The girsan is the beretta by almost all aspects. Same factory from what I heard
Actually the Girsan is made in a factory set up for the Turkish government by HK. All the folks working there are HK trained and all of the equipment is the same stuff HK uses. I've never shot the Girsan, but I have stripped both pistols, side by side. The machining quality on the Girsan was better (on the single guns I was comparing YMMV) and it had a much better DA pull, very much nicer than the Beretta.
