I would rather have a Speed Six in 3" - but given the choice betwen a GP and a 'Six - all other things being equal - I would always take the 'Six. Nothing wrong with the GP series (or the SP), but I like the weight difference of the Six series and they ain't makin' any more of 'em.
Functionally, IIRC, the two series are the same.
BTW - on the Ruger revolvers, I like the Hogue grips better than the Pachmeyers.
