your first mistake was leaving a weapon in your vehicle, as opposed to carrying it on your person. this rule not only allows you the protection of 100% carry but also keeps you from arming criminals which to me is the biggest mistake a gun owner can make
your second mistake is carrying a pistol that you havn't test fired or "broken in" yet, average break in is 400-500 rounds
me personally i don't carry a gun until i've put 1000+ rounds through it, i don't want to carry something i can't rely on, espically when it's my life or the life of my loved ones
that being said, any gun is better than no gun
