Natural point-of-aim doesn’t exist? Interesting
Not to flame anybody, NPA has as much to do with foot placement, hip angle, shoulder extension, etc... as it does with whatever bow you're holding. That's why you shuffle your feet to recheck your NPA, especially on long guns. You're moving your presentation to your NPA, not the other way around.
I get what you're saying, but the difference isn't NPA, it's presentation. For you, the glock grip angle just results in a less perfect presentation based on your current training situation. Could be grip angle, hand size, finger length, grip cant, support hand pressure, finger grooves, sight height, head angle, eye angle, etc... any of a myriad of factors. Besides, if you're looking at NPA for anything other than a quick check with a combat handgun, you're mixing games.
Glocks are definitely not bullseye guns, but they aren't built for that. Glocks are built for a dark night in a parking lot in the rain, when you've already been knocked on your ass. The worst scenario. And, they will work. That's why we give them out to every countries police and military force all over the world. Mags are cheap and almost indestructible.
But, the earlier post about times changing is entirely correct. We used to have pistols with major QC or ammo issues. I wouldn't carry 9mm for years because I'd seen too many folks walk off after getting hit with it. I wouldn't carry certain handguns because I'd seen too many stovepipe and stoppages caused by poorly made products or magazines. Those days are gone, because the market won't tolerate it. Any of the major brands make quality products now, even the frequently bashed "plastic pistols".
Pick whatever tool works for you and shoot the crap out of it; shoot it one handed a lot, shoot it while moving forward-backwards- and at angles ( get off the X). It's all about presentation, presentation, presentation on a combat handgun. The grip you have when it leaves the holster is the grip you have to work with and it goes from there. And, your presentation drives your speed and relative accuracy. Handguns are defensive tools made for critical engagements, we don't run out of distance or ammo, we run out of time.
Glock ? Sig ? CZ ? Smith ? I like them all. Some I shoot better than others, some carry better for me than others. I agree with the earlier poster about being able to pick up anything and run it, especially at handgun distances.
Sorry for the rant.
