My Favorite 10mm 1911 Pistol Magazines

I’ve had a number of 1911-style pistols over the years from Dan Wesson, Rock Island, and Taurus. Now, I have a 10mm 1911 TRP Operator with a 6″ barrel. The one thing I learned years ago is that you need quality magazines to help with reliable feeding. I word it this way because there are many different design elements that need to be executed correctly and the pistol to be adequately cleaned and lubricated — it’s not just the magazines that cause the 1911s to either work or have problems. With that said though, they are an important piece of the puzzle and going cheap isn’t something I would recommend.

Over the years, I’ve had two 10mm 1911 magazines recommended to me that both work great with my TRP Operator. One is the Wilson Combat 47NX and the other are the Tripp Research CobraMags and I’ve used both their 9- and 10-round models. Both brands of mags work great and I have no reservation recommending either.

I’ve shot a variety of Underwood HP and hard cast rounds as well as S&B 180gr FMJ out of my mags without any problem and have no had to do any tuning to the feedlips, etc. They just work.

These are two of the 9 round CobraMags loaded with Underwood 220gr hardcast 10mm rounds. Note the part number on the mag body. 9R-10mm-RG.
On the left are two Dan Wilson 9 round 47NX magazines and on the right are two 10 round CobraMags. By the way, they do sell a “tactical” 10 round magazines and the only difference is that they have a black finish to not reflect light – I actually reached out to Tripp Research and confirmed that.
Here is a pile of 9- and 10-round CobraMags. The 9 round mags have the red hard cast Underwood bullets showing and the 10-round ones are loaded with 200 grain XTP if I recall right. I have a few different XTP loads and they all feed fine.
From left to right: 10-round CobraMag, 9- round CobraMag, 9-round Wilson and a flush fitting 8 round Springfield magazine. All work just fine.
This is how far the 10-round CobraMag sticks out.
This a 9-round CobraMag
This is a 9-round Dan Wilson
This is one of the flush-fitting original 8-round magazines that comes with the TRP Operator.

So what do I recommend?

Honestly, I’ve had very good luck with all of them. I prefer the 9-round magazines from both Wilson Combat and Tripp Research. The 10-round magazines stick out quite a bit and I save them for the range, hunting or some other situation where length doesn’t matter.

I hope this helps you out!

Note, for Tripp Research Cobra Mags, I have bought them both direct as well as from Dawson Precision.


Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
