Piston heads for the TM meu and G17

[GothicGhost]

Hi all.

 

I need new piston heads for my TM 1911 meu and glock 17.

Not sure if the piston heads are the same for the m1911,meu and glock 17?

 

I was looking at this that and it says it's for m1911 and g17.

But this one is the same product but does say it's for the g17.

Thanks for any help.
