Glocks get the reliability nod because they have been around so long. They make a gun that works and doesn't change the name; just minor tweaks. The M&P is an excellent and reliable gun but without the longevity factor to show. I fear it never will be either. Most other companies can't go without changing names and models ever so often. So our M&P's probably won't be made in 10 years time, never getting a chance to become long term reliable. The exception is the J-frame, at least for now.
