Howdy again,
With both Smiths and every other brand of pistol I have carried, I either use (1) factory mags (often made for the factory by Mec-Gar) or (2) Mec-Gar magazines.
While I know some folks have had problems with M-G mags, personally in my experience, I have never had an issue with a single of their mags. I normally use their +2 mag offerings, for example their P226 9mm 17 rd magazine, in nickel finish, to readily tell it at a glance from my factory 15 rd mags. I do the same thing with HP mags and other brands when I have that option.
Where many of the other brands are concerned, I have consistently seen them be nothing but a major problem for folks during qual courses. It became enough of an issue that the last two agencies I worked for said factory only magazines for duty use/quals. The weapons we issued, except for Glock, had factory mags made by M-G.
It is not my intent, nor that of any other member I believe, to try to "trash" certain brands of mags. Rather we are just trying to share our personal experiences with various brands.
Hope this helps a bit. I think the mags CTD listed were shown as being Smith factory mags. I have no idea who makes their mags now. But if they are marked "Italy" they are M-G mags with the Smith brand name added - just as M-G does for Sig, Beretta, and many others.
