just curious how many rounds of your home defense ammo do you put through your xd/xdm before your confident in it? 1 box of 20? 2 boxes of 20? 100 rounds? 200 rounds? when do you consider it a failure and would not use it? 1 jam in 50 rounds? 2 fail to fire in 200 rounds? must it fire a certain number of rounds flawlessly before you decide upon it as your home defense round?
