Its been awhile since I've posted here, but felt the need to relay my experiences witht eh Shield 45. I purchased mine years ago, mainly because I'm a 45 ACP fan. After purchasing the Shield, I was amazed at how accurate this "pocket pistol" is! I can shoot the Shield 45 as accurately as my Colt Government and Commander 1911s (which have fitted barrel bushings and improved triggers). My buddy was debating been the available calibers in the Shield model, so a group of friends representing 9mm, 40 S&W and 45ACP made a range trip together. After shooting all the caliber options, my buddy purchased a Shield 45. Accuracy and return to target lead him to choose the 45 ACP. Also interesting to note, the 9mm Shield was a Performance Center with porting. Sadly, my 1911's rarely see the range now as the Shield is first into the range bag.
