Very handsome indeed
I remember reading that the "Six" family were designed with their frames deeper behind the trigger guard to eliminate having to add aftermarket grips. But handgunners being who they are, everyone wanted grips that fill in that area...so Ruger offered the larger "target" grips to meet market demand.
I sort of inherited (through wife) a blued Ruger Speed-Sic with the 2.75" barrel. The receipt that was in the box read $158.
It was bone stock, so I thought I'd try out the reputation of the grips to see for myself. They weren't very hand filling, but they did allow a correct grip aligning my trigger finger with the trigger. I dug out some Safariland K-frame speedloaders and grabbed 200 rounds to shoot in my local IDPA match that weekend.
The Speed-Six shot fine, not missing a beat and was even zeroed for my 160gr polymer coated competition loads. The grips pointed well and didn't interfere with reloads. The only ;limiting factor to better performance was that the trigger was a bit heavier than my usual 686 and the sights were a little harder to pickup out of the holster.
Granted this wasn't with .357Mag ammo...I don't have anything close loaded in the garage...but I thought the grips were more than serviceable
