I just recently did the same thing. I have been carrying various Glocks, both on duty and off duty, at my PD job for ~25 years. After several instances of absolutely horrid customer service over the years, I started looking for something to replace them. I always loved the ergonomics of the M&P line, but the older ones had such bad triggers that I never got one (we aren't allowed to do internal mods that aren't factory approved, so Apex-ing an M&P was out). A friend brought a 9mm Shield to the range for qualifications right after they came out and let me shoot it. I bought the first one I could find (took a while, they were VERY hard to find) and bingo, Glock 26 replaced. Still carry it off duty to this day and, in fact, have it on my hip as I type.
When S&W announced the M&P 2.0, I was VERY interested, especially after finding out about the improved trigger. I scraped up the money and bought one a full sized 9mm couple months ago. After the first trip to the range, I bought a duty holster for it and am currently waiting on someone to be able to take me to the range to qualify with it. When I do, the only Glock I will have left for carry is my Glock 42. I have large hands and an LCP is too small and I just can't stand the HEAVY trigger on the Bodyguard .380. Are you listening, S&W? Come out with a Bodyguard 2.0 and, preferably, make it striker fired, or at least with a lighter trigger, and I will buy the first one I can find and be Glock free.
And, before you ask, the triggers on the 2.0 M&Ps are VASTLY improved over the 1.0s I have tried. The take up on my 2.0 started out gritty, but that has gone away with use and cleaning. The take up is smooth, you hit a well defined wall and get to a pretty crisp, reasonably light break. Not 1911 crisp, but very good for a striker fired gun. The trigger reset is audible and tactile and, to me, feels very Glock like, making for an easy transition from Glocks. The ergonomics are outstanding and the gun fits my hand VERY well. I think it is a worthwhile transition to make. Good luck with your decision.
