Second-hand, but trustworthy experience with just one. A friend, retired gunshop owner and rabid shooter, got one of the earlier ones from his son, who now runs the shop. After 70-80 rounds the first day out, he was ready to trade it for fishing weights - 10" groups at 25 yds, and several stovepipes. He fired his remaining ammo, and one of the other guys asked to fire it. After 20-30 rounds, something (a machined chip, high spot, tight spot - who knows??) settled in or fell out, and the gun choked down to 3" groups, and never failed to cycle thereafter. His collection runs well over 300 guns, and he has experience with many more, and said he had never had a gun change so radically on it's first run. With a nearly bottomless stock of choices, he now considers it his favorite compact.
