I mentioned this in another thread some time back. Carefully remove your target stocks and install a pair of magnas. I did so on my 5 inch 27-2 once and they remain there today. The balance, feel and overall appearance is near perfect IMO. I have always preferred magnas on short barreled N's and targets on 6/6.5 inch and greater guns. To me, the target stocks look out of proportion on the short guns. My 29-2 4 inch now carries magnas, as do a few others I have. I also, again just for fun and variety, put a set of magnas on my 25-2 6 1/2 inch with the high partridge front sight. It looked remarkably like a triple lock or early hand ejector.
Again, I just prefer the look....makes them appear longer and sleeker. Also changes the balance point and each handles differently. Warning- not recommended for shooting hot loads.....just for the pleasure of handling and appearance!
