1911 slam- fire. Yes, this is a thing.

The tool marks were pretty evident on the sear and hammer hooks.

I would like to see a photo of the hammer if you could post one. Curious what kind of damage a dremel jockey can do to the hammer hooks to allow the hammer to drop past the "half cock" hooks and impact the firing pin.

There are no drop in parts on a 1911.

Did your friend reassemble the pistol and test it again? Curious minds want to know! Did it exhibit the same issue after assembly?

Yes, the hammer still drops sometimes when the slide is released. He will trash those parts, replace with the kit when it comes in, and test-fire. The down side is I won't get it back for 2 months because I'm leaving this week for a short overseas tour (where I will be carrying a Glock BTW). Anyhow, it will be ready when I get back.

Don't tell that to every armorer who served in the big military from 1911 until probably the early 90's, since that is how the STANDARD ISSUE service pistols were usually repaired (excluding the ones used by units like the AMU and other "special people").

Of course those were all Colt's.

Are there 30 companies making 1911's now? How many other folks just make parts? Do they are use the same blueprints?

They are supposed to be using the same blueprints, but many parts are now some sort of "match" or custom version. Any basic part should drop in - that was the intent of the pistol in the first place, regardless of what Kimber or Dan Wesson is doing.


This is a good reminder that most 1911s are clones. "1911" is a concept, not a model.

Of course, once people start producing things out of original spec, it becomes virtually essential to make everything out of spec. If you've got a square hole that needs filling, and some folks are making the hole .3"x.3", while others are making it .35"x.35" and some are doing .27"x.27", and they all have a manufacturing variance of .03", and you're selling rods to go in all of them, you basically have to make yours at almost .4"x.4" and count on people fitting (read: filing/grinding/cutting) them down to size. After all, you can't grow more steel.

Plus, you have all the different approaches to reduce clearances. I hate how many tighter fitted 1911s have their barrels lifted further into the slide, making the guns shoot low with standard sights. You can make the frame slots narrower, or the slide rails taller and both will have a different effect on where the barrel ends up.

But I do think that some basic locations and angles should be the same across the board, regardless of what's being done to fit the recoil parts.

What's funny is just how excellent the accuracy was with the original issue pre-war 1911 pistols, considering that they were all drop in parts.

If you have very, very good control over manufacturing tolerances (and/or have a high willingness to scrap parts that are just barely out of spec), then drop-in can be quite accurate. Heck, there are medical instruments and other devices where the drop-in replacement parts are orders of magnitude more accurately sized than anything in gun world.

Of course, that stuff doesn't cost $39.99 on sale at Brownell's, either.

More like picking parts out of a bin till you find one that fits. Also those pistols were quite loose in tolerances compared to a new CNC built 1911.

Even so called "drop in parts" sold commercially are all oversized and almost always need to be fitted.
