In the video I saw, he was shooting offhand. Doing pretty good, too! If I were just getting my first .22lr pistol, the new Mark iv would be very tempting. Hopefully, I'd know enough to see merit in the new design.
However, I'm a target shooter and very few mfg.'s offer a really good trigger in their basic pistol, in that price range. Ruger included. In fact, Plinkster commented about the Mark iv trigger.
Give the aftermarket some time and we'll see some nice stuff for the Mark iv. Meanwhile, I'm hoping the Mark iii Hunter will drop some in price. It would be a great companion to my Mark ii Government Target, Mark iii's- Target, Competition Target and TALO Hunter.
I shot my Mark ii on Thursday. Extremely accurate gun, much better than I am. I shot one 5 round group of 1/2" dia. (the other 85 shots weren't as good), offhand at 15 yards using a C-More red dot. My Hammerli Xesse Sport with a C-More and my S&W Model 41 with an Ultradot can do better, especially if fired by a better shooter.
