Yep , I've had an Astra 600 , a few of them actually , for over 30yrs. Actually one was my first centerfire auto-pistol. Bought it from the man who bought it thru an Interarms mail order ad for $19.95 back in the 60s.
So much for a 9mm Para needing a locked breech , this blowback pistol works just fine , and is accurate and reliable to boot.
Star also supplied some Model Bs to the Third reich too.
Waffenamt-marked Spanish pistols bring several times what an unmarked pistol does. As a result , there are many fakes out there.
