I was surfing through doubletapammo.com site. And I came across S&W .40 200gr bullets. I was surprised with the grain weight of 200, I own an M&P .40. So, I've got two question for anyone with 200gr S&W .40 experience. 1) Has anyone shot it with their M&P .40? and if so, did it work flawlessly. (2.) And What do you think of its efficiency when it comes to personal defense bullets? Feedback will be appreciated!
