If I'm not mistaken the Speer Lawman TMJ has a truncated nose and a shorter over all length than standard FMJ. This may be the cause of your feeding issues. While you could probably have your barrel throated to accept it is it worth the trouble when there are good cartridges that don't cause issues in 1911's?
As to why you are seeing the issue on the last round it may be because the cartridge isn't supported by the round underneath it during feeding and changes it's feed angle a bit.

You might call Ed Brown and get their recommendations.

Try Wilson combat ETM mags. Zero malfunctions over 800+ rounds on my 1911

The OP apparently had issues with every magazine with the Speer Lawman TMJ but none with the FMJ. Additionally his new CMC Powermag is a top tier magazine equivalent to a Tripp or Wilson ETM.

Magazines are not the cause of every problem, or the solution. Often they're a Band-Aid to an underlying problem that if corrected would allow a wide variety of different magazines to be used without incident.

If I were you, I would call Ed Brown first.

Call Brown

Thanks redcliff. You may be right about the Speer Lawman TMJ having a truncated nose. (I am not certain, but the "T" in TMJ may mean "truncated."). To my naked eye, the Speer Lawman TMJ nose and length appears standard, but I presently do not have any other factory ammo with which to compare it. (I have some reloads from Freedom Munition, and they all appear similar in nose and length to the Speer Lawman TMJ, but there may be differences too subtle for my untrained eyes to detect).

In their manual, Ed Brown advises sticking with Federal and Winchester 230 gr. FMJ. In your experience, what is the most reliable ammo to feed a 1911? Or does it vary more from gun-to-gun?

I will call Ed Brown later. Thanks again for your advice.

It's actually total metal jacket. The entire bullet is jacketed, including the base so there's no exposed lead. I believe your problems are ammo and/or magazine related. I tested different factory ammo and magazines in all of my 1911s to find a common denominator that would run flawlessly in all of my guns so that I could standardize. I found that 230gr American Eagle fmj and Tripp 8-round Cobra mags were the most reliable. For reloading, I use either 230gr Rainer plated or Hornady fmj bullets.

Edited to add: For HD ammo, my Ed Brown SF runs best with 230gr Golden Sabers. Federal HST rounds have a wider mouth, which tend to get caught on the feed ramp.

it to early in the life of the pistol to worry. It is still in its breaking stage. Shoot a couple of hundred rounds more, I am confident all the kinks will be gone.

[redcliff]

Yes, Speer makes the Lawman TMJ in both flat nose/truncated versions in 3 weights including 230gr, as well as TMJ RN in 230gr. Its hard to tell the players without a scorecard.

Have you checked out this article? Were the malfunctions consistent in their nature? If the malfunctions were consistent, what would they be classified as in that article? Not an expert, merely curious.

[cindynles]

I essentially had three failures to feed, and one failure to eject. On the failures to feed, the gun did not go into battery; it was not a "double feed." On the failure to eject, the casing did not completely eject all the way.

Was the failure to feed like this?



Was the failure to eject like this?

[cindynles]

That particular failure to extract was caused by my extractor "clocking". It may or may not be causing your problems, but it is easy to check. You can check that by pushing on the top of the extractor and seeing if it rotates in the slide. This is what "clocking" looks like.

I recently bough a new Special Forces, Government-sized, with Gen III coating and an ambidextrous thumb safety. I love the chainlink treatment. This is my second 1911. I also have a Nighthawk Talon, and love it. I am something of a 'newbie" to 1911s, and have only been shooting them for about a year. I have had two range trips so far with the Ed Brown, and have had the following issues. (The pistol was cleaned and lubricated before each range trip).

1. I shot 200 rounds of factory Federal 230 gr. FMJ, without any issues.

2. I shot 300 rounds of factory Speer Lawman 230 gr. TMJ with the following issues:

With an almost new 8-round ACT magazine, I had one failure to feed, in the middle of the loading. (I used other 8-round ACT magazines, too, and they worked fine).

With a new 8-round Chip McCormick Power magazine, I had one failure to feed, and one failure to eject (both on the last round). (I used five other new CMCs and they worked fine).

With a new 7-round Ed Brown magazine, I had one failure to feed on the last round.

These issues occurred with three different kinds of magazines. It seems the problem could be the gun. On the other hand, the problems occurred with only one kind of ammo, the Speer Lawman TMJ.

Do you think this is a matter of the gun needing to break in a little more, or do you think it is more of a magazine and/or ammo issue? (Speer Lawman, I believe, is supposed to be good factory ammo). Has anyone had similar issues with their Ed Brown? (The gun is tight, but not like a Les Baer; it takes down fairly easy).

Thanks in advance for your advice.

I'd call Ed Brown and send it back in. None of my Browns have ever had issues feeding anything. They run TC all day long.

You could try another TC round, or maybe a different box of the speer. Sounds like feedramp could maybe use some work, but Ed Brown makes great guns and the tolerences from gun to gun are very consistent. Could be a bad batch of ammo I suppose. I'd probably send it in.

Both of my Browns needed somewhere around 500 rds of ammo thru them (maybe more?) before they fed flawlessly. That is not an indication of faulty craftsmanship but more the sign of such tight tolerances imho.

The ammo was 200g LSWC and mags were Wilson 47Ds.

I used one in USPSA for almost a year and it ran flawlessly. The SF is a safe queen and both are still my most accurate shooting 1911s.

I say keep running ammo thru it.
