Love my .45 XD and what the bullet can do for defense but I just bought a 40 cal XD and have to tell ya its been a blessing. I can find ammo everywhere. Im burned out trying to find 45 ammo. If you get lucky and find it you pay for it also. Just bought 15/50 rnd boxes ($13.50) Federal of 40 from 3 different stores. Was talking to a guy at the gun shop who just went to a gun show were he only found 2 people selling 45. They were asking $45.00 for a box of 50. Its still one of my favorite rounds but I think the XD45 is going in the gun safe until this crazy crap blows over. Until then my 40cal will work just fine.
