I've bought a few guns before firing them.
3 of the ones on your list, actually:
2. Springfield XD subcompact 9MM
3. S&W MP 9MM
4. Glock 26
I love all 3 of those. My personal favorite is the glock (right now), but they are all great shooters and fit my hand well.
I sold my fullsize m&p to get the g26, the smaller size is totally worth it. still shoots great, and conceals MUCH MUCH easier. and i'm a big guy. the G19 is only slightly smaller than the fullsize (4.25") m&p, that's why i went with the 26.
However, I've also bought a few others without shooting them first that didn't turn out too well (CZ82...cool gun, but I just couldnt shoot it well from the get go. didn't invest too much practice in it, either).
IMO, as long as you know what you like, and you have an idea of how you shoot and what is comfortable, it is possible to buy without shooting.
However, nothing beats the assurance of shooting before you buy to make SURE you'll like it the best.
