New G34 and TFO's?

[gtmtnbiker98]

Bought a new G34 and had TruGlo TFO's installed. With so much void real estate underneath the front sight, will the front sight hold since it hangs over the slide cutout without support? What my main concern is stems from repeated draws from a BlackHawk CQC holster during IDPA matches and the potential for snag.


Thoughts, opinions?

I shoot the same set up and the front sight requires care and feeding. I recently replaced my front sight and used a drop of metal bond on the blade where it made contact with the slide, then used blue loctite when I screwed the hex nut down. Repeated drawing and use, caused my first sight to become loose and wiggle left to right about 1/8". I think some of this was from the post edges becoming rounded so regardless of how tight I made the hex nut, it was loose in an afternoon.

Aside from your specific question, I also ended up with a loose light pipe that I had to use a drop of super glue on to reseat. I think this may have effected the glow, so I sprung for a new set to replace the front sight. Interesting, you cant purchase a replacement front sight, you have to buy a set.

I still like the sight picture better than some of the other sights so I am working with these. Ive got about 7K so far this year with this set up.

Thanks, I will be extra careful. After my first outing, I noticed that the black finish on the rear sight isn't that great, already showing some wear. Do all TruGlo sights show this amount of wear so quickly?

Some wear a lot and some wear a little. I have a few of both, and the wear isn't proportional to the use on the pistol. On the plus side, the one I have with the worst finish still doesn't show any corrosion.

TFOs still have too many quality issues to suit me. That, and the crappiest warranty going!

To buy a trouble-free gun like a Glock, and then fart around with ultra sensitive sights, just doesn't make sense to me.

They're a very cool idea with a long R&D row to hoe.

On my initial outing, I noticed that the sights were shooting off to the left a tad and was exaggerated the farther back I went. Of course, the sights were initially installed centered. Took them to the local smith and he bore sighted the pistol and had to tap the rear sight way to the right to center my point of impact. I would venture to guess that my rear sight is 1/8" off center, now. At least the G34 is hitting point of aim! Why do Glocks shoot left, has anybody ever figured this out?

Trigger finger

[gtmtnbiker98]

I've been shooting just a little longer than that to know that it's not the trigger finger, but thanks. Just bought a G34 and mounted TruGlo TFO's and centered the sights and the POI was left and had to drift the sight right to correct. Never had this problem before until these sights.

Understand the question. Ive had some luck with a laser borsight at the range setting up my sights, then adjusting to my own POA. You can adjust your sights for your habits. There are various views about that on the boards. Good luck with your diagnostics.

No, seriously, it's trigger finger.

I'm a lefty, and shoot with 2 other leftys at IDPA matches. They also own glocks.

If a lefty has issues with a Glock, the gun is shooting to the right.

It really isn't the gun.

It would be valuable to slip a LaserMax into, or a Uni-Max onto, that G34 of yours, and have an astute observer watch closely during firing. Lots of questions would be answered immediately.

Your right about this but.... doesnt the bullet hole accomplish the same thing? :)

[gtmtnbiker98]

I ruled out trigger finger by shooting two-round groups at various distances. At 7-feet the pistol shot about 1" to the left, at 14-feet it was off to the left approx. 1.5", and at 21-feet the pistol was shooting about 3" off to the left.

My target was two pieces of tape configured as an 'X' and the shots were getting farther from the center of the X as the distance increased. Now, when I was shooting up close, of course, the shots were barely off, but going back to 15-25 yards, you can really notice that the sights were off. I never experienced this problem with my other Glocks but then again, they all have the OEM factory sights.

The sights were confirmed by our firearms instructor who is an avid shooter and he received the exact same results. After tapping the sights, the pistol is now shooting as accureate as the others in the stable. I just wonder what makes the TruGlo sights so different as to cause me to behave like this? I'm sure it has something to do with the Indian and not the arrow.

I always have two reactions to stuff like this:

1) I'm sorry for the guy that just wants to shoot and have fun! :sad:

2) It's an interesting problem... :headscratch:

sidewinder6, I see your point. ;)

I just thought a laser might prove expedient.

Starting at, say 30-feet, using a LaserMax or collimated Uni-Max (tested on another gun), we should see the bullet hole appearing just above the red dot. With the TFOs dead-centered, where is the shooter's sight picture, compared to the laser dot?

Hold the laser on target. Watch that red dot closely as the shooter fires the weapon. Do his hands do anything funky? If not, and it's a "hit", the bore axis of the gun is fine, and the problem's with the sights, or the shooter's interpretation of them. If the laser dot moves left on firing, it's the shooter's trigger technique.

Just curious, what is the color configuration of those TFOs of yours? All green? Green rear, yellow front?

Try cutting black tape neatly, and covering those rear light pipes, leaving only the front glowing. Try again at the range, adjusting as necessary. Any improvement?

I agree, RayB. I had a gunsmith adjust my rear sight using a bore sight and he confirmed that sight being off to the left even though the sight was centered within the dovetail. Oh well, all is fixed.

I've shot Glocks since the late 80's and own several and have never had a sight alignment problem until now with the TruGlo sights.

I am glad I found this thread. I am looking to buy a G27 with TRUGLO sites. Now, I see above this brand may not be the way to go. Can you all advise me of which brand glowing night site is the best to compliment my G27. I am thinking to buy a Blackhawk CQC Serpa Glock 26/27 (Black) holster to hold it. Thank you in advance best and brightest!
