i found some at cost about two weeks ago. they were out of the 4 set, but i got the 3 and has been doing great for me. the store was called kempf gun store somewhere in michigan. the have a website, but make sure you call and make sure its in stock before ordering online. hope that helps. btw...the are about 40$ shipped, and showed up in 3 days. and you can always find the 4th die sold seperatly, its in stock almost everywhere
