Wow...some serious opinions. One that has not been mentioned in 9mm, Browning Hi-power. I really like mine and am very satisfied with its safety features. Good sights, very accurate, never a jam in over 10 years of serious numbers of rounds. Heck, good enough for the SAS, good enough for me.
Never shot a Sig before but have certainly heard plenty of positives from people I respect. Had a Glock, not a fan. Nothing bad, just uncomfortable to me, plus the lack of a conscious safety (my own made up term), are turn-offs.
Had a Berreta 92 and the Taurus knock-off. Did not like either one. The Taurus would jam on occasion with rapid trigger pulls.
For pure accuracy and reliability, any S&W .357 wheel gun with 4.5" or longer barrell.
