1911 double tapping?

Heavy ammo could cause inertia feeding, which would explain how a round could get into the chamber ahead of an extended firing pin.
The barrel/slide can't lock-up on an extended pin, the extractor can't grab the case rim if there's an extended pin, an extended pin would prevent the case from contacting the ejector, but, never say never.

The Thompson SMG had a fixed firing pin extending from the front of the bolt, and it worked, but it worked on a very different operating principle from the 1911.

Disclaimer: I do not own a Thompson and have only shot one once.

I know the 'grease gun' M3 just has a fixed nub on the front of the bolt that acts as the firing pin but I thought the Thompson had a moveable firing pin.
 
Tallball speaks the truth. Some had fixed firing pins and some had moveable firing pins.

The main difference between the M1 and M1A1 [Thompson] was the bolt. The M1 bolt had a floating firing pin and hammer, the bolt of the M1A1 had the firing pin machined to the face of the bolt, eliminating unnecessary parts.

Thanks for the prod to go look something up rather than just to rely on memory.
 
I could have been more specific, as in, "late, military Thompson's had . . .", but it wasn't really relevant to the discussion.
 
Dan Wessons use tool steel parts for the internals and this is essentially a new gun, so wear is not the issue.

If there is any thought in your mind whether this was caused by a mechanical malfunction, I will again say to call Dan Wesson immediately and have them look at it.
 
Thanks for all the replies. I am beginning to question if it was operator error after all-bump Fire-(never say never right....:)) Like said- it's practically new and of good quality. I've shot a few mags with no issues so I'll play with it some more. I've got my own range and shoot alone so the only threat is a few holes high on my target.:D
 
1. Ensure empty.
2. Hold trigger rearward.
3. Rack slide three times.

Does the hammer fall?

If yes, firearm is unsafe and needs the attention of a gunsmith.
