I don't have any photo of me wearing my handguns. I typically wear my smaller auto...a Glock 27 (I also have a Sig Sauer, SigPro 2340). The Glock 27 looks a tad larger than what you're looking at, but I'm sure thicker (due to the higher capacity magazine...staggered ammo). The reason I picked it was the amazing stopping power of the .40. I also found it as an accurate and easy to shoot gun. I was quite surprised by that. I'm not a great marksman, but that gun and I just "clicked."
I prefer to carry my Glock in a leather Galco holster just like the first image attached. The holster pivots the gun slightly forward and is designed to carry the gun at the waist, half the distance between one's side (directly under the armpit) and the tail bone (small of back). It tucks right behind the hip perfectly and comfortably. But because it is an outside-the-pants carry style, I use it less often. I'd like to get a Galco that carries the gun nearly horizontally at the small of my back (like the fourth image attached). I almost bought this model instead of what I have...both would be nice!
More frequently, I use a nylon Uncle Mike's (just like the second holster pictured) carried inside-the-pants near my tail bone. It's very easy to take on/off and does stay on the pants without accidentally coming off. There's a neat little "catch" on the the end of the clip to keep the clip from coming loose from between the pants and belt...it catches on the bottom of the belt, not letting the tip of the clip slip past the bottom of the belt...very secure!. I'd like to get a quality leather inside-the-pants Galco to replace this Uncle Mike's holster. I typically prefer leather and nicer accessories (for just about everything in life), but the Uncle Mike's does work very well.
For my SigPro 2340, I have a leather holster...paddle style (just like the third image attached). But due to the size of the gun, I don't carry it often, but it is a sweet gun/holster/carry setup!
As you can tell, I'm a huge Galco fan. Their leather
screams "quality," looks wonderful, is manufactured at the highest levels, and works perfectly! They're worth every penny..........unfortunately,
lots of pennies.
EDIT 1: After I wrote this post, I remembered I previously posted in a different thread photos I've taken of my guns/holsters.
Here's that post with the photos I took.
EDIT 2: You better check your work's policy on handguns in the workplace!!!!!!!! At most businesses, this is the easiest way to get fired and ushered off the premises by security (if they don't call the police to do so)...they are not going to care whether you have a permit to carry it. Most of those workplace policies include leaving your gun in your car (if the car is on their premises). A pocket knife can cause problems, too. If they are "gun friendly," you have the best job in the world!

Just a big FYI!
