Fiber optics are very commonly used in bowhunting sights and durability has not proven to be an issue there. While bow sights don't have to deal with the recoil factor, I can assure you that they are as roughly treated as a firearm in the hunting fields.
Only problem I see is that eventually the fiber optic rod will break and fall out of the sight. It's easily replacable, but I hate to be looking for it in a high stress situation and not be able to find it. It's happened to me in competition, and it creates a confused hesitation that would not be a good thing in real life. (as compared to the game)
Just an opinion, and I'm no expert. Came to me the second time mine fell out :smile:
I guess if you don't change them regularly anything could happen...I change mine everytime I clean the pistol...Just maintenance, like everything else...I can barely get mine out with tiny needle-nose pliers and usually drive it out with a tiny pin...Guess all sights aren't created the same :wink:
The fibre from Brazos is incredibly bright and he has the correct sizes. I'm not sure how many sizes there are, but I think he sells at least two....060 and .090? Not sure on that...Check with him at:
My sights have a support in the middle to better hold the fiber and to protect it from breakage. The sight holds up well just make sure your holster has a track for the front sight. The fiber is easily replaced. I have 0.060 and 0.040 diameter replacement fiber.
