Well, I got my new MKIII Standard 4 3/4" out for some extended shooting yesterday. Man, this pistol is accurate! I started out shooting those evil soda/soup cans at about 15 yards and then I really wanted to get some distance in. I decided to move out to 30 yards. I was hitting my targets consistantly and this was with cheap bulk ammo. When I first ordered the pistol I was a little concerned with it having fixed sights but I have been completey happy with the purchase. The only problem I had was the mag release was binding on the modified MKII grip I fitted, causing the mag to sometimes not have a positive lock up. When the pistol would lock back after the last round, the mag release button would partially stick. All I had to do in the field was drop the empty mag, close the bolt and then the button would re-set. So when I got home I just had to do a little more trimming on the inside of the grip panel with the ol dremel and now it seems fine. This is quickly becoming my favorite pistol to shoot! Next time out I want to try it at 50 yards. I love pushing these 22's just to see what I can do with them.
The take-down and reassembly is initially challenging and/or frustrating, but the learning curve isn't terribly steep; especially after viewing a few videos. Like the grips on yours.
