I own examples of different Glocks and M&P's, and I've also been through armorer classes (and recerts) for both brands. Both are fine examples of good quality service-type pistols. I recently had a chance to shoot a new production M&P 9 Pro 5" model. I usually don't focus a lot of attention on the subtle nuances of triggers, as I'm used to using, owning and carrying a variety of different personally-owned and issued guns ... and I'm not a competition shooter ... but that 5" Pro had an outstanding out-of-the-box trigger compared to most M&P's I've been shooting. Nice. Much nicer than the last G34 I handled and tried out (belonging to another guy at my agency). I'm also another owner/shooter of the Walther 99 series, and the licensed S&W versions, too. I carried one on-duty for a few years. I've been through the SW99/P99 armorer class a few times and have helped support a small number of SW99's & P99's for several years. (Only a little over 50-60 guns, counting issued & personally-owned guns, so it's not exactly a large number.) I've seen a few broken ejectors, damaged springs, end caps, sight bases and even had an out-of-spec trigger bar guide, but I've not seen the sear housing block break apart as shown in the linked content. Granted, Walther's made some revisions over the years, a couple of which involved some dimensional changes to the older style blocks. More recently, in the newer 99 AS guns and the PPQ, Walther changed from using the post-style trigger bar guide to an adjustable lever-style trigger bar guide. To adjust the striker travel/timing of striker release in DA mode using the original post-style blocks, obtaining the correct timing might require changing to a different spec post in an occasional gun. (I had to do that in one of my own guns.) The newer lever-style guide can be adjusted via a screw, though. The sear blocks using the different trigger bar guide designs are NOT interchangeable, so Walther makes both styles for use in different production vintage 99 frames. FWIW, I've serviced some 99 models that have been used to fire anywhere from several thousand to more than 55K+ rounds, too. I think my SW999c (think P99 AS compact 9mm) just reached 15K rounds fired in the last year. If I were going to "choose" one of my assorted compact/subcompact 9's just for the smoothest, lightest and crispest "trigger", in both DA & SA modes ... of my pair of G26's, 3913, 3913TSW, CS9 & SW999c ... it would be my SW999c, hands down. (I've handled and used some M&P9c's and Shields, too.) Rather than overly emphasize any particular make/model, though, I prefer to put more attention on my skillset & training, allowing me to run any of them. It's not like any of them are ever going to "feel" like my 1911's, after all.
