I hate to beat TFO's to death but...

I have looked at these in person, and it seems like the front sight could rotate with use. (I had Trijicons rotate with a Safariland Raptor holster) Is this a valid concern with the TFO's? Is this true? Are there any LE agencies that use these for general issue?

Another thing, I know it says on the Truglo website that the sights aren't visible to the target. When in total darkness, do you see only the three dots, or do you see the whole fibre optic tube if you aren't looking straight at the back of the pistol?

Lastly, I have heard the criticism against FO sights in that they are supposedly more susceptible to chemical breakdown. I always take great care to clean my pistols with as little chemical as possible, and I generally don't get any kind of chemical on the sights ever (I just clean the soot off with a q-tip). However, knowing a good deal about chemistry, I know that solvents do spend a good deal of time in the vapor (gaseous) state, and since this is the case, theoretically the sights could become damaged by the gas.

Ideas, opinions appreciated.

My opinion: I don't think the front sight could rotate beyond a couple of degrees under any circumstances other than catastrophic failure of the mount hole. If you put a little red Loctite on the base and tang of the front sight that should preclude even slight rotation in guns with slightly oversize sight mount holes or sites that are slightly undersize.

I took my G23 with TFO’s into a darkened closet. At arms length in front of my face the gun had to be rotated to a bore axis of 90 degrees to my line of site to begin to see the glow at the rear of the front sight. Nothing at all was visible from the front straight on view. The same thing was true for the top and top frontal view. The pistol bore axis had to be rotated nearly 90 degrees down before I could see the glow at the rear of the front sight. So, these sights are not going to give your position away under any reasonable confrontational situation.

Vulnerability to chemicals: I’m not willing to torture test my most favorite sight set…:^) The light tube is well recessed below the metal of the sight frame and not particularly vulnerable to impact on either front or rear. Exercising reasonable care with my cleaning solvents, I’m hoping to get years of service from these sights.

Stevehof,
Thank you for that. Exactly what I needed to hear. I have pistols with every type of major night sight on it, and I don't "love," any of them. I am hoping that the TFO's will solve my problems, as they do for many.

I recently took the TN carry course from an operation called, "The Range Inc." and the instructor (who is an LEO) used them on his G23. He swears by them, and I could see the dots from the back row of the class. That caught my attention. I just want to make sure that they are going to keep working over the years until the vials burn out.

Thanks again for the direct answer.

Like I have said before, I will spend $100 on TFO's before paying half the price for any other. I live them to death, and shoot alot better with them. That is just MY experience though. If they are installed right then you should have no problems
