Difference Between Wilson Combat 1911 Mags?

[HMMurdock]

I've had more 1911s than I've had women. And I've had a lot of women.

...and in that time I've found the most consistently reliable magazines have been those from Wilson Combat in any make/model I've had. However, I now see they have the standard magazines, the ETM and the Sentinel. I read their descriptions on their website and it all sounds the same to me. Does anyone know what the differences are? there is only a couple of dollar difference between each it seems and I just want to know how they are "different"?

The ETM has a slightly longer tube with wrap-around floorplate simulating a base pad so as to give a little more spring space. The 47D really crams things in and is often hard to seat under a closed slide. The only thing I know about a Sentinel is their short butt gun, with its own magazine.

So the ETM should prove more reliable than the standard in a full sized Kimber (no mag well)?
