You have a few other options as well when purchasing your Supertuck, such as leather type and the "Combat Cut". The Combat Cut reduces the size of the leather paddle around the grip of your handgun and allows you to get a more firm and full grip when drawing. I recommend this option from personal experience. My first Supertuck did not have this option and I wound up cutting it myself. I opted to have this feature on my next Supertuck and couldn't be happier. It looks much cleaner than my homemade Combat Cut and is just as effective.

The Supertuck is advertised as being a "tuckable" IWB holster, meaning that, due to the design of the attachment methods, you can tuck your shirt into your pants and over your firearm while carrying IWB. I have never been able to make this work, though without blousing my shirt out to the extent that I looked like a total fruitcake. I think I tried that once the first week that I carried with the holster and didn't make it out of the house before I untucked my shirt. Sorry. If that is your primary attraction to the Supertuck then it may not be the holster for you. For me, however, the adjustable ride height, adjustable cant, and the way the leather paddle conforms to my body while the kydex securely retains my firearm are the attractions. The fact that the belt attachments are so far apart also makes for a very stable ride and keeps the holster from rocking forward or aft.
Using my first Supertuck, I was able to easily conceal a full-sized 1911 in summer attire. When I switched from 1911's to Glocks I tried another holster, but I couldn't make the ride height work. I ended up selling that holster and purchasing my second Supertuck which I still use.
Another useful feature of this holster is its ability to hold different length firearms as long as their frames are similar. For instance, I can conceal my wife's sub-compact Glock 26 or my full-sized Glock 17 in the same holster. For you 1911 aficianados, you can conceal your Officers' Model or Defender in the same holster as your Government Model.
This is an extremely versatile, comfortable, and concealable holster. I have been using them regularly for over 2 years and have had no issues whatsoever. Just to give you an idea, I work on a military base, so while I can't CC at, to, or from work, I do CC any other time I leave my house. Ok, enough of me talking. I'll post some photos now.
