A) The grips pictured are Altamonts.
B) No, they will NOT help absorb recoil, unfortunately. Though they do cover the back strap of the gun, they do not really offer any more surface area over which recoil can be dissipated. Plus, they are solid, with no "give" like a rubber grip. Regrettable, as they certainly look a lot better than rubber grips.
"Felt recoil" is a subjective thing. Whether any particular grip is more comfortable in use than another is something that only the individual user can decide. But, if one is looking for substantial recoil reduction - if the existing recoil is deemed too harsh - these won't do it.
