Fiber Front Sights How Often Do They Break?

[Fred_G]

At the Nighthawk Tour, I lost my fiber front sight with the first mag I shot. Mr. Bender offered some great advice, just look for the target color, and shoot. LOL

But, this is the 3rd time in the last year or so this gun (SA RO) has lost the front fiber. I rarely carry the gun, just mainly a range gun. My EDC has a fiber front sight, and gets a lot more abuse. Any thoughts on why this gun goes through fiber so fast?

I have plenty of fiber, I might remove the current fiber and see if there is anything in the channel that might be breaking them.

My current fiber has 2k rounds and many more thousand of dry fires and draws from a kydex holster.

This is why I wonder. I use leather for carry and range/practice. I think I will pull the current fiber insert out, and see if there is a burr or anything visible. If I see anything, will post up a few pics.

Tagged for interest. I've not yet had a fiber break. I keep extras and a lighter in my range bag.

Here is a good link and a 10-8 vid on the best way to install your fiber.

Great link PoolGuy

Would suspect the filaments are a bit loose or as you suspect, there may be a burr

The one that came on my PM38 broke after about 600 rounds. The replacement has lasted twice that long. I suspect the original may not have been snugged down adequately.

I will take it off, check for any burrs, and try that method AZP, Thanks.

Fiber optic replacement rods come in several different lengths and diameters. For example, my Ed Brown uses rods with a 0.060 diameter and my Wilson Combat uses rods with a 0.0585 diameter. Close, but not exactly the same. I'm still researching other manufacturer's specs for their fiber optic sight rods. STI is my next objective.

Quick followup. Nighthawk Custom uses fiber optic inserts (rods) with a 0.040 diameter according to their website.

I found some on the ebay, 1.5mm pretty close to .0585". I ordered a few flavors to try. Never saw one with a blue rod...

No visible burrs on the sight, I could not do it as neatly as in the video, but it is in with no movement.
