Resistance is futile.
You have received several recommendations to get a 1911. I own several, Colts, Kimbers and one Colt/Essex I built a long time ago. I have no real preference between brands, but will admit to being enough of an elitist that the little horsey on the Colt appeals to me.
My safe also has 18 S&W revolvers, a .40 SIG P229, an HK PSP and a S&W ASP to choose from for carry. With all of that stuff available to me, a 1911 in .45 ACP is my chosen carry gun 99% of the time.
That said, the 1911 is not for everyone. The manual of arms is a bit more involved than a Glock, HD or M&P. Many people just can't get past the idea of condition one carry (an emotional issue, not a practical one), and the grip safety is also controversial as unnecessary (I rather like it). The combat Tupperware is just simpler.
My next purchase will likely be an M&P .45. I am impressed with them. From the perspective of ergonomics and simplicity, they are very hard to beat. Felt recoil is mild, the trigger takes only a little getting used to and is more than adequate for IDPA stuff, the grip comes with 3 different configurations, sights are excellent, they have a rail for a light, etc. What's not to like? The only deficit I perceive in the M&P is that the factory has yet to come out with a .22 conversion unit for them. (I mean
come on, guys! Just do it!).
The HD has a grip safety, for which I frankly don't see a need in a "safe action" weapon, and they are only partly made here. Otherwise superb. If you must have a grip safety, this is the way to go.
The Glock reputation for reliability is inflated, but still well-earned. I would own one, but they don't fit my hand as well as other choices. Just remember that Glock owners have to be constantly prepared to be defensive over the gun's inherent ugliness.
