    Antero Staccato Mag holders

    Posted by Robert Eng on 5th Apr 2024

    This was the only mag holder I found for the Staccato magazines. It holds the magazines real well and I can get them out real fast. I recommend them for Staccato.

    Antero MRD Double Mag Carrier for Staccato P

    Great Product! Best Carrier I've used on duty so far. The adjustability and retention is the best I've seen yet. I hope they make a triple mag version of the same carrier, and I will buy that one too!

    Antero MRD double mag

    Posted by James on 28th Sep 2022

    This is the second double mag I've ordered from Long Shadow. I'm a Deputy Sheriff in FL and have used this mag pouch for two years in a variety of conditions and it has never failed me. Strong retention but fast when you need a reload. Blows my Safariland pouch out of the water. With this pouch you can adjust the retention on both mags which is not possible with my issued Safariland pouch which leaves a mag looser then the other. I prefer the traditional sideways orientation of the magazines over the forward facing, you cant go wrong with this pouch. Longshadow also offers basket weave finish which looks great if your department requires it.

    MRD double mag carrier basketweave

    Posted by James on 30th Sep 2021

    I’m a deputy in FL, was running the Safariland slimline forward facing mag pouch. Never really liked the forward facing mags as I’m used to the standard orientation I’ve been reloading from for years. Also the retention on the Safariland is not the greatest with one mag often being looser than the other. I’ve been running this mag carrier from LS Holsters for about a month now and it’s top notch, finally found what I was looking for and also the basketweave texture is some of the best I’ve seen for kydex, good if your department requires it.

    Wear this mag carrier on a duty rig, it’s durable, looks great and it does its job. Long Shadow is a great company to work with!

    Long's Shadow Holster was recommended to me by my firearms instructor who has a long history of military and law enforcement experience with a lot of different products. Before now, I had only carried a magazine pouch when issued one by an armorer, and would get whatever junk was at the top of the bin. I checked out a few other shops first to see if the price and selection were right, and Long's Shadow was dead on. Most of the places I looked didn't have anything on the shelf, and certainly couldn't speak intelligently about what I needed. I went into the shop and was presented with my options and a wise recommendation. I upped the game with a sweet camo print, and wore my mag pouch the next week at training. It sat comfortably on my hip, concealed well (camo print aside), and retained my magazines with a well-dialed in retention. I was given tools to adjust if needed, but was happy with where it was. Excellent product. Appreciate them walking me through the selection, options, and transaction. Highly recommend!

    MRD Double Mag Carrier

    The mag carrier is amazing. The user adjustable retention is a must for any mag carrier. They hold the mags securely and even turning the carrier upside down and shaking it doesn't cause the magazines to fall out. The black multi-cam looks amazing.
