CDNN had Mec-Gar LE marked for 23.99 and Asian contract mags for 13.99. http://www.cdnninvestments.com/beretta.html
I don't know if thats any good now as I haven't bought pistol mags for quite awhile. If anyone knows of a good source for CZ-75 mags please post it.
I have found the Mec-gar mags to be very, very reliable.
If I'm not mistaken, Mec-Gar makes some of the mags for manufacturers like Sig-Sauer, Kel-Tec and some others.
I have used Mec-Gar mags in my Sigs and find them just as good as any mag out there. They are the only aftermarket mag I will use.
You can get factory Beretta or Mec-Gar mags for the Beretta 92's at most gun shows.
I bought a Mec-Gar (Nickel) Beretta 92 mag at a show last weekend for $24.00 and it works great.
I ran about 4 different types of H.P.'s thru it and then loaded it up in my bedroom gun.
I trust it that much.
