Question 1

Why do frequent flyers choose the MonoShaft over a generic TSA lock?

Accepted Answer

The CMFF MonoShaft uses a single-piece hardened shaft instead of a shackle, so there is nothing to pry or clip and no weak hinge point. For a traveler who flies with a firearm dozens of times a year, that means a predictable check-in every single time and a case that comes back intact at baggage claim.

Question 2

Is the MonoShaft TSA-approved for flying with a firearm?

Accepted Answer

Yes. The MonoShaft is designed for TSA-compliant firearm check-in. You lock the hard case yourself, retain the key, and declare the firearm at the airline counter. The MonoShaft geometry fits standard lock holes on polymer and aluminum gun cases used by most airlines.

Question 3

How many MonoShafts do I need for a single hard-sided gun case?

Accepted Answer

TSA requires the case to be locked with a lock only you can open. Most travelers use two to four locks, one at each corner of the case. The MonoShaft 4-Pack ($44.95) is priced for travelers who want a full set from a single order, while the 1-Pack ($19.99) is useful for replacement or a second case.

Question 4

What happens if TSA needs to inspect my firearm in checked baggage?

Accepted Answer

In the rare cases TSA requests an inspection, they will page you at the counter before your bag is loaded — you unlock the case in their presence. The MonoShaft keyed cylinder opens and relocks in seconds, so you are not holding up the line at the gate.

Question 5

Will the MonoShaft fit my Pelican, Nanuk, or airline-rated hard case?

Accepted Answer

The MonoShaft was designed around the standard padlock holes found on Pelican-style, Nanuk, SKB, and most polymer airline-rated hard cases. The shaft diameter and length accept the common 7–9mm hole spec used across these brands.

Question 6

Does CMFF offer a color option so I can spot my case faster on a carousel?

Accepted Answer

Yes. The Red MonoShaft 2-Pack with Black Case ($45.99) gives travelers a high-visibility red lock body that is easy to spot on a crowded baggage carousel, plus a compact carry case to keep the keys organized between trips.
