My question.....Is grip angle a problem or more of an inconvience?
Bonus question....When did grip angle become a talking point?
Grip angle is not the deciding factor in any gun purchase.
Is it something I consider? Yes, but not so much for pointability as for recoil control.
First, I like the "steeper" angle of a Glock, since I grew up shooting a Colt Woodsman, a Ruger MK series, and so forth. They're very similar. But...
The steeper grip angle is also better (for me) for controlling muzzle flip. A squared off grip will cause a bit more muzzle flip than a steeper angled grip, all else being equal. IOW, a Glock pistol will put the recoil more into the web of your hand, driving straight back, while a lesser angle will put recoil all across the palm area, and the muzzle will rise easier.
And this is true of rifles as well as handguns. A straight stocked rifle will put more recoil into the shoulder of the shooter, causing more felt recoil, but less muzzle rise. A stock that drops down a bit, much like the old doubles or many shotguns do will put less recoil into the shoulder, but will cause the muzzle to rise more.
And in truth, it's a matter of preference. I prefer a bit of drop in the stock on a hard kicking rifle, but not so much that muzzle rise becomes an issue. On handguns that don't kick any harder than those chambered for today's common semi-auto cartridges, I prefer a steeper grip to allow for better muzzle control when firing.
I first saw "grip angle" mentioned as a "problem" here at THL. It's spread to other boards, I suppose, but I'm really not sure when or where it originated.
