Glock parts numbers prior to the Gen 5 models was not the same for the .40 and 9mm firing pins.

9mm was GLO49 and .40 was GLO4270.

The firing pin nose on the 40s is slightly longer than the 9's.  Otherwise, they're structurally the same.  I wouldn't put a 40 in a 9 for anything other than the emergency "get me through the end of this match", as you may have a pierced primer or two.  

 

The way to tell on current production pins for the Gen 1/2/3/4's is counting rings on the forward portion of the firing pin:  there's one for 9, two for .40.  Older pins were unmarked on the 9's and had ".40" stamped on the firing pin lug.  Like JBP55 said, 5's are a completely different animal.

 

As a side note, just about everybody who builds aftermarket firing pins uses the 9mm dimensions and folks put those dimensioned Lightning Strikes, Jagers, Zevs, et. al. in a ton of 40's.
