Max- regardless of what you get, if you will be carrying it, then testing is a must. After all, lives are at stake here. My personal litmus test for any carry weapon is a minimum of 200 rounds of the carry ammo fault free. Any hic-up what so ever in that count, then we start all over at square one.
Other members here as well as fine trainers have similar tests/counts as well, but may differ some according to taste.
Just because you pick a larger, big name gun, doesn't mean it Will go bang every time.
Just ask Skunk about his Sig.
Good Luck
