Yah, I appreciate that what I am saying is not easy to understand when described in words. And, some people like different things on their firearms. Not everyone will shoot their best with the same sights - but the numbers don't lie. You simply do not see anyone, anywhere, selling trapazoid sights for pistols (except Steyr, and even they are moving away from it now). The reason is because they are really hard to use, and are not used by anyone except hard-core Steyr fans. What I am trying to warn people of here is the obvious: something like 99.9% of the firearms community, firearms makers, etc. worldwide, have rejected the trapazoid pistol sights since they were first instroduced in 1999. Maybe a 0.01% group (or less) have turned the M-type pistols into a cult following type of thing. Buyer beware.
Here is a 1980s era Steyr pistol, the GB, from my collection. It is a lot more accurate and easy to use than an M-type pistol. Why? A big part of it is the sights. Even when looking at this photo your brain immediately recognizes that to hit the target dead on you will need to move the muzzle a little bit to the left - because their is more space on the left of the front sight than on the right. And this will work even if the front sight is raised up above the rear sight for a longer distance shot. You will not (likely) have this kind of immediate eye/brain/hand reaction with Steyr trapazoid sights. It will be lots of guessing, trial and error and frustration.
And here is a SIG 229:
If you want impact to be higher, or you are shooting at a longer distance - it is obvious what you have to do, and MOST IMPORTANTLY you are gauging straight lines vs. straight lines. You can clearly see, and remember, how much above the rear sight you had to put the front sight in order to hit the target at 25m, 50m, etc.
This kind of sight picture is easy to gauge, estimate, whatever.... and it is easily REPEATABLE.
With the trapazoid sights, you are dealing with angles that relate to other angles, and as you move the sights around the angles change. Making the kind of shot shown in the drawing above with trap sights, the rear sight actually partially covers the front sight, and you just have the tip of the pyramid sticking up over it, and the angles have all changed in relation to each other. If you find that easier, great. Have at it.
Lining the sights up like it shows on the logo on the box, yes that will work... at one distance, the one the pistol is sighted in form, as I mentioned above. But there are two big weaknesses:
(1) windage- instead of gauging a space on each side of the front sight, you've got these angles, and they only line up perfectly at one position (what the gun is sighted in for) instead of all positions, like a notch and post sight. If you are a little bit off, your shot will be off. The longer the distance of the target, the more you are off.
(2) elevation - instead of being able to gauge how much the flat front sight is above the flat top of the rear sight, you are judging how much the tip of a pyramid is above the top of a trapazoid. It sounds like it wouldn't make much difference, but for the vast, vast majority of shooters it is slower and less accurate.
I sold my M about 7-8 years ago, but I'm going to see if I have any photos of it on my Photobucket to try and illustrate:
This is the best I could come up with, with the Steyr obviously being at the far right (second from the end):
Steyr great company. Great products. They do have a bit of a reputation for getting wacky and/or not fully tested products into the market place. I like them, but the trapazoid sight thing is a total failure that people should definitely stay away from unless they have signifigant rounds through the gun past the initial "honeymoon" period.
