I think you're confusing heresay, like a report from your brother, with rumor. I know who I spoke with, even if I can only remember calling him "Scout" at the time. If you want to call me a liar, that's your perogative. That my Sr. Chief had a block failure on her base security sidearm 2 months ago could also be considered heresay.Actually Mr. Hand, if you cant verify it with names of real people, yeah, its a rumour or sea story. Thats the difference between news and a rumor. If nobody will go on record and say it, its not news, its a rumor.
I am incorrectly using the word toggle. I got it from another long forgotten reference and was using it to describe the alternating motion of the block, rather than comparing it to a Luger. I have a P5 and understand exactly how it works.
The following is complete gobbledygook:
1911s come in 10mm and many other ridiculously high pressure/high recoil chamberings. Locking block guns come in no greater recoil or pressure than 9mm and .40. You response actually seems to suggest that you think the locking block system is tougher than the Browning system that has been used to contain .357 Magnum forces. But you do seem confused about the action:The .45 acp has a low chamber pressure, roughly half of the chamber pressure of a 9mm. That is why the 1911 is so flat compared to other makes and models of guns...It doesnt have to handle that much pressure.
You are aware that the most accurate production (no hand fitting) autos are either the Browning tilt barrel Sig 210s, the Luger or a host of fixed barrel autos. The Army spends probably 10 times the expense of accuracizing a 1911 to get the M9 to shoot tight enough for their shooting teams. The modifications are extensive. That isn't saying that a Beretta won't shoot a reasonable combat group, but it is almost the last system to choose for match type accuracy. This is probably because the barrel and block aren't fully locked until the round is fired and the bullet pulls the barrel forward. If you know better, I'm sure the Army shooting team gunsmiths would like to speak to you.The advantage of the locking block over the browning tilting barrel is accuracy.
While speaking of reference material, where are you getting your "facts" about the Sig product? Rugers are investment cast, but that process wasn't being used for firearms in the early seventies. Sig frames are 7075 aluminum, which I also don't believe can be cast. So you might want to check that.
If you think the Brigadier slide is purely marketing, whatever.
My internet research was soully to see if anyone on the countless gun forums were reporting the CZ failures you believe in. I'm sure there have been some, but none that anyone is talking about. The important question is really whether the 30,000 round (or so) life of a 92FS is good or not. I say it is low, since there are several other guns that will shoot alot more than that, and quibbling about which ones is beside the point. Definitely by the Glocks, USPs and P210s, which are each capable of hundreds of thousands, rather than tens of thousands. Which other guns will also do that is a matter of tests and reports.
