My P-01 is for emergencies. My feeling is that in an emergency, particularly in a low light situation, I'll be lucky to see the front sight in my peripheral vision...quick acquisition will be crucial to my ability to get on target ASAP. So, I have XS Big Dot sights, and am very happy with them...superb in low light! Initially, the front sight was too short...they send a replacement for $0, Would I recommend them for bullseye shooting? No, but the P-01 is a self - defense weapon for me, not a range/competition gun.
