When buying after market stuff like mags, for a CM .45 should I be looking for Officers model parts? As in will a mag for an officers model fit in a CM? I just bought a CM from my brother, and was looking thru the Chip McCormick catalog for some items to spruce it up.

Original parts seem pricey, and the new detonics is pretty pricey also compared to other 1911 parts.

Thanks
