Uh yes it does... Grip angle affects everything including how much you may or may not have to adjust to the particular weapon being fired.
Would you say reclining the seat in your car more or less or doesnt affect your comfort or the safety of your driving?? Its the same idea.
This is the notion that the OP has steadfastly refused to "get," so much so that this entire topic is set upon the horns of a false dilemma.
"Real problem or individual choice?" There's no compelling reason offered as to why it cannot be BOTH.
He then goes on trying to continually divorce the Glock's grip angle from its overall feeling of "fit," merely because he
wants to adapt to it. The Glock's built in back strap hump which he'd attribute to the "fit" column is in fact a facet of what creates the overall grip angle. The fit and the angle are only capable of divorce through a grip burning to make the Glock hump go away.
For those who
don't want to adapt to the Glock's rakish angle, the "problem" minor though it may be, helps to trigger an individual rejection of the weapon as less suitable to one's preferences than another.
Frankly, his position in this "debate" is ridiculous. Perhaps because I am left handed I have a better understanding of rejecting firearms for forcing me to adapt to them rather than having the firearm being adaptable to me.
For instance, one of my faves is the 1911, In its standard configuration, the safety is only on the left side of the weapon, forcing me to swing my left thumb over the back end of the pistol to disengage it. According to the OP, this is not a "fit" issue, as the pistol fits just fine and is totally usable, it's an adaptability/laziness issue. What is actually going on is a "REAL" problem, that of inconvenience in use, that is remedied by picking a 1911 that has an ambidextrous safety as standard or by "changing the weapon" to suit my desires to have a more usable safety lever, "an individual choice," since
some southpaws don't even bother. If a 1911 were not able to be safely fitted with a safety lever on the "wrong" side, I wouldn't own one for love or money.
Somehow, the OP refuses to understand that choice can be built off of a perceived problem that is very real to the individual. I am a more efficient and better shooter with a 1911 that is adapted to my handedness, though I have in the past readily adapted to one that was not.
Given the choice to shoot a Glock, which has both a grip angle and a bunch of other ergonomic choices I do not like, nor want to adapt to, and a similar pistol, say a M&P, which gives me the choice to have things my way, the OP assumes that I am just being lazy in not wanting to warm up to the Glock rather than to reject it as unsuitable to my personal criteria for a worthwhile sidearm should be.
I had a department try to shove a Glock into my holster twice on the cheap, so the "problem" of not wanting to adapt to a whole bag of suck was very real and concrete to me. Oddly enough, I wasn't alone in that we managed to get a list of approved sidearms created that provided alternatives. I can only guess that about 35 percent of the deputies were just being petulant and lazy for holding out for something that worked better for them individually?
