I've CCW'ed my P-64 for almost four years. Carried with round in chamber, safety off, in a DeSantis Nemesis pocket holster. Long DA trigger pull, got it in a holster, trigger always covered. Figured I was as safe as they come.
Frequently moving in and out of CCW prohibited areas during the day, I must have taken the holstered weapon in and out of my pocket over a thousand times while sitting in the front seat of the car.
The (correction: hammer) spur evidently caught on my pocket as I was putting it in my pocket, retracted the hammer 1/2 to 3/4 of the way, and then released it onto the firing pin.

The holster kept the barrel from being aligned with my thigh and it was angled away from my foot. Though the pants and the floor of the car it went!


Yes:
1. I am very lucky.
2. I am very grateful.
3. I feel very stupid.
That's all I've got to say.
