So, I am shooting today my 1911 Sig XO. PMC factory reloads. And suddenly that:
D4R_5988_2610.jpg


Recoil spring is kind weak in this gun I was thinking to put something stronger just today. It looks like that is fired out of battery? Or ammo?
 
looks like a out of battery fire

does the SIG 1911 have a firing pin safety?

It should. From SIG site:

For safety the 1911 XO features a beavertail grip safety with speed bump, extended thumb safety, firing pin safety and hammer intercept notch and ships in a plastic gun case with cable lock.
 
Glad to know you are OK and able to relate the incident. A mutual friend of ours witnessed your surprise.

So, is it PMC factory ammo or reloads? In battery or not, if you're getting a face full of brass; take it to a gunsmith and get it checked out.

Thanks. Those are PMC reloads
 
Case head failure, not OOB. It failed at the unsupported section of the chamber.

Watched a guy try to blow up his Glock with over-charged reloads one day. Looks just like that. (Hilarious for me to watch, not so much for him to experience).

What does the gun look like?
 
Should be very careful to inspect the case before shooting if you use reloads , either factory reload or own reloadings , usually for full loads 45 acp and 40 S&W , I use cases less than four times using , avoid aluminum cases . the older used caseonly for reduces load ,minor power factor . For super charge , I only use 1 time using cases , please throw away any brass more than 7 times using .
 
Who cares about the case. Did you hit the target with that shot??

Any damage to the gun or your hand?

CS45

Hehe. I did hit the target. My face took a nasty gunpowder blast, I had my eyes on. Gun is fine.

Here what i'e came across on another forum, similar case:
The 1911 has a disconnector that should prevent an out of battery round from firing. If the gun is faulty and the disconnector is not doing its job then this could be the result. More likely it was an overcharged round and as the round starts to unlock the barrel and gets a little extracted the unsupported portion of the case blows out due to the high chamber pressure. The case it stuck hard in the chamber and the slide/extractor cannot pull the case out of the chamber so it will be partially unlocked and the gasses will blow down the magazine well, usually taking out the magazine or blowing the bottom out of it.

Edited to add......if the prior cases were bulged then his loads were probably on the hot side....maybe too hot. The web of the case that blew out may have been a little weaker than the other cases and gave out. Play with the high end loads and this can happen.


Now, those factory reloaded rounds are damn hot! They felt hotter than my own loads that were near max loads. Maybe, that was the case.
 
Is there a test to check if disconnector works properly?

Yup "gun 110% unloaded for this"

Rack the slide
Pull the trigger and hold "should fire"
with the trigger held, rack the slide again "hammer should stay to the rear"
Release trigger and fire "hammer should fall"

next

#### you gun and push the slide back 1/2" and try to fire "it should not"
 
With an EMPTY/UNLOADED gun, pull the slide to the rear, and bring it back until it is almost closed, pull trigger.
If nothing happens, your disconnector is fine. If it goes click without the slide being fully closed, there is an issue.

Bah, Dsiwy beat me to it ;)
