I love the way the muzzle of my g26 is beveled. I understand it aid's in holstering. Does it offer any other advantages? Is there a particular reason, aside from cost, that they only offer this on certain model's? I know the SC glock's have this feature and I've seen it on a G34 I think. Kind of like S&W did with the M&P line. Do people send model's such as the G19,G17 and such off to get a muzzle bevel? Thanks.
