those look like rogers combat grips to me

i bought a new pair of rogers combats when they first came out in the late 1970s, and wood was available for about 2.5X more than the synthetic ~~~ also the original rogers came with a allen head grip screw

rogers only lasted about a couple years and safariland bought them, and put their large medallion on the right grip ~~~ the hogue combats are almost identical, which were introduced after the safarilands
