I had a chance to fire the Beretta Pico last weekend. My 5-shot group at 15 feet was about 7 inches and I was shooting low and to the left. I didn't have too little finger on the trigger, wasn't breaking my wrist down, my head wasn't drooping and I wasn't "slapping" the trigger. It just took a lot to pull that trigger. Another shooter fired 7 shots, had an 6-shot group that measured 8" and one that missed the paper, 3 of the shots were low left, 1 shot was way left, one shot was straight under the bullseye by about 4 inches - and this is at 15 feet.
When something like that happens you sort of start questioning yourself, so I shot some of my other guns and did fine. I put together a 3" shot group with my R9 and felt I could say with confidence the Pico has problems - its not me or its not just me shooting tiny handguns.
