Before you visit the gunsmith, you should call and discuss the calibers of the various guns you need checked out. Just to make sure he has the correct headspace gauges on hand for the basic safety check.
Be warned, if you leave a firearm with a gunsmith/FFL for more than 24 hours, they have to input the gun's information in their bound book. So eventually, despite not having seen the light of day since before the '68 Gun Control Act, those firearms will enter the BATFE database if that FFL ever shuts down, or gets raided for (fill in the "official reason" for the federal fishing expedition here), or... well, you get the idea.
Make sure the 'smith checks things out while you wait. If parts replacements are required, take the guns home until the parts shipment arrives.
Hey, it's not paranoia if they really *are* out to get you. ;-)
Hmmmmm.... didn’t know that.
Thanks for the info.
