I agree... this is a great idea. There are so many acronyms in the firearms world, it’s hard for me to follow some posts. Good work!!!!

Prayer Warrior, I've found myself coming back to this thread at least four times since you posted it. The reason is that I still seem to run across so many acronyms that I don't know!

One thing I just got finished doing (literally, just moments ago) was to copy-and-paste your whole list - both halves - into a Word document. Once I print it out, I plan to keep it on a clipboard hanging onto the wall next to my computer screen, at my office desk.

I should add that one addition I made was to add "ACLJ --- American Center for Law and Justice" to the list, preceding the ACLU because of alphabetization. Which inspired a question for you...

Can your list be made to be added to, so it can be always current with suggestions (as long as they are seen to be valid) instead of static? Just wondering, that's all.

But as it is, it's the most comprehensive list of acronyms I've seen for the gun world I've ever seen!
Thank you for the hard work you must have put into it!

Hey PW, how about BTF? I saw it in the articles section, "Glock 19 Gen 3 Mods to solve BTF issue". I read the article, and I still don't know what BTF means.

BTF= Brass to Face.
Added above.
OK, that makes sense. The article was about the ejected casings hitting the article's author in the face. Ouch! Thank you PW.

While I was adding OEM (noted above) to my own copy of Gun Related Acronyms, I noticed something "questionable" ... the entry "OOPAWW". Nowhere in the explanation do I see what the individual letters "OOPAWW" stand for. As usual, I'm probably missing something... ??

EDIT... oops, I see that the original entry is "opaww", not "oopaww".

What is RSA? I'm assuming "recoil spring assembly", but it's not on the acronym list.
Also, I'm still waiting for opaww to get explained what the letters stand for.
