M&P9 safety or not?

[GD2A]

Hmmm ... perhaps I was right to walk away. These comments do not inspire confidence. The wallet and principles came to terms but my gut overruled after considering purchasing a Pro but seeing the comments. Maybe there's more to the crazy low prices than meets the eye. I did try and contact the company to verify but ran into their hopelessly poor communication.

With $435 seeming to be the best price for a base M&P9 from a reputable vendor, the Glock 19 is looking better for $100 more. PSA has a deal right now on a Gen 4 with a range case a factory 33 round mag thrown in.

Any thoughts?
