A few months ago, I called IWI in Harrisburg PA and ordered 4 Uzi 32 round Pro Mags to use in my UZI. They are backwards compatible made by IWI in Israel. We should include them as a version in the library. My evaluation is that they may be the best Uzi mags yet produced. Remember, IWI is the new IMI. RTG and a number of places sell them, I have seen them for less than what I paid.
