I believe you bought a Galco FED paddle holster for a Beretta M92 from me off THR's Trading Post. My username there is Skytrooper. I have seventeen new 20-rd Armalite AR-10 mags for sale in the AR-10 EE forum @ $39 each shipped. My username on ar15.com is AbnInfantry (someone else evidently already had Skytrooper when I registered). I'm already selling the last of my AR-10 mags for less than my cost, but if you want several, I'll knock off a few more bucks.
I also have two new preban factory blue Beretta M92 mags and one preban nickel M92 mag made by Mec-Gar (as good or better than factory). You may have all three for $70 shipped, if you're interested.
