A good holster is nice to have.
With a Glock a good holster with the trigger guard completely covered is nice to have. Back in the 1990’s the county sheriff over from us like to carry his chambered glock in his pants pocket without a holster. Well you can guess what happened. One day he stupidly carried his car keys in the same pocket and he reached for his keys and Barney shot a hole through his foot. He was a raging diabetic and nearly lost his foot for his stupidity. Barney lost his very next election...
