"Beretta then decided to use 5,000 semi finished slides, intended for the French, to build pistols for the U.S. military. Soon after the US accepted these pistols, a few 92F slides, (less than 10 total) and some older Beretta 92SB slides started to crack and fly off the frame.
An investigation would later determine that this lot had been made with French steel slides which were determined to be metallurgically inferior. Compounding this was 9mm Luger ammunition made in the US whose pressure far exceeded specifications. It was also discovered that the locking block required a design change to increase its service life. The US military decided to replace their M9 locking blocks after 5,000 rounds, which gave the gun a bad reputation on the civilian market as a gun with a short life. With the new version of the locking block installed however, the gun was a success and the locking block is now rated for 25,000 rounds. However, something still needed to be done to reduce the risk of being struck by the back of a slide if it should break. The solution was to enlarge the hammer pin head to act as a slide retention device. A shallow slot in the base of the slider is cut just long enough to clear the hammer pin head during normal travel, but arrests the slide's backward travel if the slide fails. This simple change resulted in the Beretta 92FS. Since then nearly all Beretta pistols are fitted with this simple safety feature."
"the gun was a success and the locking block is now rated for 25,000 rounds."
what is the locking block? can i replace it? how much for that part?
"but arrests the slide's backward travel if the slide fails. This simple change resulted in the Beretta 92FS. Since then nearly all Beretta pistols are fitted with this simple safety feature."
so this is only with the 92fs? my 92f will not have this? or are the newer 92f models have this as well? changing the lock block every 5,000 rounds would prevent a slide failure?
sorry if i dont make sense, i dont know what all these parts are yet.
i also have a ruger p89 with well over 10,000 rounds through it. should i be concerned?
btw, what would likely happen if a slide from a 9mm handgun came off and hit me in the forehead or eye? fractured scull or lost eye? death?
