The HK P30 is an excellent weapon. If it fits your and well and you like the way it shoots go for it. I own quite a few HKs and have never had an issue with the guns, or customer service. If the M&P works better for you go with it. It all depends on works best for you and your shooting needs. The P30 can be carried concealed quite easily with a proper IWB holster. Good luck on your choice and enjoy whatever you get.
