I've put approx 300 rds.(factory & my own loads) through my P250c 9mm with no problems. It does not like low powered loads(my own), which resulted in several stovepipes. My fault, not the gun's. Accuracy and ergonomics are superior to my old favorite Glock 23. While I prefer the .40 over the 9mm, I'm really pleased with the shootability of the Sig. Loaded with Federal HST's, I wouldn't hesitate to make this my prime defense gun. From an engineering view, it's just too cool. Here's hoping for a long and happy relationship.
