I love the look of the Hi Power with a commander hammer, but I also like the look of the Glock line. The hammer vs striker question was not even in my mind when I decided to go with Glock over 1911 or Hi Power. It was more a choice of overall ergonomics, price, durability, and capacity. I shoot as well with the Glocks as I do with a 1911. The Hi Power, however, seems to make everyone a marksman. I doubt it's the hammer, however, since few praise the trigger pull of the Browning HP with mag safety still installed, even if it is SA. All down to personal preference in my book.
By the way, did anyone read about the police officer in NY this past summer/fall who stopped a criminal from shooting him by wedging his finger between the hammer and the frame on the criminal's revolver. It apparently broke his finger because the bad guy kept pulling the trigger trying to shoot the police officer, but he never managed to dislodge the officer's finger. If it had been a striker fired semi-auto the officer would probably be dead. Reverse the rolls, and perhaps a striker fired handgun has at least one advantage, as unlikely as the scenario may be. It does happen.
