There are a lot of holsters out there but it pays to do research or walk into a store and hold it in your hands before you buy. I have seen people buy $90 holsters online and find them uncomfortable or they find the clothing they are wearing doesn’t work for the holster they purchased. Things to think about when choosing a holster are the depth the gun will sit in it, usually a holster like the Galco Kingtuk will have some adjustability, but also knowing how much the gun might sit off your body is another. Not all paddle holsters are the same in these regards and some sit lower than others. Recently we had some customer stop in our store that were doing IDPA but had no idea if the vests they were buying would cover the gun. It really isn’t just the clothing, it can also be the holster design.
I think OWB is a better way to conceal carry but that’s your decision, it usually more comfortable and easier to access. Some of the Blade Tech Holsters that are IWB are very sturdy and I would attribute that to the double loop design, sometimes that one clip holster design doesn’t cut it and can cause the gun to cant and not be where you want it if you needed it. Expect to see lots of Glock gun holsters, Sig Sauer holsters for Inside the Waistband, Outside the Waistband and The Blade Tech Evolution holsters.
