It might have been bad luck, as its only one data point, but seeing how durable the TM pistons are, I would not recommend that upgrade.

Also, you might want to look at the PDI piston head and cylinder, they are almost always in stock and cheaper:

If you order from PDI, you might as well get your inner barrel there. I have the stainless 6.05 in one of my G18c and its amazing. Prices are similar, but again, they are easier to obtain. I also have a MP7 length PDI Raven inner barrel that I used for a while in a G18c and it worked surprisingly well for such a cheap barrel.

I'm assuming theres no compatibility issues with the stock/nine ball pistons + cylinder head and the PDI cylinder + piston head?
