The down sides to the Serpa on a leg rig are Serpa are these:
1) Other shooting sports such as IDPA and IPSC don't allow a leg rig
the serpa can be easily separated from the drop leg...so the holster itself can still be used for other sports. You will need the belt loop though

As an option here's one of my rigs, I'll be upgrading he belt to a HSGI or BFG by the end of the year and picking up some new TACOs or FastMags. I'm also looking at a G Code or Raven Concealment Kydex holster once money allows.

Sorry about the edits took me bit to sort out the link on the iPad.
Nice set up! I am doing similar thing.
I am waiting for the newest 5.11 plate carrier, and I will be running it with 5.11 mag pouches, 5.11 drop leg holster with the 5.11 thumbdrive holster. I am thinking to get another leg rig to attach Tacos on my other leg.
I'll say it again, don't put stuff on your legs. The leg holster is bad enough as its never in the right position and very much a PITA for the prone string, which usually ends up with it getting pushed around to the front of the legs where it's pretty much useless. This goes double for leg pouches. You don't need that many mags for CQB and good luck trying to reload from the leg on the move and shoot match. The rig pictured above us is good as any I've seen.
Find a place to try them out, if your close to One Shot Tactical they have both, if not there are a few of the other retailers listed above that have them or similar. The big difference in the two is price, the HSGI runs just under the $100.00 CDN mark where the Blue Force Gear is just under $200.00 CDN.
Condor makes one as well and it costs less, or if you find you really do like it as a set up places like SOE Gear, and Ares Gear, make custom ones.
That's one thing I'm going to change on my chest rig, I put two double mag pouches which gives lots of extra plus it's handy to grab those four for the prone stage, but most of the time it's just too bulky, I'm going to strip it down to two singles (maybe three) to get it to lay flatter. I went with a split front rig which is nice because in a normal prone I can just undo it and get right on the ground.Thanks, I learned the hardware years ago to get things off my legs and to keep my rig light. The belt is really the way to go for practical shooting or competition if you want to carry that much or even down load and just use the belt. One of the things a friend got me doing is as well is 1 pouch, 1 mag. Keeps me from dropping mags and is easier to take a prone position because everything isn't cutting into me.

I was looking at reviews video on youtube on BFG SOC-C padded belt & HSGI padded belt. In term of functionality, the only difference between the two is SOC-C belt is adjustable to your waist, and HSGI you have to get the exact size. Are there any other differences that I missed to justify that extra $$$ other than the brand name?
If I had to choose a drop leg unit, I would prefer the 6004 or 6005 Safariland with the SINGLE strap shroud or cut down your double strap unit into a single (lower) strap setup and have it seated nice and high off your rigger or instructor belt.
Now back to the drop leg, I do have them and wear them occasionally, but I prefer my holster on my vest because I'm worried about 'fishing' for my pistol at the bottom of the blue shztter at Langemark Range, CFB Borden. The drop leg rigs are a PITA for those moments when Nature Calls and you have to drop a deuce. The last thing you need is me yelling, "Desert Eager, number ONE!"
Seems to be a popular cheer at CQB events in Ontario!
Hey, my Serpa should be here soon, and yes we don't bother loading the chamber until after the pistol is drawn so I think my #### won't get shot off.
Cheers,

Actually I'm running three Helium Whisper doubles but I only put a single mag in them, I find they elastic is tight enough to keep them firmly in place. I'm also running the Ten Speed side panels for extra space if I really need it. Even the 5.11 pouches on my belt are the double stacks I fold with the flaps in and they hold a single mag perfectly.
