The post on Your Friend's Course of Action and the fact that I have been looking on some forums for a used gun, a hobby of mine, looking that is, got me thinking.
I read posts that state that the gun was their CCW and has 0 - 50 rounds through it or that they have carried it for X years and there is less than 100 rounds use.
Not setting myself up as an example but:
My first carry gun was a 1911 and I was taught that it had to have a minimum of 300 rounds to break it in. I always shoot a minimum of 300 rounds through anything I intend to carry, and if it malfunctions, more. I also tell my students that they should never carry a gun that they aren't sure will work. I do this for anything that will be used for SD on my person or night stand regardless of the manufacturer. Why on earth would someone trust their life to something untested.
Second, how could you possibly be ready to defend yourself when the SHTF if you don't train or practice with what you carry. Even if you have multiples of the same model, that doesn't mean that they will function or aim the same.
How much do you shoot the gun you carry?
