The Welrod was a silenced, magazine fed Lee-Enfield (bolt) action pistol firing a .45 ACP cartridge.
The .45 ACP is subsonic, and the Welrod’s silencer fairly efficient, making it a very quiet weapon for a firearm.

I don’t like the extremely limited 12 shot lifespan of this pistol, but I love the 73 db volume. That’s what they portray in spy movies that we never come close to with commercial silencers.

Wow, hardly any misspellings or grammatical errors in your clickbait excerpt. I'm thinking plagiarism. Yep, looks like a cut-and-paste job, but Wikipedia is all I can find right now.

In any event, your plagiarism shortcut left you more time for your charming hobby of shooting your wife in the chest.

I have a little .22 silencer on a semi-automatic rifle. With sub-sonic rounds, the loudest sound in the bolt coming back.

that’s Mitchell WerBell III

In 1967 he partnered with Gordon B. Ingram, inventor of the MAC-10 submachine gun. They added WerBell’s suppressor to Ingram’s MAC-10 the “Whispering Death” for use in the Vietnam War

I wonder if this is the gun used in the film Munich where they assassinate the female character.
