Which Speed 6? Barrel length etc? I think the GP is a better gun in some respects - grips etc - I own a 6 inch SS version and an SP101. But, I think the Speed 6's are neat and possibly lighter weight due to the lack of a full length shroud and they had adjustable sights.
If they made it and I'm not sure they did - a 3" Speed 6 with adjustable sights is something I would jump on. Kinda like a Smith Model 60 you could actually shoot the hell out of and not worry.
