I had a 360 M&P and it was definitely a handful when shooting warm .357's. I liked the u-notch rear sight better than the one on my new 442. I like the idea of having a night sight, but in all honesty, it's a close up "point and shoot" weapon and I have yet to really get on board with the front night sight only idea, probably because I'm so used to having a set in the rear in order to get true a sight picture. It was nice though and if I ever got another, it would be a 340 instead.
