On the downside, they were expensive to pile up, and a lot of them just plain don't work as well as you had hoped. On the upside, you get a lot of experience with different brands and types of holsters. Sooner or later, you find that you gravitate towards a certain brand...their holsters just seem to work better for you than anything else. What's your favorite holster brand? For me, Galco seems to work out the best. Their stuff is universally well made, and their designs are well-thought out (or good copies of other well thought-out designs.) Disclaimer: the poll tags are just for fun. I own, or have owned, holsters from each of the manufacturers on the list, and they're all well worth the money. Except that Plavitz Custom.
