Thank you for clarifying.
I do think for many the grip angle of the Shadow Systems may be more "normal", and at first I thought that too. What was interesting was over time I found I tended to end up with the pistol pointed high when drawing from concealment, whereas I didn't as much with my standard Glocks. I tried the backstrap that was supposed to more mimic a regular Glock, and that helped somewhat. I like the Nomad style of aftermarket frames a bit better. It has basically no hump, but the back of the angle is more vertical than the Shadow Systems. I find with the angle of the Glock the hump actually helps me.
The trigger on mine was never very good. Mine was actually notably heavier in pull weight than the stock Glocks I have had. When I had to send my MR920 back to the factory to have some issues resolved they replaced the connector and that made it better. The reset on the pistol did "feel" shorter than a stock Glock and I seemed to shoot it very well at speed, that I miss.
My hands have never been big enough to get bit by the slide on a Glock, though the Gen 4 and Gen 5 models do come with backstraps with and without beavertails from the factory. The trigger guard has more room, which is nice, as are the sights (though you can get Glocks from the factory with night sights). I did like the grip texture, though I found with time that the texture would collect dead skin (if that happens use a nylon brush and give the grip a once over). I know some people are bothered by the hollow at the back of the grip, it just never bothered me personally.
Enjoy your pistol!
