For me it is simply a matter of size. I like the way targets look on a
4" or longer barrel but they seem to overwhelm a 3 1/2" gun. But target
grips, N or K are just too big for my hands and so all my Ns and Ks
wear magnas. If I get a new N or K frame with targets on it I remove
them imediately before firing the first round from the gun. I know that
some people don't like them but I have found that a nice pair of factory
magnas can be hard to top with any after market grips.
