I’m a big guy with a bad back. I’ve got a closet full of holsters I’ve tried and failed, along with belts that have also been disappointments. After a lot of money spent through the years I finally found two gems that work great. The first is “The Bull Belt” by Hank’s. It came with 2 heavy duty buckles, one silver and the other brass colored. It is one tough belt. Made in the USA. At 1 1/2 wide x 1/4 inch thick it is truly a Bull. It shows no wear even after three years. It holds my holster securely and as an added bonus doubles as a back support. At $60 a pop, it is well worth the money. I even bought a second one. With a 100 year guarantee you can’t lose.
As for a holster, I took a chance on Alien Gear. I avoided it because I thought the name was funny, but I was running out of choices. I purchased their Cloak Tuck holster IWB for a Smith 9mm. After an hour of wearing it I forgot it was even there, so I then purchased another IWB for a larger 9mm Ruger which was a little better because it was a newer 3.0 version. I just bought a small revolver and ordered a new Alien Gear holster for that one too.
It was a long expensive road, but I’m glad I found these two. I’m a Hank’s and Alien Gear customer for life.
I hope this helps those who are searching for belts and holster like I was.
God bless America and the USCCA
I can second Alien Gear for a big guy. I have the cloak tuck 2.0, wish i had gone with newer, but i still love it! I went with a Bigfoot Gun Belt though, about the same dimensions, slightly less leather with a spring steel core. I loved it so much i ordered one sized to wear without my firearm for when I’m at work wearing my duty belt.
As an aside, if you have a pistol with extremely rough grips, N82 Tactical (Nate Squared FYI) offers a very nice holster with full leather backing that extends the full length of your pistols grip. Yes it’s a little bulky, I am aware of it, but it is comfortable and it keeps the rough grips of my pistol off of my skin.
Yet another big guy here. I also use Alien Gear holsters. I have a couple of their IWB 3.5 models, and they are very comfortable. Alien Gear is my holster brand of choice.
I also like alien gear. You have a lot of options. Mike…I know what you mean, I am a big guy also. I found that RAW DAWG has an excellent IWB. I can even wear mine with running pant/sweats. I make sure they always have the heavy tie, to support the the extra weight. But even up against the skin, this is a very nice comfortable option. Only about $50ish and lifetime guarantee. 
Alien holsters are great. I own 4 different ones. As for the belt have you tried Bigfoot gun belts.
Have not. I have a couple of tactical belts in black and brown, for all occasions!! 
My wife wants a magnetic holster from https://jm4tactical.com but not sure if they are worth it and if they are actually safe where she won’t have to worry about the holster coming loose or something happening.
I use the Jm4 and have found a few flaws along the way. Don’t get me wrong I really like this holster and it stays where I put it. They now make a high rise holster that is easier to draw from but I believe it requires the use of a belt. The one I have sits very low, almost pants height and keeps my gun very concealed. I have a S&W 2.0 compact 9mm. The one issue I have noticed is I have had to train to grab it from the holster without a full grip. My thumb does not reach the back of the gun all the way when drawing that low. That said I am able to have a full grip prior to it being all the way out of the holster. The other part I have noticed is that the grip rubs my skin throughout the day. a side draw while sitting means leaning forward a little more but still reasonable.
The positive is the gun never leaves my side, it’s never fallen out or even came loose. I love the fact that when I remove my holster at the end of the day it sticks right inside my safe. The trigger is fully covered like many of today’s holster. It’s also extremely comfortable compared to others I have tried. I usually forget it’s there. If I use it in appendix then I can reach all the way around it when I draw, but 3-4 o’clock took practice.
Keep in mind I am 47, disabled and over weight so a slimmer person with more mobility would be able to do things naturally that I have to train for.
I am trying a new belt from a guy on another gun forum. Double stitched leather, so far it is working great. I have gone through a LOT of belts.
