my county's pistol clerk said that all barrels should be
registered....(added to our carry license, which lists all our
hand guns)
Just how exactly would you "register" a barrel? I have three barrels for my Glock 33. One has ZERO markings of any kind, one has a picture of a wolf and the stock barrel has the guns serial number on it. I doubt they're going to list "barrel with picture of wolf" and "shiny barrel with no markings" on my pistol permit.
Barrels are not regulated, uppers are not regulated....
Take a look in the SprtsmansGuide catalog. The thing is choke full of items that are completely legal and unregulated in NY state that they WILL NOT ship to NY. Why? Scared of the lawyers I guess.
If you want the 22 conversion and the retailer won't ship it then find one who will.
You also have to pay attention to the EXACT words used by these bureaucrats. The county health inspector says all kinds of things when he inspects my shop too. He starts his sentences with things like "I'd like to see...", "You should...." or "You have to...." The first two are "optional", personal preference on his part, the last one "You have to...." is health code that must be followed.
The is one caveat, however, if the kit comes with a magazine that holds 10 rounds or more then it cannot be shipped to NY.
Just called Kimber directly, because I was dying of curiosity to hear what they'd have to say.... short story, it is an "accessory", a "non-serialized part" and therefore unrestricted.
You can order directly from their website, BTW. The only downside is that they're actually located in NY state (Yonkers, I believe) so you have to pay sales tax.
