BudsGunShop.com - Is the 686 plus deluxe a Round butt or square butt

This is the round butt frame, also any other post-1996 manufacture 686 should be round butt as well.

It's a round butt frame but you can get square butt grip conversions for it. " VZ Grips" makes several really nice grips in both round and square made from G10 composite that look beautiful on this gun.. I have the black/black squares on my 686 and they work great. Nice guns.

all new S&W revolvers are round but Smith has grips for the round butts that feel like the square butt

Charles, round and round she goes, where she stops. now you know. Cheers and stay safe Sir!
