The largest reason Glock is currently leading in LEO holsters is the price structure. They are adequate in reliability and accuracy, and non-shooters can be taught to qualify with them under LEO training standards. Did I also mention that purchasing agents love them because they are CHEAP.
The Glock grip-angle is counter-intuitive to anyone who has even a passing familiarity with shooting. Yes, you can be taught to shoot them well enough to pass qualifications. You can also be taught to pass qualification s with a 12 ga. shotgun, so what?
If you want a pistol that sets lower in the hand, try that CZ that you so despise. I've heard CZs called a lot of things, but NEVER poor quality, especially when compared to a Glock.
As for the XD's grip safety, it's all in what you want. Calling it useless is much akin to lauding the grip angle of the Glock. Neither one actually does anything meaningful, they just are.
I've tried to like the Glock over the years. I CAN shoot them fairly well, but I have to actually work at doing so. The last thing that anyone needs is to have to concentrate on the gun, beyond the sights, in an emergency. I find that the Ruger SR9, and SR9c, and the CZ 75 all come naturally to a useful sight picture, even under stress.
The OP wants something else, not another sip of Kool-Aid. Let him go.
