What I can find, shows the upper end of .445SM loads to be 42,000 CUP which is not in the class as the .500 S&W's 60,000 PSI MAP SAAMI rating. ETA: 42,000 CUP is about 46-47,000 PSI |

The .500s have been made this way since the first one. Originally Posted By backbencher:

Not .500" S&W, but can you recall a Dan Wesson letting go the same way? Since the frame itself broke where the barrel screws into it, I assume the difference in the barrel construction (1 or 2 piece) in front of that wouldn't make any difference... |

You mentioned that you use Armscor 1911s as well. I was wondering what your experience has been. Forgive me if you've answered this already.

This is an excellent thread, Ron.
Folks, his business is basically destruction testing firearms. Many manufacturers test some of their weapons to destruction, but almost nobody does it to this many different weapons. There's some valuable information here. As for the AA kits, mine is great...but it works best with Golden Bullet. And it needs to be cleaned every couple of thousand rounds to keep it running reliably due to carbon buildup. |

Destructive testing, but not abusive testing. Cleaned, maintained, lubricated, fed proper ammo. As opposed to testing that is deliberately abusive.

Quote HistoryOriginally Posted By HendersonDefense:
Here's what happened to our S&W 500 here on the range. It's been used on a daily basis for nine months with weekend use a bit higher. Davidson's (who we purchased it from) won't warranty or repair it because they "have determined that the damage to this weapon was not the result of a defect in the materials or workmanship of the firearm". They actually said... "We do not recommend firing this firearm as it is not in a safe condition to shoot". Not to poke fun at the blind but I'm pretty sure Stevie Wonder see that it's not safe to shoot 
We use Magtech ammo in this weapon and never had an issue with the lot as we shot plenty of ammo prior to this in our other S&W 500. We didn't feel the need to quarantine the ammo and the rest of the lot was used without issue. Since this happened, we are now going to put a six-month life span for all of our S&W as a preventative measure to avoid any possible injuries. Speaking of injuries, nobody was injured but the shooter was a bit shaken up just because of the weapon falling apart after the shot went off. He was a good sport about it and ended up shooting the other S&W 500 and we put him on a Desert Eagle .50AE and M134 minigun for free because of the scare. EDITED: Smith & Wesson sent the letter saying they won't repair it to Davidson's (who we purchased it from). http://i.imgur.com/XsCWuun.jpg http://i.imgur.com/dBaOKDd.jpg http://i.imgur.com/renO0Gf.jpg http://i.imgur.com/80W4pWn.jpg http://i.imgur.com/OeeiKHS.jpg I can understand them saying they won't repair it (that thing is totaled), but I'm curious how they came to the conclusion that the failure was not the result of a defect. Did you send it in, or just send them photos? |

I am curious if and for what are you using a sonic cleaner? I know that you cannot use a sonic cleaner on anything aluminum as you will see cracks quickly. I am not a scientist, but curious if sonic cleaning, on a regular basis, would have any long term effects on the steel as well.

We heard the same thing about not using a sonic cleaner with aluminum parts. We consulted with somebody who has more knowledge about this and we were told that we just need to monitor the pH scale of the solution. We were also told that the parts that we are cleaning and the cleaner (Simple Green) we are using are something that will never affect what we are doing. We've been doing this for over two years and we have yet to have an issue of parts failing or cracking. As for the sonic cleaner, it's a commercial unit that we ordered from a firearms distributor. I will get the name when I get to the shop this afternoon. V/R Ron |

I want to give a brief update on some pistols that have been taken off the line.
We've had four more Glocks go down within the last five weeks and they all experienced the same crack on the right rear portion of the slide. One slide cracked yesterday and just by chance, a new recoil spring was installed Tuesday. Somebody asked about the S&W 500 catastrophic failure. To answer your question, we did send the complete firearm back to the factory. The Armscor 1911's are just as reliable as any of the other 1911's we use. We have (I apologize for not knowing the models) the Springfield 1911's with fancy wood grips and sights but they run just the same as the Armscor models. The Sig 1911 has yet to suffer any type of failure. V/R Ron |

V/R Ron 1911s don't have trigger springs. Sear spring maybe? There's a leaf spring that it presses against, so technically it does. Yes, technically it's a tigger, sear, and grip safety spring. I have many, many thousands of rounds through 1911s with CMC Power Mags. The only part I've ever broken is a hammer strut. I've broken two. My M9s have seen similar use. I've yet to have a part failure. With enough use, anything will break. I say the decocker on an M9 break once. I've also seen a bushing break on a 1911. This sucks because the recoil assembly winds up down range. |

