Yes, there is a difference between Gaclo, Don Hume and Desantis
When we got the Galco and Desantis holster catalogs we were pretty overwhelmed by how much stuff they had in there and it was really hard to figure out what we should start bringing in. First, I can’t say that one is better than the other because each has certain products that are tried and tested and look at function well. The Miami Classic shoulder holster is still very popular with Law Enforcment because it has that “look” that some professionals want. Most major companies like Galco, Don Hume and Desantis have very consistent quality products and we never get complaints about fit unless it’s a novice gun owner that doesn’t know they need a break in period.
There are many differences in hand sizing and not every ones fingers are going to reach. There are tuckable Desantis Holsters that have caught on with many white color concealed carry holders. Not all pocket holsters are the same and each holster may have an edge functioning with you with a certain type of firearm. I’ve got Don Hume Jit holsters for many of my medium frame guns but it didn’t work quite so well with my Glock 19. It was something about the balance and the depth of the holster but for my Sig 239 and my Smith & Wesson 38 Special, it’s actually my favorite firearm holster for the majority of my guns. You probable won’t know until you tried them though.
