Well, mate, my first choice would be a 1911. You've got loads of different models to choose from. My favourites are ParaOrdnance double stacks and simple, no frills, Colts (basically, give me a 1911A1 with better sights and I'll be a happy camper). What I love about Paras is that they fit my large hands very well, and you get twice the magazine capacity of traditional 1911s. Do you need 15 rounds of .45? Probably not, but it can't hurt.
They are fantastic house guns, a bit big for concealed carry (that's where slim, single stack 1911 shine).
The design is as time proven as it gets, there are lots of parts to customize it or replace anything that breaks. Once you get used to a nice 1911 trigger, everything else seems crude. My Para P14-45 is far from being a race gun, I haven't changed anything on it yet, and I still feel more comfortable with it for long range shooting than with my S&W M&P.
Another platform I would consider is the Sig 220. I tried one out and loved it, it was quick to point, really accurate and comfortable. The only thing I didn't like was the double action trigger pull, if the SAO (single action only) model were available in my country, I'd get one in a heartbeat.
There's also the CZ97, like all CZs it's very well made, tough and accurate. I love its looks and how it shoots. It's big and heavy, though.
