Takes some tweaking and possibly some modification to your trigger assembly
I purchased the TechT Hairpin trigger kit for about $20 from TechT's eBay store.
This product actually works by shortening the travel of the trigger and/or sear. This leads to faster rates of fire and faster hammer resets.
After a little bit of tweaking and some modification to the safety "knob" this thing works great!
I had to slightly file down the safety "knob" in order to allow smooth movement of the trigger. This was required since the pins I selected caused the trigger to rest slightly higher - interfering with the safety. Safety is still fully functional and works great.
I have the double trigger on the semi-auto frame. The double trigger allows for even faster rates of fire when coupled with this Hairpin kit from TechT.
I'll describe the stock trigger and then the modified trigger (with the hairpin kit and double trigger kit)
Long, 'mushy', extra unwanted 'overpul' (after the marker fires the trigger can still move backwards), slightly wobbly.
Double Trigger with TechT Hairpin Kit:
Very Short, snappy, solid, precise, no extra 'overpull', little side-to-side play.
I would recommend this product to anyone who wants an affordable trigger upgrade (around $40 for trigger and hairpin kit) who doesn't want to spend $100+ on the e-grip or who doesn't like the 'throwing action' of the response trigger. Definately a worthwhile investment.
