I have never used a gas gun before.  If I want to shoot Federal LE127 00 2 3/4" 1325fps 00 buckshot from this gun as a self defense load.  Can I shoot low base, low power dove loads and these full power buckshot loads with the same  light piston?  Will it hurt the gun?

It will wear it out faster if you use the light piston for the heavy load, because it will be cycled extra-hard.

ED- This guy has another opinion, but I'll run the most restrictive setting any semi will reliably cycle with...

What do you do if you are going to take a class that uses both birdshot and buckshot for training purposes?  It seems silly to have a gun that needs a timeout just because the load is changed.

Most importantly, you will shoot the gun mostly with birdshot and the light piston.  Do you 100% trust the gun to reliably function with the heavy piston and buckshot?  Most people can not afford to shoot a gun too much with buckshot at nearly $1 per round.

The owners manual clearly states that the light piston is for up to 1.5 oz shells.  Most 2 3/4 birdshot and buckshot wheight less than 1.5 oz.

I have the light piston installed in my FN SLP 18".  In fact Ive never installed the heavy piston.  I just run 2 3/4 shells anyway... as I prefer more capacity, not more recoil....  

So, I can shot RELIABLY 2 3/4 birdshot, 00 buckshot and 1 oz rifled slugs as I wish with the light piston.  No need to change the piston.  This is a non issue.
