It seems to me that sometimes it's entirely appropriate to ignore the safety on a gun.
You're free to do whatever you want, it's a free country
I actually got rid of my S&W 908 for that reason. For a DA/SA pistol I prefer just a decocker. That's why when I look at CZs I look at the decocker only models.
Let's also keep in mind we're not talking about any of those weapons. We're talking about a S&W M&P that is available in versions with and without a safety. If you don't want the safety, just have it converted by a S&W armorer or gunsmith. I bet if you called S&W they'd do it for you.
