I have to agree about the 24/7 trigger. I just picked up a new one last week for $340 and it's one heck of a lot of gun for the money. Basically it's an upsize of the PT111/PT145 Pro, two guns that I hold in very high regard. While I haven't fired the 24/7 yet I can say that in dry firing it is the best Taurus trigger that I've experienced. My PT111 MilPro is DAO and I thought that was a great trigger and then found an even better one with my SA/DA PT145 Pro, and now the 24/7 seems the equal or better than that. The presence of a manual safety really makes me happy.
As to the downside, as to the gun itself, other than what I've heard about occasional lemons (no personal experience on that, only hearsay) I find the price of Taurus magazines to be a bit on the high side. I like to have at least five or six mags for each gun that I own, so mag prices are a concern to me. The other issue is warranty work. Taurus' customer service has some weak points. You'll hear varying reports but you should be prepared for the possibility that they will hold on to your gun for an inordinate amount of time. Also, I have personally found their phone customer service little more than useless. Others will have had other experiences, but a prospective gun buyer should be aware of these potential issues. I fully expect Taurus' customer service to catch up with the excellence/value of their guns, but if a Tuarus is to be a first and/or only gun I would chose a brand with better and more timely warranty/customer service. If you have other guns to shoot should there be downtime, to me the Taurus is the best value going in the gun world.
Oh, one other thing about the 24/7 that I don't like. The ribber grip forces your fingers into a particular hold. Many guns do that and that particular finger placement may not be best for a particular hand. When I hold the gun with my dominant right hand it feels just a little bit funny, and with my left hand it feels perfect. I also find that the seam where the rubber ribber grip meets the frame is just a little low and could benefit by being just a tad higher towards the junction of the triggerguard and frame. To me this is a minor subjective point, and possibly they tried a different placement and chose the one that was best for the most folks.
