What's a lug?

[Dennis]

I've heard the expression full and 1/2 lug - what's a lug?
Thanks.

My guess is the steel under the barrel of a revolver. A GP-100 has a full lug. A Red Hawk has a half lug. My understanding it adds weight to the barrel to help tame recoil.

that housing under the barrel of a double action revolver. Ones that are as long as the barrel are considered "full lug". From there you have 1/2 lug and sometimes 3/4 lug.

Technically, those are ejector shrouds, or ejector rod shrouds. It has become common to refer to them today as lugs, or under lugs, or under barrel lugs, but they are really shrouds.

This is an under barrel lug. Its purpose is to provide a forward latching position for the front end of the cylinder rod, particularly on a S&W revolver. Colts don't have them, they lack a way to latch the cylinder rod at the front end, the rod just hangs free. The purpose of a shroud is to protect the cylinder rod. A lug does not offer much protection to the cylinder rod.

Full Lug

Half Lug

Perfect example!

Thanks for answering my question. Thanks for not laughing.

 

[wixedmords]

Dennis, those are good questions.

 

[Cholo]

I can show you the other extreme of a gun that doesn't have a lug or any kind of shroud :wink:

 

[Driftwood Johnson]

Yup, like I said, Colts, including that Police Positive, did not have locking lugs at the front of the cylinder rod. Only latched to the frame at the rear.

Wow, you learn something every day on RugerForum.
By-the-way, "NUG" is gun spelled backwards.

...JImbo

 

[ctkelly]

And dont forget about them wheel lugs.

 

[CraigC]

You either have a shrouded ejector or a full underlug. No such thing as a "half lug".

 

[Beruisis]

All 3 of my brother-in-laws are full time lugs.
