Geissele SD-3G is amazing!
After doing some research on aftermarket triggers, I quickly saw that Geissele was the brand to go with. I then had to decide on which one. I was impressed with the videos of the SD-3G and at how quick the reset is. The one thing that made me hold off was seeing in several posts/reviews that some people would have accidental bumpfires because the reset was so quick. I didn't want something that light so I first installed a SD-C.
The SD-C is a great trigger. The flat trigger is very comfortable. I really liked the way the two stage triggers are setup, but I just wish that the reset was quicker. Also, I think that if I really wanted a two stage, I would have preferred the SD-E. If I was always wearing gloves while shooting to where I didn't have as much feel in my trigger finger, I think the SD-C is a little safer in that situation.
I went ahead and ordered the SD-3G (which I should've done at first). I installed the 3G with the quickness having already done the SD-C. I grabbed a magazine and stepped outside to try it out. I didn't want to try and be extra careful with my trigger pull so that I could really see how sensitive this trigger was. I quickly slung up the gun and popped off one round... no accidental bumpfires or anything. The 3.5lb trigger pull feels lighter than pulling through just the second stage of the SD-C. Once you start pulling back on the 3G, it just breaks very smoothly. The follow ups with this trigger is where this trigger takes the cake. I never had an accidental discharge from the quick reset. If I wanted to fire 3 shots quickly, 3 shots is what I got.
I really think that these people getting accidental bumpfires and whatnot either do not know how to properly shoulder their weapon or have some crazy uncontrollable muscle spasms in their fingers. I am extremely happy with this trigger and wouldn't hesitate to recommend it to anyone.
