I am a LEO and would like to trade in my off-duty S&W 38 airweight for something with a bit more capacity, probably in 9mm. I have thought about the Walther PPS 9 and S&W M&P 9c. I want something very light weight and easy to carry, but don't want to gain just 1 or 2 rounds (5-7). Reliability is key and price does not matter for this will be a long-term upgrade. Thanks to all who respond. Suggestions are appreciated.
