I had a M&P9c before I got my 9mm shield. The 9c had the same footprint as the shield and is just a bit wider and heavier. One range session is all it took for me to know that (for me) the 9c was a way better choice. It was SO much easier to shoot accurately in rapid fire /double taps and was allot more comfortable in the hand while doing it. The shield went up for sale less than a week later. Since then I've bought a 45 shield nut still think the 9c (1st gen) is a great choice for it's intended purpose.
