not to sound like a ding dong but what is 3 gun match? run and gun with 3 guns??
That's pretty well it. Except that knowing Farmboy/BadBoyBeeson/6GMG6, you would have to fire either from cover or on the move and only reloading from cover.
And I would fully expect the requirement for transiting from a long-gun to a pistol on the fly, which would entail letting a rifle/shotgun hang in front of you while you do your thing with a pistol.
Now, what am I running...
For this match, I am not quite sure what kind of a rifle I would be running for the "long-range" portion;
My 16" AR with an EoTech sight and a Vickers sling (BlueForce Gear);
Rem 870 Express with a Knoxx SpecOps stock, firing Chemist' amazing low-recoil slugs (which when combined with a "pussy stock" have absolutely no felt recoil)
Kimber Custom TLE II for a pistol.
Now, there is of course a rig to go with that, and I have to say that all of it is right from OneShot. I have something about supporting a local business, especially that of someone I actually know and who supports both the troops and our sport.
The holster I was going to use was a BlackHawk Serpa Level II drop-leg holster, very much standard.
The chest rig is as such:
VooDoo Tactical Universal LBE Harness;
On the left:
ATS Roll-Up Dump Pouch (for discarded partial mags, and keeping my "Barney bullets and in-weapon mags while waiting to approach the line);
VooDoo Tactical Universal C6/C9 pouch (for the shotgun shells);
On the right:
USGI quad pistol mag pouch;
ATS Triple mag shingle;
ATS single M4 mag shingle.
All in all, the load-bearing rig complete (including the holster) rang me about 350 bucks all said. Not overly expensive when you think that a single mag pouch for a dedicated IPSC rig will ring you about 50 bucks each and you'd have anywhere from 4 to (lots) around your waist.
