A little help with shot grouping...

I took my "new" 1937 S/42 to the range this weekend and put 50 (115-grain Winchester) rounds through it using an original Type 3 Army magazine. I'm happy to report that it fired all 50 flawlessly - no jams, no misfires. As you can see from the photo below, I was able to keep the grouping pretty tight at 25 meters (I'm blaming the ungrouped shots on sheer excitement!). However, all rounds went below and to the right of center. Is this just operator head space and timing? Is it possible to adjust the sights to "zero" the weapon? I was able to walk the groups closer to center by compensating my sight picture. Any shooting tips and advice would be greatly appreciated. Take care...Denny
