I’ve never seen an AD caused by this, but as I practice with a holster at every range session, I can say that it is worth being diligent and mindfully stepping through reholstering. I have on occasion caught myself with my finger where it should not be, shirt where I didn’t need it, etc. Slowly reholstering lets you catch that stuff without the annoying bang. And I have seen plenty of people doing the Paladin reholster just as the article described.
If you decock and leave the safety on before reholstering, this cant happen. Oh…wait…now I remember. These here hip youngsters dont like old fashioned stuff like hammers and safetys. So, ok then, you have to put up with the occasional “glock leg”.
