STEYER M40 .40 S&W 10 round factory magazine for sale. I have searched the internet and local stores and cannot find one for under $25. I am asking $20. It is in very good used condition and you save shipping and tax. The best way to contact me is to text me at 2o8-35two-24one3. Calls are ok, but I don't usually answer unfamiliar calls. Email is also ok, but I'm often slow to see them and reply.
