I've been looking for these parts as well. I purchased an "ESSEX" compact frame from Brownell's, and am told that this frame is the same frame used in the Detonics. My frame came with a hammer, strut and the flat three-fingered 'sear spring', but no grips. Numrich (Gun Parts) shows a part number for the grips, but is out of stock. Triple-K does not list any Detonics parts. Brownell's lists a 'Pachmyer' Signature rubber grip, so I ordered one of those just to-day. Do not know if Brownell's will sell the parts apart from the frame...pete
