What holster?
Carrying Mexican is dumber than aiming sideways like a ‘banger.
For a ten year period of my life (1990-2000), a Glock 17 was the assigned weapon of the unit I worked with, and during that ten years, I witnessed more unintentional discharges of Glocks than I have time to list here. To carry that Glock was like carrying a Colt 1911 with a round in the chamber, cocked, unlocked, and the grip safety taped down. At the time, no sane person would have carried a Colt 1911 in that condition, and I doubt if anyone would today, but they’ll stick a Glock in their pocket and away they go.
I eventually became comfortable carrying a Glock, but I never became completely comfortable around others who carried Glocks. Every time I started to get comfortable, another unintentional discharge would occur.
