Herrett's still has a custom shop, but the last couple of sets I got from them were somewhat disappointing. Their Thumbrest Trooper is just like the Sanderson design. Adamovitch (?) makes the Skeeter-style Ropers, and makes them well. There's a thread here on them. There's some nice stocks out there, but they're not cheap.

The LAPD style of "combat" grips evolved from the experiments of Walter Stark of the LAPD pistol team in the mid-'30s. Remember, this was NRA Bullseye shooting.

The "bobbed" frame, which gets Farrant a lot of grief from today's "collectors", came about in the early '50s, courtesy of Jo Blackford, another team shooter. Fuzzy Farrant, John Hurst and Guy Hogue evolved the "combat' variations in the late '50s/early '60s.

FWIW, Farrant was the 4th shooter ever to achieve a 2600, in'50, the epitome for a bullseye shooter. Hurst was 9th in '53.

Good shooting!

I've watched the first season of "Adam-12" on DVD. Malloy's K-38 wears a nice pair of what appear to be Farrant grips.

Homie- you know your stuff! As far as John Hurst's shooting career goes, he went on to break 2650 (with revolvers) and shot in the 1960 Rome Olympics. He was the first Officer to shoot a perfect 400 on the LAPD bonus shoot, also. I can remember Farrant and Hurst grips in the showcase of the Revolver Club, for about $28.00 (new). The stocks for the "notched" frame weren't allowed to be sold at the Academy, though, because Officers were not supposed to alter the city-issued guns. Most coppers did anyway, and did other neat stuff, like putting on heavy barrels, etc. It truly was a different time.
