My JM PC627 V-Comp now sports Ahrends square conversion finger groove cocobolo stocks like the upper 625MG in my photo. It is my heaviest revolver - and the squared back I find as indispensible in supporting the muzzle heavy revolver as I do the finger grooves. The 625JM is on the edge - it feels better tor most plinking with similar grips - but the included JM stock is second, in my book - and does make for a faster, no-grope/fidget, 'grab'. Of course, as I would have to buy more Ahrends stocks, $60 + $6 s/h, and those JMs came on the 625JM, I'll just have to get by, LOL!
