The 7 round magazine is very reliable because the 1911 magazine causes the top round to nose down as more rounds are added to the stack. A 10 rd can have lower feed reliability in some guns with short or shallow feedramps because of that. The 7rd has also has long follower legs that track well in the tube.
In the old days, alloy guns were frowned upon mostly because Colt lightweights were prone to cracking at the dustcover. Why? They were too thin mostly.
Newer guns are beefier in certain areas that used to regularly crack on a Colt. When they crack they still work.
Jody didn't like alloy because he said while he could guarantee a steel five inch to run, the alloy was more iffy as to reliability.
Is there a seven round ETM mag, and if not, can you get much of the benefit of a seven round mag by only loading seven cartridges in an eight round mag?

Bill, please disregard my question re: magazines. I found your answer here: https://pistol-forum.com/showthread....houghts/page20
I shoot the 1911 platform better than any other. However I don't like the weight for all day carry, and I just don't see many people who use the 1911 for living carry the LW versions. Maybe this is a misperception, but it's a clue for me. I mean that in the most respectful way.
I have a lot of luck with alloy Commander-length guns. I run 8 round Wilsons in practice and carry 7 round Wilsons. I don't shoot as much as most and I don't shoot these guns all the time -- it's more fun to practice with 9mms -- so take it for what it's worth,

Full size ETM's are are not available as 7 rounders. The reason the ETM is Wilson's top 8 rounder is the tube is longer than the 47 series, that uses the same tube length for both the 47 (7 rounder) and 47D (8 rounder). The ETM was designed from the ground up as an 8 rounder.
In my opinion, you get a better spring and follower in the 47 over the 47D. You could put 7 rounds in a 47D, but then you'd still have the lesser follower and spring. If you have a bunch of 47D's, I'm pretty sure you could put replacement 47 spring and follower kits in them to get a 7 round mag if that's what you wanted to do.
