If I were going to choose an all-steel 9mm pistol destined for a lot of use I'd pick up a 5906/5906TSW. I'd think it not unfair to categorize them as under-rated 'workhorse' pistols. The 3906 would be a close runner-up, too, even though it's a single column model.
I'd think the Browning HP could also be considered a viable choice. Their reliability with feeding JHP ammunition might be variable, though, depending on the particular pistol. You can also hear of different experiences regarding the magazines.
I have a copy of a FBI Academy Firearms Training Unit report titled Semiautomatic Pistols 1987-88 (which I received when I attended a LE firearms instructor course in which the FBI was involved). It discusses the results of in-house testing of several 9mm service-type pistols popular back in the 80's. While the Browning wasn't included in the testing, it did note in the commentary section, for comparison purposes, that the Brownings used by their HRT (at that time) had over 80,000 rounds through them and were still considered good (notwithstanding replacement of barrels and small parts).
Although I've handled and used Brownings with good results ... (I have a friend who used to enjoy working on them, and kept a nicely tuned example which reliably fed JHP ammunition and exhibited excellent accuracy) ... I don't care for them, myself. However, that's not to imply there's anything 'wrong' with them, only that they don't particularly suit my tastes. Different strokes.
Although I can't remember spending any range-time with one, I'd think the P226ST might deserve some consideration, too.
FWIW, I've always wished that S&W had offered a stainless steel-framed version of their excellent 3913 model. A '3916', as it were. Such a model would have a good chance of becoming my choice in the 'one & only' 9mm defensive pistol category.
