That gun could have shipped with magna or target grips. It doesn't matter which you use. You DO need to figure which style feels good in your hand. Once you do, go for it! Grips, obviously easy to change. I have found nice used sets on ebay. (prices have been going up) You will need K/L square butt grips.
Look carefully, read descriptions, & ask questions if need be.
I got my 14-3 early August. It came with target grips. A tiny bit beat up.(grips only) I put smooth targets on it for a few weeks while I did a refinish job. Originals are on now looking pretty darn sharp.
So anyway, make sure that you tell us about the 36-1. Bob
