Sorry friend,
But the Luger and Radom's don't count as Double Action autos. The Ruger P-85 series suffered from so many firing pin breakages that they had to go and redo the part, remember?
FYI the toggle link on the luger is not only prone to breakage, its also VERY sensative to sand and dust. There is a reason why a gun invented about the same time as the 1911 and the Smith revolver aint around no more, and its not just the 171 different machining actions that make it up.
Most modern DA 9s are designed to last 10,000 rounds, period. Many won't make that number. Some (Glock, Beretta, etc) will do more than that, but that is the general industry standard. Thats all the Military requested on those PDW XM9s too.
The Sig slide was designed back in the seventies to be cheap and easy to manufacture in quantity. Don't take my word for it. Look it up in the old Goerge C. Nonte Pistol guide.
The Beretta borrowd the locking block and open slide design from the Walther P-38. It also borrowed the high capacity magazine from the High Power and it borrowed the double action and decocking feature from Walther too.
Its a well thought out design. The frame and slide parts are fairly thick as well compared to other guns.
The locking block takes most of the abuse from the firing cycle.
The barrel stays in straight alignment on firing for better accuracy. The advantage of the high cap magazine is obvious. The designers who built this gun knew what they were doing.
I thought the conversation was about modern guns, not World War I souviners anyway.
The Star M-30 is a stud, but is it still even being made? I have nt seen one in forever.
I have a USP, and a Glock , but I am also not oblivious to recent reports of catastophic faulures in those arms too. Seeing as how the Glock biult its rep on durability, my guess is that folks are screwing up in the manufacturing end, not the design end. Ditto with the HK (albiet mine is a .40 and you cant hit the side of a barn from the inside with it, which is yet another reason I carry a 1911 .45).
As for the comments on military issue guns, just remember, the same military that issued the Peacemaker, the S&W Hand Ejector, the 1911, the Model 1917 Colt and S&W and the Smith Model 10 picked this one too. Thats pretty good company to keep in my book.
