I like the 47D mags. In fact, I use them for more than just my 45. I run them in my .40 single stack gun i use for USPSA. Have been working great!
I just got three more from Santa…
I have 47D’s that have been great in my Colt and Kimber. They do not work in my TRP Operator ( dont lock the slide open when empty ). For the TRP I bought a bunch of Springfield mags with the loaded coupon, and they have been 100%.
Wilson’s are my favorite. I had my TRP magwell TAPERED so it would fit the 10 rounders.
Get the TRP OVER the Kimber- don’t go there.
Welcome to 1911.
I’ve also experienced the weak springs with the 47D’s, now its ETM’s & Tripp mags, both run great in my Wilson CQB,
I have the Wilson’s and CMC power mags. The CMC’s are the only mags that work in any 1911 I’ve put them in. The Wilson’s have been sent back and replaced and still choke a series I Kimber Compact I have.
I will only buy CMCs from now on.
I’m vote for the ETMs.
Any Wilson mag is great because they work and if for some reason they do not at any time during the life of the product you return it and they send you a new one free of charge.
That said, I used 47D mags for five years in my WC Professional Model. I had two of the seven need replacement in that time, which Wilson did free of charge.
Last year I switched to the ETM because they are about 3/16 inch longer, making a little more room for spring. In theory this alleviates spring issues 8 round magazines built in the same length case as 7 round mags have. I have had no issues out of my set of seven mags (through my Professional Model), but only have about 1500 through them to date.
I haven’t had a chance to run the CMC’s. I usually pick up a 47D when I see them on sale. Never had an issue with one, in fact they helped with feeding issues on a Kimber that I once owned. However, I don’t put nearly as many 1911 rounds down range as others on here.
CMC Powermags are my first choice, Wilson 47 are my other first choice.
The 7 round Wilson 47 is, IMO, the most reliable 1911 magazine out there. They’re G.I. mags afterall…
I have had great luck with 47Ds but agree with the others that the spring could be a little more robust.
I use Wilson ETMs and Wilson kits to update other mags with no complaints.
I use the CMC and ETM’s mainly myself. I have a few 47D’s laying around as well. I would like to try out the Tripp Cobra mags.
ETM’s.
There is no mag but CobraMag, and Tripp Research is its name.
I’ve had good luck with Wilson 47D mags, but what spring should be purchased for replacement? Just a factory rebuild kit or something from Tripp?
The 47Ds were unreliable for lockback and feeding in my TRP. CMC Powermags fixed this.
I understand why the W-R 47D was the standard for the longest time, but the ETM and Tripp magazines with the longer metal body designed for 8rd use are the better design - I’m down to a pair of each, and CMC Powermags that I rely on, the 47D’s are all training mags anymore.
I’ve had the best results reliabilty wise using the Wilson replacement springs and followers.

This seems to be a fairly common problem from what I’ve read.
