I have literally bought over 250 holsters for my handguns over the last 25 years. Lots of trial and error. I have several draws full of holsters that I have never used. And I have sold many of them. Just never get around to it.
I have learned enough lessons and finally settled on a holster maker and a particular holster he makes that works for me. No more guessing, no more 4 or 5 holsters until I find the right one. No more kydex. I have dozens and dozens of never used kydex holsters that have cost between $25 to $150. Actually, I do use Kydex holsters for my OWB Tactical Rigs when I train and shoot steel. But the holsters I use for daily carry are always IWB. I have found one model holster that just works for all my carry guns. Each time I buy a new gun that I know I will carry, I just order one up.
It is the Tucker Gun Leather "Cover-UP Plus". The "Plus" is that the mouth of the holster is reinforced to stay open to make re-holstering a snap! Every Cover-Up I have is so freaking comfortable. I don't like Kydex IWB because it is uncomfortable. Leather is skin right? Well it makes sense that skin on skin is more comfortable than skin on plastic. Especially when the skin in question is my skin!
Here is my latest Cover Up Plus from Tucker Gun Leather. I just ordered one for my new Colt Commander LightWeight in 9mm. What a joy it is to carry in this holster! This is my first 1911 carry gun and I love it! I have an all Steel Colt 9mm Commander and a 9mm Colt Competition 70 Series coming tomorrow as well. I am even thinking of having Tucker make me a Cover Up Plus Holster for the Gov't sized Colt Competition I have coming.
The feature I absolutely love about the Cover Up Plus is the adjustability it offers. It is simple to adjust for cant and height, as you can see be the J-Hook in the picture below. Lots of holsters are either NOT adjustable at all or only adjustable for either cant or height. The Cover Up offers adjustments for both so you can find the perfect fit. Let's face it, we a NOT all the same size and shape, and there is NO WAY one holster will fit everyone.
If you are looking for an awesome IWB holster, try a Tucker Gun Leather Cover Up Plus! It has a full sweat-guard on the other side that you can't see in the picture. It is also not bulky and not much thicker than a kydex holster, so it doesn't add a belt size! It also will not activate or deactivate the thumb safety on your 1911.
Updated with a pic of the other side. FYI I ordered it "Roughout", meaning the rough side of the leather is on the outside and the smooth side is inside. I don't care what people say, Kydex is much harsher on the finish on your guns. Some guns I don't care much about the finish, like my Glocks, or other polymer pistols. But the finish on my Colt is a beautiful polished blue. Sure leather will wear the finish, but not as harshly as Kydex.
