DenverSteve: Makes a good point, I have been upside down 2X at 15 mph backwards, 40 mph backwards, barrel roll, end over ( black ice ). My Sigma remained in my Kramer holster both time as did the 2 mags in the Kramer pouch, but I got hit with dirt, glass, almost by maglight ( which is now secured in all vehicles) book, tissue box. Basically nothing hard and heavy hit me in a soft spot. I will admit to tucking a j frame in a holster in the drivers side map pouch for easy access when I am plowing snow, since the Sigma is under the snowmobile suit. There are places to put firearms locked in a vehicle, talk to your local PD. Be Safe,
