Use Ion Xe with stock parts except the Critical Ion Trigger instead of stock trigger
Fits finer very well
Much higher rate of fire
Easy to install
The Critical Ion Trigger is the most expensive ($50-$60) on the market for the Ion or Ion XE, but it is 100% worth the price! It fits your fingers veeery well and can take you to a whole different level in paintballing. Plus, it looks really nice and it's easy to install. The only bad thing is that it's the most expensive trigger out there for the Ion, that's the only Con in my opinion.