I'd be willing to bet a little $ that the Gen4s will if they change the recoil springs on schedule (which I'd imagine they do). But, it'll only matter for folks like Henderson as us mortals will never hit that round count in the time period they do. Good data point nonetheless though. |

Any idea on the rough round count of various platforms before they tend to go down?
Something like: Beretta 92 - 10k rounds Glock 17 - 20k rounds 1911 45 - 7.5k rounds Sig P226 - 15k rounds etc. Also, what are your most common 1911 failures / broken parts? I'm guessing extractors, but I'd love to know what to stock up on. |

V/R Ron Sounds consistent with what Glock says about the Gen 4, although they just refer to the RSA. However, maybe it is the weakening of the RSA over time that causes the cracked slide, therefore the Gen 4 RSA possibly increases the time to failure. Just a thought. |

Also, I don't consider the weapon malfunctioning from being filled with carbon a failure. I consider broken trigger springs, recoil springs, slides, barrel locks, etc failures. The armorers clean the pistols at LEAST once a week if not more. The weapons get lubed every day, twice a day. It's when they are lubing them that armorers will make the determination if the weapon has to be taken off the line for immediate maintenance. V/R Ron |

Again, I have to go through all the Glocks when I get a chance. The other area where they crack is the thin area at the ejection port. This will NOT cause the weapon to stop working. It only causes the bullets to fly high and to the right.

One of the more common areas I hear of high round count Glock slides cracking is right below the ejection port, but that doesn't sound like what you're describing. What's your maintenance interval for replacing the recoil springs on the Glocks? Are these all 9mm? And I'm also curious of total round count at time of failure. Thanks I asked my armorers again and I want to be 100% certain but I THINK that all the cracks in the slide are exactly at this point and only on the Gen 3's. Again, I have to go through all the Glocks when I get a chance. The other area where they crack is the thin area at the ejection port. This will NOT cause the weapon to stop working. It only causes the bullets to fly high and to the right. http://i.imgur.com/EVIvVkv.jpg Interesting, thanks. I wouldn't have expected the slide to crack there. |

That location appears to be where the rear frame rail sits when gun is in battery. When fired and returning to battery under force that single location (on both rides of the slide) will bear the full force of the rear mass of the slide's UPWARD movement since the fulcrum/pivot point would be the front frame rails? |

Ron,
I work on the Dillon M134/Mk44 Mod 3s down range. Any issues with your gun? What firing sequence are you teaching on the trigger? 2-5 sec burst (100-250 rd) so not to damage the clutch? Any parts breakage issue, feeder delinker issues? Typical range day for us is 6,000-12,000 rds per day/gun. Failures are generally operator induced. What cyclic rate is yours set for? On the M249 SAW, I did with only limited amount of full auto using PMags in the magazine slot worked 100%. At dusk in the desert

So now that the S&W .500 is toast, what are you going to do with it?

Great post OP.
Have you seen any high round count CZs, and if so, how well did they do? |

Any comments of the durability of aluminum alloy frames vs. steel? Does the aluminum hold up?

On the M249 SAW, I did with only limited amount of full auto using PMags in the magazine slot worked 100%. At dusk in the desert http://www.hunt101.com/data/500/medium/zeus_rz.jpg CD We have four M134's in our inventory. Two are original GE's and two are Garwood G's models. The Garwood's have the latest updated feeder delinker that the 160th SOAR (was able to review their findings and recommendations) found to be better than all others tested. They also have the clutches that reduce the chance of stoppage from the operator. Garwood still has sixteen years left on his patented design but the last time we spoke he didn't have any available. He visited Battlefield Vegas several months ago and demonstrated the difference between his design and the hand-off as compared to the others. Our GE's are the old-shool units that still utilize the bolts with the tails, no clutch and still outfitted with spade grips. One of our GE's is modified to use German DAG blue ammo. It took us a LONG time to figure it out after several other individuals told us that it wouldn't work. It took time and patience to mod all the areas in order to get the blue ammo to function properly. We normally do 1.2 second burst because we sell it in belts of 100 rounds. We've gone as long as 1,200 round bursts for customers that want to go all out. I am SO exhausted right now that I can't do the math but those numbers will give you an approximate cyclic rate. Our GE gets run everyday of the year.. sometimes just a few hundred rounds and some days several thousand but those are usually Friday's and Saturday's. V/R Ron |
