I have a poor-mans's version of the Maxpedition worn horizontaly on my belt. It goes left or right depending on when I remember to put it on, LOL.. I was going to get the Maxpedition when I noticed that the Maxpedition has adjustable velcro tabs as the loops for horizontal carry, and if they're meant to rip open ever, on me it will.
I've lost and destroyed so many cell phones over the years, and had every kind of clip and holster fail me, that I needed to make something absolutely bomb-proof. (Or more correctly, seatbelt and chair arm rest proof) Pocket carry is pretty good for that, but I hate having uncomfortable lumps when I sit, and I don't like keys and change scratching up the phone.
I was going to use the holder I "made" on a temporary basis until the Nite Ize came out with the new line, but this has worked so well, it hasn't needed replacing. And even the Nite Ize has some potential "points of failure" for me. Magnets and velcro can come undone, or get ripped open. I wanted something that would rip my pants, my belt, or crush the phone before it would open unintentionaly. If I could get the bomb-proof closure of my modified pouch with the extra EDC loops of the Nite Ize, I'd be in heaven, but for now the closure and retention is a higher priority.
On a previous cell phone holster thread, another poster here (I forget who, and am too lazy to search, sorry. Speak up if you recognize yourself.) put me onto the "AWP" brand toolbelt phone pouch from Lowe's. It was only $4.00. It was typical black ballistic looking nylon, and had a velcro closure. On the back it had a rivited metal belt clip similar to a tape measure for vertical carry, and under that a broad piece of nylon webbing for horizontal carry. (my preference)
I used it until the velcro started to weaken a bit. At that point I put the second phase of my plan into action. I had a cheap freebie laptop bag from a conference, and I cannibalized it for it's fastex-style buckle and a short piece of nylon webbing.
I carefuly unstitched the positive fuzzy velcro patch from the face of the AWP's body to get it out of the way, and I then cut down the flap with the negative velcro hooks that closes the holster. Then, using a piece of the nylon webbing from the laptop bag, I secured the female fastex buckle to the body of the AWP phone carrier using a curved needle and black thread. Then, I looped the cut down flap through the male end of the fastex buckle and stitched it over onto itself.
So now I have something pretty close to the Maxpedition, but with no points of failure.
My current phone is a beat up Sayno with no special features. It was my wife's after I lost my most recent phone last spring. The deal is that whenever I lose a phone, she get's the new one, unless I can hang onto it for 18 months until I can qualify for the free $150 from Sprint to re-up our contract.
