I bought an entire apex and zev trigger kit for my Glock to make it feel how I wanted. I personally don't mind the weigh as much as the spongy feel of the stock trigger. I ended up using the Zev pro kit without the Zev trigger bar. The stock trigger bar gave me a better trigger pull to my finger, heavier but very crisp once you get to the wall. The connector is the biggest part of the improvement, the other parts just smooth out the pull and reduce the pull weight some. Pro connector is less than $20, the other parts start to add up (zev striker, spring kit, firing pin saftey). I have not tried the Timney, so not point of comparison there.
