here in Missouri anyway if you get delayed then they call you back you have I believe it's 30 days to go pick up that particular firearm listed on the form. if you don't go pick it up within 30 days or you want a different firearm than that listed on that particular form they will do another background check. CCW in Missouri as it's called has no effect on this. Personally I wish it would be like some states in a CCW you wouldn't even fill out the form.
