I believe the Combat Masterpiece could be special ordered with target stocks. I doubt many were. A photo of my Model 15-3 with walnut target stocks is shown below.
It depends on what the buyer wanted, target or magna. I prefer targets, but that is just me. Put whatever feels right to you on it. Grips can be changed in less than a minute. Can't have too many sets of wood grips! Bob
Yes. Here's a 15-2 with factory GA stocks. These are not common.
Notice this one has all three Ts. I believe it came that way. I received this one as a gift from my dad a bunch of years ago.
Depending on which variant of the Combat Masterpiece that you have, those targets with the speed loader cutout might not be right for a Model 15.
