Good choice picking a great firearm! I can't speak to the P-01, but I bought my SP-101 about three months ago. I haven't experienced any issues with the pistol in over 1000 rounds. It fits my hand like a glove, it is well balanced, and it is dangerously accurate- once the trigger is broken in. I have owned pistols costing three times that of the SP-101, and none of them have performed as well.
