Back on track...
NCIS checks are not a good indication of gun sales or even interest. In most states, once you have a CCW you don't require another background check for your next purchase. Even in CT, once you have a CCW you do not need a background check to purchase. Interestingly, you can't purchase a handgun in CT without a CCW, but once you have your CCW, there is no background check or two week waiting period.
Even with one here in Va you get a check, cops get checked, you don't buy a gun here without getting a check. Pain in the rump but far better than the consequences.
