Gotta agree with GB on the 'no brake'. 44 doesn't need a brake. I've owned one on my Contender, and recoil was straight back. So the brake would be to reduce that felt recoil. But to be honest, even with a 10" barrel and no scope (read as light as you could make it) the recoil wasn't that bad. Certainly not bad enough to consider a brake. With a longer barrel and a scope, recoil should be even less. Now if you go to 45-70 you're talking a whole nother ball game! As for accuracy, unless you're shooting for competition, or trying to shoot squirrels at 100 yards with a 44, the factory barrel should do fine.
