As Curtis said, tight grip usually means less trigger control and so accuracy. I've always shot Contenders and Encores (and all other handguns) with a light hold, including the meanest of the mean handcannons, just went with the recoil/torque and let them roll. Never dropped one, never got hit in the head by one even though some of the baddest boys came well past verticle. I didn't control them anymore than needed to stay on target and not drop the handgun before the shot... and then I followed them. Allows you better trigger control, and if do feel you need a stronger grip, time it for after the shot. You can also use your off hand to support, but not grip with it and that helps you have a lighter hold. The 44MAG even in a 10" octagon barrel is not bad if your grip fits you right. I used to have a 44MAG CCW with a 3" non-ported barrel that makes the TC a real pussycat in comparison. Custom wood to fit your hand, or Pachy Gripper Decelerators tames a lot of recoil and torque for most shooters. They are small for big hands maybe, but they still do the job just fine even if only a three finger hold.
A little story... when the Encores first came out I jumped in getting some from the first batch of 80 received at Bullberry, started with a 454 Casull and 22-250 barrel - one short, one long. I shot Freedom's hot 454 loads in their revolvers I had for IHMSA, so I also used them for the Encore. With the factory grips the Casull was brutal because the factory grip did not fit my hand worth a hoot. Not the recoil, the torque. Had Bullberry make me an Encore grip that did fit my hand perfectly (with a matching forend), and it came along with a 10" 416 Rigby barrel from them I had ordered. With the new grip the Rigby was a pussycat compared to the Casull with factory grip, and now the Casull was like shooting a rimfire in comparison.

As said, scopes/mounts add weight that may or may not be beneficial to perceived recoil. And they add mass/weight that can get you. Personally I never scoped my 10" TC barrels, octagon or otherwise. They were my open sight shooters, the 14"/15" all wore scopes though. I have never been a fan of brakes either. A few of my JDJ's had brakes (but none of my Super Bowers), only because I bought 3-4 used that had them. I never ordered new with a brake. Can't say I have even seen a 10" octagon with a brake in 44 years, but I guess it could be done, at least M-N-P slots by Larry Kelly.
