Empty Quiver. Wrong, the Sig 225 is still being imported by the thousands as used guns. CDNN Sports of Abilene, TX, PH 1-800-588-9500 has them in their latest catalog for $299.00, an excellent buy in my opinion.
I have two of them, one was a bring back from my military tour in Germany, the other I purchased several years ago for another GI who brought it back. The downside to the 225 is there are few magazines available, and when you can find them they are expensive. (CDNN had them for $24.99, but someone bought every one that was available, over 6000) Next the magazine release is located on the bottom of the gun which makes it a little more difficult to change in a SHTF situation, this can be done fairly quick with practice. The next downside is the limited number of rounds it holds.
Even with all the flies, they are excellent guns, and should serve as a great carry or personal defense weapon. I don't think you will go wrong in buying one of these guns.
Unless you have an FFL you can not purchase directly from CDNN. Some FFL holders that are registered with the company may allow you to order and pay for the gun on your personal credit card, having the gun shipped to their address, and they charge you a nominal fee for transferring it to you.
