Springfield Armory 10 rd. Mags

[5pins]

Has anyone used the Springfield Armory 10 rd. .45 ACP M1911 mag? A dealer around here has one for $25 and it looks good. What about the lack of a stop notch on the front of the mag?

Can't help with the Springfield mag, but I have a couple of 10 round Mec-Gars. I don't use them much, but they seem to work fine and they cost less than $25. I think they were around $16-$17.
