I had the same problem until I made a simple decision to add Hawaiian/camp shirts to my wardrobe. I bought a good, thick gunbelt and IWB holster and, voila, my goverment model 1911 disappeared.
If it's too hot for a camp shirt/T-shirt combo, I can still conceal under an untucked XL tee using an hankie as a sweatguard between me and my gunleather.
A convert !.........:o)
Ive considered full wardrobe chnges, Im just too hardheaded a redneck at this time, besides, as this thread illustrates, there will most likely be several different arms, modes of carry, events/situations etc per week/year to consider anything as one size fits all...
I plan to keep 'tryin on' different combos and whichever works best will be the 'right' one on any given day...
thanks for he thoughts...
