How do internal locks work?

[MattC]

I've read a little about internal locks, and the controversy of how they can be knocked loose or fail and suddenly lock a gun. However, how do these locks operate? What do they lock and how (please pardon my ignorance) does the user control the lock?

Internal locks are different with each gun manufacturer. All, (I think) are "operated" by the user, typically with a small key-like device. Some folks disable them. Some folks won't buy a new gun with a lock. I only own one and it's NOT my carry piece and it's NOT a home defense gun. Highly unlikely I will ever buy another with a lock.

OBTW, the short answer to the question, "How do internal locks work?" is:
Quite well most of the time - which is okay if you only want your gun to work most of the time.

"How do internal locks work?"

The variety that are found in Smith and Wesson revolvers work by infesting the brain of S&W purists, giving them the disposition of a bear with a toothache whenever the subject is raised.

Operation varies by mfg. 1911 types often use a locking mainspring housing that blocks the hammer spring from being moved down by the strut. S&w block hammer rearward travel. Both operate by a key.


I think the real answer is internal locks work to add several completely un-neccesary pieces to a gun all of which may or will break when you can least afford it or be mysteriously locked. Further, they just build a false sense of security.

"Don't worry, it's not loaded"......Booom!
"Don't worry, the safety is on".....Boooom!
"Don't worry, the internal lock is on".....Booom!
"Don't worry, it's unloaded, the safety is on, and the internal lock is engaged"......Booooom!

Insert bleeding and profuse apologies to dying friend/family member here.


All guns are always loaded. Carry them or put them in a safe.

As far as safeties, external locks, internal locks, smart guns, etc. It is a gun, it is not safe.

Nothing works nearly as well as just keeping you finger off the trigger!

If you own the gun....

and have the key, yes, you control the lock. My Steyr S40 has a key lock but I have never used it. I just keep my finger off the trigger until I am ready to shoot. I don't lock my guns at home either because my wife and I are the only ones there, and we take them with us when we leave the house. If children cannot mind their parents, they are not allowed in my house. But, we don't know anyone near with kids so it is not a problem.....chris3
