I just purchased a 9mm 247PRO. My boss has the 45 24/7. Unless that dudes gun in the video was tampered with and removed the saftey internally, I find that very awkward. My boss' gun does not have that problem with his safety. I've heard people bash the Taurus name cuz it is "newer", whatever the case may be... I have not met someone who has had trouble with their 24/7.
Also, take this into consideration. When I decided to buy my 24/7 from my personal gun dealer... 24/7 is the greatest value deal around.... he could have made a bigger profit pushing me towards another brand. But he didnt. when I told him i wanted the 24/7, all he said was... that is a great gun, they have been purchased a lot and everyone has loved them. No negative feedback.
So, if you can buy from a legit dealer who isnt trying to smuggle a used but super clean gun into your hands... I wouldnt worry about it. Plus, it has a LIFETIME warranty if anything goes wrong.
BUt that is my experience with the 24/7s. I will challenge a someone to a draw on a target with my 24/7 and i bet mine will fire just as well and reload itself as anyone elses haha.
