I' ve had a P91 now for about 10 years. Only jammed once out of over 3,000 rounds and that was because of a bad casing. I' ve only shot a Hi Power once and was very impressed. You couldn' t give me a Glock. I' ve shot 4 different ones and never got a 10 round group less than 10" at 20 yards. I' m not an expert by any stretch of the imagination but can consistantly shoot 5" groups at 20 yards with my Ruger. I' ve shot 9mm' s, 40' s, and 45' s but still prefer the 40 best. My Ruger goes everywhere I do and when I carry concealed it' s my Taurus PT938 in .380ACP. Like I said, I' m no expert and only shoot 300 to 500 rounds a year but the P91 feels great, points well, and has been flawless.
