I'm issued a Safariland ALS, and it's a fine holster as everyone has said. However, that being said, I VASTLY prefer the two SERPA holsters I have (a "concealed carry" level 2--that's in quotes because unless you're wearing a really baggy sweatshirt or jacket, it's obvious to anyone with eyes-- and a level 3 duty holster) for several reasons. I love that you can change the belt attachment from low ride to mid ride in about a minute, add spacers, and adjust the cant of the holster to about six different angles; the draw is so incredibly natural that you don't even think about it when you draw, which I have to do when I draw from my Safariland (though that could be because I'm new to it; though, it took me a grand total of three draws from my level 3 SERPA to feel like I'd been using it my whole life), and yet, having tested it with fellow officers and friends who are not officers, not one person could get it out within thirty seconds WITHOUT ME FIGHTING THEM unless they were literally right behind me; and lastly, I love that the hood CANNOT close without human manipulation, meaning that if you want it open, it STAYS open, my biggest complaint about the Safariland and other hooded holsters, where the hood can close on you without you wanting it to.
But, I do believe that you need to mix comfort and security, and while the security is the same no matter who is using it, not everyone will be comfortable with the system. Before moving to a whole new system (unless required by department policy) I'd suggest finding someone who owns one and getting in some practice reps. I've found with every holster I've used I can tell just how comfortable I'll end up with it within the first couple dozen draws.
