I was lucky to test the 25 and was just like the 19 but very soft on the recoil.
Also I notice the barrel tilds but still a blow back system.
No offense sir, But I believe .380 glocks actually don't have a locked breech, and rely solely on straight blow back. I could be mistaken through.All Glocks do it. In fact, most semi-auto pistols do it. It's called "recoil operated" and was developed by John Browning over a century ago.
Negatory.If the barrel tilts as the OP says that it does it's recoil operated. In a straight blow back system the barrel is fixed and does not move. Think Walther PPK, P22, HKP7, Jennings, Bryco.
Reference links please. I'd like to read and learn.Negatory.
Pretty much every source to be found points out that the Glock .380's are blowback operated.
The fact that they do not have a fixed barrel "think Walther PPK, Jennings, Bryco..." but a tilting barrel in a blowback system makes them unique.
