Trijicon H3 04 & H3 05 -- Which is higher?

Trijicon H3 04 & H3 05 -- Which is higher?
anyone have the actual vertical dimensions of both?

are there any other heights availalbe from trijicon?

[DJ Niner]

I believe those are manufacturing codes.

H3 is the chemical abbrevation for Tritium, which the sights contain.

04 and 05 are the years that the sights in question were manufactured. This is so the buyer and manufacturer can tell how old the sights are, as they have a fixed useful life (~ 12 to 15 years).

how do they identify the sight height?

[DJ Niner]

Glock uses a bar, or series of bars, located on the side of the rear sight. It may be one long bar, or a long over a short bar, etc.

I don't know the code(s), because I just happily use the factory-recommended sight for each weapon type/caliber. They have always worked just fine for me.

I think one of the popular Glock accessory websites had a list of the sight codes and their meanings; I'll keep an eye out for it, and post it here if I see it.

This is on Glockmeister's Meprolight Night Sight web page:

"These sights are available in either 6.5mm or 6.9mm heights, which we will choose based on the model chosen (unless otherwise specified).

The default size of sights per model are as follows:
The 6.5mm sights are for the G17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 37, and 38

the 6.9mm sights are for the G20, 21, 29, 30, 31 and 32."

thanks dj

i installed a 3.5 lb trigger pack and that actually made a difference in my groups - tighter
but still high

maybe in just need more experience with these 2 new guns?

are glocks considered to ahve a high learning curve to glock newbies as far as trigger control?

it does seem differen from my other double action guns
(in hammer cocted situation - smiths, sigs, HKs)

One long bar: 6.5 mm, short bar over long bar: 6.9 mm, two long bars: 7.1 mm, short bar under long bar: 6.1 mm.

There you go; I knew someone here would know the codes.
Thanks, Gary!

70SS454,

There are a couple of possibilities, here. If the gun was purchased used, it may be that the previous owner was having a problem with his groups being too low, and so he installed a higher rear sight. A friend of mine once bought a used G23 that had stock Glock sights on it, but they were not the "normal" height for that gun/caliber, so it does happen on occasion.

Second, it may be the ammo you are using does shoot abnormally high in your gun. If the ammo is near either end of the common bullet weight range for the caliber (very light or very heavy), it's pretty common for it NOT to shoot near the normal point-of-aim. Glocks seem to be less picky about this than some other guns, IMO.

Finally, yes, it could be a trigger control or anticipation problem by the shooter. Most folks that have group location problems with their new Glock seem to shoot low, or low and off to one side, but it is possible that you are flinching and/or grip-squeezing the shots high. To prevent this, I recommend lots of dry-fire practice, so good trigger control becomes a well-ingrained habit; and also watching your group size as an indicator of skill level. If you are shooting a small shot group in the same location time after time, this is a sign that you are applying the fundamentals in a consistent manner. If the group changes location or varies a great deal in size from one range trip to the next, then the fundamentals of shooting are NOT being applied consistently.

A high, firm grip on the frame and a comfortable shooting position are the building blocks of a good shot group. Double check for proper sight alignment (top of front even with top of rear, centered left-to-right in the notch). Hold the alignment as close as you can to the intended impact point, and while holding the sight picture, squeeze the trigger gently enough that the weapon fires without moving the sights. Repeat as necessary. :)
Warning: many folks squeeze until they THINK the Glock is about to fire (they feel the trigger pause and the pressure builds-up), then they jerk/snap the trigger the last little bit. However, with a Glock, the last little bit may be more that a little bit, and they end up jerking the shot off target. Squeeze it ALL THE WAY THROUGH; no twitch at the end.

If you are experienced enough not to need the helpful hints above, please forgive me for offering them; if not you, maybe they'll help someone else. Good luck!

i am new to glocks and appreciate all advice regarding all firearms even those i am proficent with

it is much easier for other to catch my errors that for me to see them

i am currently using blazers because the do have a high 875fps muzzle velocity and i pratice with them to simulate carry loads

i will try some fiocchi and winchesters to see if there is any change, all 230 gr ball

i have ordered 2 trigger kits, 3.5# from glockmeister and i think those will help

the g30 trigger isnt bad but the g21 is VERY heavy


i appreciate your input
