I've carried everything from a 1006 Smith and Wesson through the Glock 9mm and 45 lineups, the S&W 9mm M&Ps and Shield, a Kimber .45 and finally the S&W .45 Shield. I have RMR-equipped, heavily modified Glocks which I love dearly. For a variety of reasons, I have wound carrying the .45 Shields almost exclusively for well over a year. They shoot as accurately and reliably as the others, both up close and at distance and are much easier to comfortably carry and conceal. I own two production models and one Performance Center offering. If I could only have one handgun, it would be the .45 Shield.
