Another update for the 1-2 people that actually care. I will probably finalize things here once I get Diz's pouches.
SOE Triple Shingle: It's lined with velcro so I put KYWIs inside if I jump or am swimming, combined with the bungee retention, it's great. Run S&S tabs on it. Seems bombproof. I count 3-4 lines of stitching in the stress areas, SOE states genuine 1000D cordura. Great mag fit. Perfect ride depth, protects 90% of the mag and leaves enough room for a good draw in gloves. Big fan for sure. The KYWIs seem to be a little more compressed since the pouches are tighter, so they don't stick out a lot. Easily removed if needed and I just want to run the bungee. This seems like an ideal setup right now.
Tyr Triple: Great as well. Mags seem like they ride a little looser. It's lighter than the SOE. Need to test more. I read something about the adhesive between the kevlar and the cordura having a relatively low melting point of around 150deg (F). The hood of your car can get hotter than that in the sun... I'll need to look into it a little more.
BFG Triple Flap: Great simple pouch. Velcro is loud but for a flapped magazine pouch, I would say this is the best option out there. Flaps are tuckable. Mags are a good fit, not too tight, not loose... Big fan of HW and the UltraCOMP, it's low profile yet still seems durable. I reckon I will keep this pouch and use it interchangeably with one or two other choices.
Esstac Mid + Tall: I like this pouch but I've found more success running the SOE with KYWIs. For my line of work I'm slightly concerned about the open-bottom KYWI pouch. If your Kydex ever failed or the adhesive of the velcro melted off, your mag is going for a ride. I think Esstac pouches are absolutely perfect for range or SWAT/LE though. I don't believe in using gear on the range that I won't use on ops, so it's a no-go for me. That being said I run a 2x1 on my belt and know a lot of guys who do.
FirstSpear Ranger Shingle: Also seems like a good option but I need to test it more. It's nice and low profile, easy to use, seems like your standard pouch honestly. Good quality.
S&S Precision Triple Pouch: This thing screams tacti-gucci. Made of 4-way stretch with S&S flair. I think this would be a good fit on a JPC or low-profile rig. I don't think I will use this for assaulting or .mil ops.
Still waiting on Diz's pouches, he's at SHOT Show right now. Once I receive those I will be able to finalize what I will be running.
