Same here, except I have a Speed Master for the K/L frame and Combat Master for the 1911 - not good for true comparison. Further, Iam not sure what the difference is between Galco's CM102(L frame) and CM112(K frame). My 2.5" 686 fits perfectly in the CM112, which is for my 2.5" 66.
The reason I asked is that I just snagged a new Galco SM134b on eBay for $39. I know the CM134b is for the 2.5" N frame and hoping it works will fit my 2.5" 627. From what little I can gather, the SM may ride a little higher than the CM.
