My unit has broke several in training, and although we got them fixed it makes me kinda nervous. We asked for spares to carry downrange and got told no. It's only approved for a bn level armorer.
So where can i order some from? |

Brownells also carries the Beretta parts.
Make sure you replace your locking block with the same series. If it is the newer locking block, it has a smaller slot cut into the rear face and it also takes a square shaped pin. You can not mix the newer block (square, small slot) with the older (round) barrel pin. Swap out the plunger pin, plunger and locking block. Breaking locking blocks can be caused by tired recoil guide springs. The force of the pistol slide going to the rear is not slowed enough with the tired spring. Throw a new guide spring into the pistol. |

Maybe we got bad springs? |

Factory new spring and locking blocks replaced into the pistol....and they cracked a block after 100 rounds,,,,,,,,wow. Pistol that has broken a few locking blocks may be showing wear that may put it into the end of its service life.
Slide needs a close look. Check for slide cracking. The pistol will still fire with a cracked slide, until it breaks. It may be time to have a close look at those barrels and frames. Inner portion of the slide, where the locking block "ears" pivot into lock-up, the rail cutout might be rounded/beaten back too far and not allowing the barrel to be locked into place when firing. The barrel may have had a change in headspace (rare).......

Checked them out today. I compared the recesses for the locking lugs with the slide from my often carried/seldom used police trade in.
They looked good. No cracks. The armorer refused to swap the recoil springs out, so I think I'm going to get a few of those too. |

When are they going to get it into their heads that buying lowest bidder crap magazines and being stingy on springs etc will cost service members their lives??? [/rant] More on topic, you should consider buying a couple of beretta factory mags too. The military is notorious for purchasing crappy mags, and bad mags are a serious weak point for the M-9. Best of luck to you down range! |

Here are some useful links that I have shamelessly copied from other threads.
Locking block Locking block (Brownells) Locking block plunger plunger As far as recoil springs, a new factory spec one is what I would try first, since it provides the best feeding. Factory recoil spring If your sure you want a heavier spring because your shooting more stout ammo... Wolff performance pack spring kit If you have a 92FS, I would suggest taking a look at the 15lb spring and a BufferTechnologies guide rod and buffer. It does reduce the pounding that the slide takes as well as reducing felt recoil a bit. These do NOT work well in the 92F for some reason. Recoil buffer Honestly, a new factory 13lb spring along with the buffer tech setup is what I have in my police trade in 92FS along with the newer style locking block and plunger. As far as mags, CDNN has the best deal these days on MDS mags. (15rd) They also sell "slick" surface factory 15rd mags for around $20. |
| Instead of trying to look for slide cracks, use the test that Beretta uses in their Armorers schools (civilian). Hold the slide suspended from muzzle end on uyour pinky finger and tap it with the barrel. It should ring like a piece of fine crystal. If you get a 'thunk'...the slide IS cracked, even if the crack is damned near impossible to see. |

Best of luck to you down range! We took up a collection and bought a bunch of the good mags before the last rotation. You are right about that though. Even before we bought a bunch I ran my personal ones. |

| Just FYI, three of the parts listed by norseman1 can be purchased in one fell swoop directly from Beretta USA. Their "locking block kit" comes with a new locking block, plunger, plunger roll pin, and recoil spring. The kit costs about $60. David Olhasso also sells the locking blocks for $60, but it's not the whole kit like the one Beretta USA offers. |
