Pros:
- Removes more side to side play
- More adjustable than stock
- More comfy contact points
- Cheap.
Cons:
- Ugly (in my humble opinion)
- Difficult to walk
- Still has some slop
It may just be personal opinion, but the stock trigger in some respects felt better to me than the vapor trigger. I can honestly say this is the only vapor product I really don't like that much. It's just a strange feeling trigger... there's not much more to be said.
Conclusion:
An essentially pointless upgrade. If you want to get a better trigger, get a new frame.
