Man, you found a good looking revolver.
It's not my intention to mess with your productive groove, so turn your head away and do NOT read this next paragraph to avoid corruption!
Okay, I see that you are reading anyway!
Just wanted to say that if you polled a LARGE number of Smith & Wesson revolver-philes, you'd find a
very large portion of us just don't care for the feel of original OEM Target walnut issue stocks on the revolvers of this generation.
They look pretty darn good, in my opinion. They put them on a slew of K-frames and all of the early L-frames, my 686-3 (1989) came with them also.
I yanked them off before the revolver fired it's first ever shot. Back in the 80s, everyone was enamored with the Pachmayr Gripper rubber grip. Colt even put them on King Cobras and Pythons!
So that's what I fell in love with in my formative years and I still love them, though they are as dated looking as a "Flock of Seagulls" hair style.
There's a zillion options for grips and it can be tough finding something different if you don't find them already attached to K-frame you can hold in your hand for "feel."
But my point is that many, MANY folks shoot K-frame Smith & Wesson guns
better, when exactly those stocks yours is wearing (and looking great with) are tucked away in a shoe box of unused gun parts.
I'm sure a -LOT- of folks do awfully well with 'em just the way they are, and I've got no struggle with that, either. I actually kept 'em on my Model 17-6. Nostalgia has value, too.
Smith & Wesson has since gone to a grippy, greasy and swoopy looking Hogue monogrip. I can admit that this grip feels nice in my hand, but it's wretched looks make me wanna upchuck. It's like looking at my favorite 80's era Pachmayr, but while I'm tripping on acid.
But they feel pretty good in the paws.
Anyhow, I'm glad you didn't read -ANY- of that, because you are shooting pretty well with the original walnut Target Grips, so everything is good to go!
