I have heard through the grapevine that alot of law enforcement agencies are going to the .45 . This could be part of the reason you can't find it , even some police dept. are having trouble getting it as well.

If you shoot even several dozen boxes of ammo per year, I suggest you look at buying a basic reloading package, reloading book and reloading components. There was for a couple years a shortage of some components like primers, but you can find them in abundance now. If you do, you can load, reload as much as you need and save $ started after about 1 year of loading/shooting.
