'Bout 100 vids on YouTube in the past few weeks on the new Ruger 57. Looks like an interesting round for a handgun. Not sure of it's practically for carry gun but I'd like to see and shoot one. I expect Ruger eventually come out with a rifle for that round too. I guess the 5.7x28 has been around a long time but wasn't popular and was expensive. I just wasn't familiar with it.
