I didn't read the whole thread, but here are my comments, after carrying 1911-types in a CBST several days a week for a few months, both tucked and untucked:
1. It is quite comfortable, tucked or not.
2. Tucking is easier than it is with most other tuckables.
3. The steel clips that come with it work, but will invite inquiry if exposed to the world and not covered by a concealing garment or bloused shirt. I replaced mine with the velcro-fitted V-clips, put velcro in the appropriate spots on the two belts I wear most, and I'm convinced that is the way to go. It becomes invisible to all but the most diligent "gun spotter" with this setup.
4. You still should use a good gunbelt to avoid sagging and discomfort.
5. You should have the "combat cut" to prevent snagging your fingertips and/or thumb on draws.
6. The only serious drawback in the design I've found yet is that is is hypersensitive to canting the gun on the draw. Unless you draw the gun straight out, opposite the direction it went in, it will hang up nearly solid. Any canting forward or backward on the draw causes this problem. Practice helps, and I don't know if non-1911 pistols are as susceptible, but it is an issue with 1911s.
7. I can comfortably conceal full-size 1911s under a tucked dress shirt with this design better than with any other I've tried, and I've tried several.
8. With a Detonics Combat Master, it may be the ultimate deep concealment of a full-power firearm.
