A long post, but if you are interested in night sights - I suggest you read this:
These sights have two design flaws. Well, actually the P99 has a design flaw, but it's exasperated by two poor features in both Meprolight and Trijicon night sights.
1) The night sights are taller and larger.
2) The night sights are steel.
As a result, they stick up higher, and like to get hit more when tossed around in a bag/holster/whatever. And, being steel, they transmit the energy entirely through them, with no absorption. As a result, within all of 1 week of having them mounted, I snapped an ear off the sight plunger, which Walther made far too delicate and weak for a combat pistol (and which nobody stocks replacements for apparently. The original plastic sights, being smaller and absorbing plastic, don't aggravate this issue and so don't cause the weak ears of the plunger to break as readily.
Also, some following up on a couple other posts I made here, and some new discovery.
1) Just because the box says Meprolight ML18800 full sized P99, doesn't mean it actually IS product ML18800. I got a mislabeled package from Midway that really has ML18801, which is the compact version. We are going to see how well their return policy really works.
Why is this important? Here is what I ordered. Look closely at the foresight. Note how tall it is.
Here is what I got (but labelled as ML18800). Note how the foresight is shorter? See how the dot crowds lower to the base.
So that's why my night sights were shooting high.
Lesson from all this: Skip the night sights - they are more likely to result in your sights going out of commission, due to breaking the ear off the plunger. Usually such things happen at the worst time - I got lucky.
