Works great in my S&W 929. Fits fine in 3 different moonclips. Easy to load. I'm on my 6th reload of some of the cases and they still look new.

I have used Starline 9x21 brass in my USPSA Witness comp pistol for over 10 years. This brass always chambers, and takes primers with ease. The brass holds up to several reloads for both competition loads and practice. I rebarreled my Witnes several years ago with 9x21 to hit Major loads. but now I use it for down spec'ed loads even for steel matches. Great stuff. But you guys REALLY need to start making .223/5.56 brass!!
