I'm considering the Tanker because I've found it works better than a belt holster when carrying a backpack. I also like the greater protection from rain and snow when carrying one under a jacket or vest. I've got them for revolvers, but have never carried a 1911 in one.
All good reasons. Years ago I used to carry a Smith Model 39 in a tanker under all of those conditions, and I liked it, a lot. Since there's not that much difference between a 39 and a 1911, I suspect it'll work just fine.
