There are tons of good .40s out there, even if you don't like Glocks. Beretta, SIG, HK, S&W, Springfield, CZ, Walther and others make high-quality .40 pistols. Best idea is to find a range that rents guns so you can try some on for size.
Soon JeffWard will be along to sing the praises of the XD, TOF will pop in to recommend the M&P, and Shipwreck will tell you the P99 is the best.
And someone will point out that I omitted Taurus.
