So that it's more like a Glock.
For over three decades now Glock has dominated the auto handgun market. Eventually every manufacturer ended up with a Glock copy of some kind. S&W was no different and they had to pay Glock for copying their gun with their Sigma. The M&P is the “evolution” of such a pistol, so basically the M&P is a nicer looking Sigma, which is a copy of the Glock.
Now here’s the funny part. It seems that if you want the latest tricked out M&P you can customize it by adding this $140 Apex trigger kit, so as to make it a state of the art handgun by well… putting a Glock trigger into it.
Don’t get me wrong, I’m sure it DOES improve the M&P , but it is hard to avoid noticing that it does so by putting a Glock trigger in a striker fired polymer framed gun that copied the Glock on everything except for the trigger.
People, I like most guns, there’s thousands of great designs which do their intended job and are fun to shoot, but if you want the best defensive auto pistol there’s only one way to go and one gun you should master. The rest have simply been trying to reinvent what Gaston Glock got right the first time.
