close up speed. But we've learned to just point shoot at close ranges, which with training and competition, is far faster.
Sometimes competition pistols will use a thin gap and thin front sight, but they're using adjustable rear sights to ensure the point of impact is always above the front sight. Still this can be slow sometimes.
And as long as we're using shorter 3-4" CCW pistols, and assuming we have very good consistent grip and experience. It's nearly impossible for our front sight to be outside of the rear. So at night with a plain black rear. The shot will be high or perfectly on target. Any other misalignment, left, right, or low, and the front sight disappears. To get the front sight all of the way outside the rear, and visible, our wrist would have to be broken.
In pistol 6 training, all I did was concentrate on the front sight in the darkhouse. Never even bothered with the rear.
But unfortunately, longer fullsize pistols can be a pain with this technique. The longer the pistol, the more off course our front sight is, for every degree of error we make.
That's why we're seeing more and more experienced shooters with plain black rears, and a front night sight. It also cleans the picture up a bit, and makes that night setup a little bit closer to a daytime setup.
Warren Tactical has IMO the best night sights right now. Dawson fronts are equal. Sometimes the Sevigny Carry rear sight offers a better picture by blocking distractions. Sometimes the Warren tac rear is best for movers.
Bottom line with me is, our Ccw's are cheap. Get one for day and one for night.
