5141, Clearly, this is none of my business...but, when I had Perazzi's I always had an extra trigger group. I now have two DT 10s...one of which I have shot the heck out of for 8 years; never a trigger problem. Not one. So, if you think you need an extra trigger group as a back up, I doubt it...just my 2 cents
