Marking a barrel

I have a couple of barrels (1911) that do not have their caliber marked on them. Is it a good idea to mark the caliber with a punch set? The barrels are in pistols with a different caliber marked on the pistol. I know which is which but I probably won't be around forever. Looking for suggestions.

Acid etching may be an option.

Others will be along shortly with other opinions.

for most rifle barrels I use a simple punch set.. it does take some practice to keep everything in line.. one option I use on my fancier stuff is an electronic etcher
. I use this guy.... and an old Typewriter

Lol, the typewriters the tough part.

Typewriters the easy part. Just don't know what I am supposed to do with it

Have to admit it took some work to find one and the ribbon

You could stamp sides of lower lugs. Inexpensive and doesn't have to be perfect.

Find an engraving / trophy shop and have it engraved.

One of the slickest ways I ever saw to mark metal was when a friend of mine, the son of a gauge company owner, asked me if I could duplicate a step down transformer that they used to mark thread gauges. The transformer would drop 110vac to about 1 or 2 vac. By grounding the thread gauge and using a connected bit holder they could heat mark the gauges. Nice deep heat blue letters and numbers on tool steel. Since the voltage was so low there were no sparks.

I am thinking that is the way to go. I want it visible and professional looking.

What's a type writer?

One step above a type setter.

I used to go to one to get my linotype.

Good ole' electric pencil will do that just fine.  And you can mark them where ever you want Len.

I have an electric marker. I will use it on them some place that can't be seen but I need to get it marked so someone not taking it apart and looking for a mark does not try to shoot 9mm in the 38 super barrel. One of the barrels came marked but 50 rounds later the marking was gone. Whatever they marked it with didn't like heat. Thanks for all the advice everyone.
