Anyone know where to find these ? I'm not so concerned about authenticity, but want one that functions well.

www.e-gunpartscorp.com

There's always ebay.

If they don't have it, there are message boards more oriented toward surplus / military rifles and such. A google search ought to dig up a few.

Welcome to the forum!

I would try Sarco, Inc. at www.sarcoinc.com, Midway at www.midwayusa.com or Cheaper than Dirt at www.cheaperthandirt.com. Some folks have had good results with Gunparts, Corp. However, everything I have ever ordered from them was unaccecptable and was returned. All the best...

I also own a 1912 DWM Luger with original mag. Ordered 2 replacements from MidwayUSA. Work great. John
