Looks like one of those hunkajunk RG's,If thats an RG on the grips.
The RG guns were the original "Saturday Night Special". At one time the RG-10 sold for $9.95 retail, and some places a buck cheaper, so you can guess how much they cost to make. On the plus side, quite a few cops and innocent people were saved because the bad guy's junk gun didn't fire. Fortunately, federal and state laws have eliminated the junk so that more cops are killed, which may have been one goal of the anti-gun movement.
In those days of mail order sales, a lot were bought by less than noble members of our society and the budding anti-gun movement went berserk. GCA 68 was one result, with its "point system" on imports and a ban on mail order gun sales.
Some of the anti-gun "scare" literature still rants about "cheap guns for sale at $9", when they are not raving about anti-aircraft missiles and H-Bombs being sold by the thousands at gun shows.
