Why go 7 + 1 when you can go 8 + 1 - Colt Magazine GOV/GC/CC 45AP B 7 Round

This mag seems OK for my Colt 1911 Gov't Model (takes 7 rounds, loads manually, and easily ejects), but I haven't range tested it yet. However, I also ordered a less costly Mec-Gar 1911 .45 ACP 8rd Magazine from another vendor, which similarly appeared OK, but held an extra round while essentially appearing just like the 7 round mag (with about 1/16" more length), and having a non-tilting non-metallic bottom plate which prevents accidental scratching), so from here on out I'm going with Mec-Gar's (which I understands actually makes most OEM mags for many of the major gun manufacturers) 8 round mag (unless range testing leads to a different conclusion). Purists would prefer this, Colt's OEM version, which is fine with me, but I prefer the Mec-Gar 8 which has a lot more to offer for a lower cost.
