I am looking for some input on the possible causes of a fractured lock block lug on a Beretta 92FS. This pistol is about 2-3 years old( It is used in weekly IDPA matches.) with about 10,000 rounds of mostly factory standard pressure ammo with mabe a few hundred factory +p rounds and never any +p+ or NATO rounds. I know 10,000 seems to be alot of rounds and have had part breakages with other pistol models with fewer rounds but I am curious as to any conditions ,other than just wear, that may be contributing to lug breakage.
Another question that I would like to throw in concerns replacing the broken lock block. I can get a block from Beretta with no problems but I am concerned with mechanical complications that I should watch for when installing a new unworn part into a worn mechinism.
Any input on this matter will be appreciated.
Thanks !!
