The answer to this is yes, depending on what kind of environment you expect to be in.   They aren’t hard, but they will hold up better than leather in many situations.   I find the holsters to be difficult to put on and off because of the clip on belts but they are very secure and I actually find them to be very useful for secondary weapons holsters.   Many nylon hip holsters also use valuable space and usually have room for a pistol magazine just in front of where the pistol holster.  There are hip holsters with and without, but I’d recommend the tactical ones.

I find the nylon tactical holsters magazine holder may not be the best placement for you because if you are right handed and your holster is on your right side, you’ll have to reach across with your left hand which may be awkward, but it’s an easy place to keep a spare magazine just incase you ever need one without having to carry an extra pistol magazine holder.  Uncle Mike’s holsters are not expensive and they won’t make you look rich, but I see plenty of made in China nylon holsters that I can’t tell a darn difference between them and what Uncle Mike’s holsters.   What kind of gun fight would you get in if you are carrying a carbine and need to use a handgun and still need spare mags?  Answer, a really bad one, just try not to get in one.
