So I finally picked up a Model 14-3 a few months ago for $600 AUD. This 14-3 was already a single action only. I already had a custom made grip for my Model 14-6 but this was now a full time Service Match gun since I had installed an Aristocratic Sight Rib.
The Model 14-6 is a Round Butt while the Model 14-3 is a Square Butt. So after a little Dremel work, I was able to modify the grips so they would fit. Here's the finished product.
