Wife and I both own P30's and find them extremely comfortable (and accurate) to shoot. Yeah the trigger isn't as good as a Les Baer 1911, but it's not meant to be, and the mag release isn't what a lot of people are used to, but that doesn't make it 'bad', just different (which I guess some people feel is bad, another discussion, however). As mentioned, people love to hate them, like Glocks, or any other 'popular' thing.
Best piece of advice, shoot everything you can once or twice to find out what is comfortable to you. Then worry about the name on the side. All of the 'big name' guns, Glocks, SIGs, S&W M&P, Colt, H&K, SA 1911 & XD are quality guns that will serve you well for a lifetime. Don't get hung on manufacturer's (or calibers) name.
