Here is my method for air travel, so far smooth as silk.
1. I riveted an aluminum eyelet to the frame of my suitcase.
2. Utilizing the hard plaststic case my firearm came in from the factory I snap a "masterlock" on the handle.
3. use one of my better (brand name) cable locks, to lock my case to the eyelet in my suitcase.
I know the original question was where to find a suitible case, But I thought I would give up some food for thought first.
You'll want to use TSA locks on the pistol case. .
You'll want to use TSA locks on the pistol case. They usually want to open the case for inspection. When I moved out here I flew with my firearms and I did not use TSA approved locks, so they had to come get the keys from me.
Attention all passengers traveling with firearms. Please note the following:
Travelers may only transport UNLOADED firearms in a locked, hard-sided container in or as checked baggage. All firearms, ammunition and firearm parts, including firearm frames and receivers, are prohibited in carry-on baggage.
Firearm possession laws vary by state and locality. Travelers should familiarize themselves with state and local firearm laws for each point of travel prior to departure.
Airlines may have additional requirements for traveling with firearms and ammunition. Travelers should also contact the airline regarding firearm and ammunition carriage policies.
Also, please note that other countries have different laws that address transportation and possession of firearms. If international travel is planned, check the regulations of the destination country to ensure compliance with their requirements.
There are certain limited exceptions for law enforcement officers who may fly armed by meeting the requirements of Title 49 CFR § 1544.219. Law enforcement officers should read our policies on traveling with guns.
Failure to adhere to the following regulations will preclude passengers from traveling with firearms, ammunitions or firearm parts:
Travelers must declare all firearms to the airline during the ticket counter check-in process.
The firearm must be unloaded.
The firearm must be in a hard-sided container.
The container must be locked. A locked container is defined as one that completely secures the firearm from being accessed. Locked cases that can be pulled open with little effort cannot be brought aboard the aircraft.
If firearms are not properly declared or packaged, TSA will provide the bag to law enforcement for resolution with the airline. If the issue is resolved, law enforcement will release the bag to TSA so screening may be completed.
TSA must resolve all alarms of checked luggage. If a locked container containing a firearm alarms, TSA will contact the airline, who will make a reasonable attempt to contact the owner and advise the passenger to go to the screening location. If contact is not made, the container will not be placed on the aircraft.
If a locked container alarms during screening and is not marked as containing a declared firearm, TSA will cut the lock in order to resolve the alarm.
Travelers should remain in the area designated by the aircraft operator or TSA representative to take the key back after the container is cleared for transportation.
Travelers must securely pack any ammunition in fiber (such as cardboard), wood or metal boxes or other packaging specifically designed to carry small amounts of ammunition.
Firearm magazines and ammunition clips must be securely boxed or included within a hard-sided case containing an unloaded firearm.
Small arms ammunition, including ammunition not exceeding .75 caliber for a rifle or pistol and shotgun shells of any gauge, may be carried in the same hard-sided case as the firearm, as long as it follows the packing guidelines described above.
TSA prohibits black powder or percussion caps used with black-powder.
I plan on using big Disk locks just to keep them from cutting my .locks
You also need to check with your airline on whether you can pack your ammo with the firearm.
I flew SW a year ago and they do allow ammo in the same case. I had 3 loaded mags in the case that my XDm40 came in. Note: mags were not in the in gun.
