***We used to say that RG stood for “rotten gun”. They were probably the worst guns ever imported.***
Two other makers of trash guns were EIG, and IMP (Imperial Metal Works.
Quite a lot of the Spanish made guns were real junk. STAR pistols seemed to be ok.
Many of the Spanish revolvers looked just like a S&W. Look close and you will notice in real small letters, made for the SMITH & WESSON cartridge. Smith and Wesson is in real big letters.
When I was around 15, a school mate sold me a PIC .22 revolver for $10. The PIC stood for Precise Imports Company but that was not a very good description of it’s quality.
I actually knew it wasn’t a very good revolver but just wanted something to say I had a hand gun. Nearly 50 years later I still have a tiny fragment of lead in one of my fingers near a knuckle. I tried to shoot it two handed when I felt a real pain.
That thing had shaved a bit of lead and sent it right into my finger. I tried several times to get it out with a needle but it was in too deep.
I think the PIC and RG were about identical.
I sold it to my Brother and I can still remember him carrying it on his hip like a gun fighter. Despite it’s horrible quality, it wasn’t totally worthless. I could hit an old chimney from around a hundred yards with it. I could see the little puffs of smoke when it hit.
