Hello all, I originally registered as "Armorer" the user name I use at my website, then decided to go with my real name, which I use most everywhere else.
On the subject of sights, tritium and otherwise.
I can definitely see a situation where illuminated sights can be of DEFINITE advantage, and can see almost no circumstance where they can be considered the CAUSE of a problem.
My standard loadout most days is a Kimber Ultra Elite with night sights and a Surefire 6Z light. Using the light to illuminate the target, and the nice little green dots on the sights, I can engage the targets out to 50 yards just as well as in broad daylight.
I fail to see how that can be a problem and while I'm sure that certain "Greats" of shooting history could point shoot to that degree of accuracy at that range, I doubt that 1 in 1,000,000 shooters could do so.
Anyone who has spent any time at all hunting is able to relate to the situation at either dawn or dusk, when it is possible with available light to clearly identify his target, and count the points on that buck, but has not light enough to clearly see his sights. Are not the same lighting conditions possible in a defensive situation?
As to the argument concerning fixed/adjustable sights, my preference is fixed sights on a defensive pistol, adj. on a target gun.
Why?
For defense, I carry one load and ONLY one load. I do not change it, it never varies.
For that reason, adjustable sights are "teats on a boar." Totally superfluous.
On a target gun, I may experiment from time to time, looking for that "ultimate" load that will let me poke ridiculously tight groups in a piece of paper a ridiculous distance away. My life does not depend on it, I'm willing to play with it a little bit.
Have I seen adj. sights break DURING a confrontation? Nope! However I've seen them break in practice or training, and to assume that they will break then, but not at the crucial moment is folly.
The Elliason sights mentioned by a previous poster were notorious for this, due to the fragile roll pin, and there is also good reason why S&W sights are no longer installed on 1911s. They're just a little too delicate. Not especially delicate, just fragile enough that users are not comfortable trusting them. (Although I will admit, I love the looks of them on a vintage Swenson or other of the same period.)
Far more likely than a breakage, is that the sight be knocked or inadvertantly knocked out of adjustment. True, the same can happen to fixed sights, but the odds are significantly less.
The flawless, perfect, guaranteed never to malfunction pistol has not yet been built and probably never will, so lacking that, we try to stack the odds as much in our own favor as much as possible.
Isn't that what it's all about?
