One other note about the grip recall in case you aren't aware of the whole story.
The grip is "delrin" which probably makes some sense to a person familiar with the plastics industry, but to a simple guy like me... it just means some kind of plastic. And the earliest grips they made ended up looking right, functioning right and feeling right -HOWEVER- they must have had the mix wrong or they never considered testing it

eek

but the early grips would shatter or crack if the pistol were dropped.
As the grip wholly contains the mainspring (the hammer spring!) a cracked or broken grip directly results in a pistol that absolutely will not fire.
Why do I say all this? Well, as the the 3906 and 3904 were the only full size single stack 9mm 3rd Gens... these models were not produced in high numbers and as was mentioned above, S&W may not find a grip for you.
So I write all this to say that an early recall grip is
100% perfectly fine to own, use and love as long as it isn't cracked or shattered and you don't drop it.
Obviously, it would not be a good idea at all to use a 3rd Gen in a defensive or duty role while it is wearing a recall grip. But the point is that if you own a 3906 to have, shoot and love as a fine pistol and a range toy and a great pistol to pull out of the safe and enjoy... that recall grip is perfectly good to go if it turns out that S&W can't provide a replacement.
Just don't drop the pistol... or use it to hammer nails.
To this end, I have found and purchased early recalled grips from gun shows on occasion, when they are priced low enough to garner my interest. I'm sure that S&W would much rather -NONE- of the grips be floating around or for sale at a gun show... but then again, S&W and myself don't hardly agree about much of
anything these days.
