I shot every poly-framed .45 in the rental fleet at my local range, and ended up with Glocks. I shot the G30 far better than any of the others. The XD models that I shot were too aggressively checkered to enjoy. The M&P was very good, but the G30 just made me grin. And the speed and accuracy are both way better than they should be.
I now own a G30, a G30SF, a G36, a G21, and a G21SF, all Gen3 guns. The G30 is still my favorite, but none of them are for sale. I prefer the full frames, my 123lb bride prefers the SF models. Here in CA, we're pretty much limited to 10+1, so the higher capacity of some of the larger guns was moot. The HK and FN offerings were not appealing by comparison, regardless of price. Heck, the Baer SRP I bought last summer cost as much as all 5 Glocks, or a FN and a HK, or a couple of Sigs....
