SIG Broken Frame
From the book; “ Gun Digest Book of the SIG SAUER “ 2ed by Massad Ayoob, 2014, page 243.
“ The SIG armorer’s manual even makes a point of stating in caps,
“SPECIAL ATTENTION MUST BE GIVEN TO CLEANING THE EXTRACTOR “.
“ Particularly if you have an older model 9mm and have been shooting a lot of hot ammo in it, check the frame very carefully. If the frame is going to crack, I’ve seen it most commonly on the left side toward the front, right along the slide rails”.
On page 39 he mentions that the US Navy SEALS adopted the SIG after the Beretta 92s broke repeatedly.
In the book, “ Modern Beretta Firearms “, by Gangarosa, Gene,
He mentions the switch from Beretta 92s to the SIG. He also mentions the SEALS were using SIGs before they switched to M92s, as they were having from problems. He also mentioned that the SEALS were using 9mm +P+ ammunition in their pistols.
It would seem the SEALS went from SIG; to Beretta 92; to SIG; again and the problem is ammunition ?
In the old magazine articles after WW2 there used to be mention of damaging pistols by using submachine gun ammunition in them.
Beretta did fix the problem with the M92s.
It would seen that the Norinco NP22 would have the same problems as the SIG.
The Norinco NP22 is made with a steel frame and called the HP77B.
