Private Sale of Firearms

Pistols and Revolvers
Federal Law states you may only buy a handgun in the state in which you reside.

You can only buy a handgun in Connecticut, if in addition to being a resident, you have a valid Permit to carry Pistols or Revolvers, a valid Eligibility Certificate, if you are a licensed Firearms Dealer or if you are a Sworn Police Officer.

A DPS-67-C and a DPS-3-C (4 copies) must be completed. The seller of the handgun must contact the Special Licensing and Firearms Unit at (860) 685-8400, or 1-(888) 335-8438 and obtain an authorization number for that sale. This number is to be added to both forms. The DPS-67-C is to be retained by the seller for 20 years. The seller should retain the original copy of the DPS-3 for their records, give one copy to the purchaser as a receipt, submit one copy to the local police authority where the purchaser resides and submit a final copy to the Commissioner of Public Safety.

I've done the transfers several times with handguns! Very easy to do! You basically call up DPS, give them the permit number of the buyer and seller, they give you an authorization number to record on your paperwork. Then fill out the paperwork and send it to where it's supposed to go! DPS 3C; seller keeps one, buyer keeps one, one goes to the PD in the buyers town, the other gets mailed to CT DPS in Middletown, CT. Seller keeps the DPS 67C.
