Perhaps I am oversimplifying this or just confused, but it would seem a firearm with a less angled grip (Sig, 1911, etc.) would require less of a muzzle-forward cant that a Glock to obtain the same benefits during draw, does that make sense?
And I agree with others who have pointed out that one has to be cognizant of gun access in the vehicle and interference ith entering and exiting a car and other activities before getting too radical with the gun angle.
Still, I do not like the angle of the stock Safariland holsters.
