I shoot the G19 professionally, and have scored Distiguished Expert with it. I carry a CZ PO1 off duty, and would not own a Glock. Contrary to many expressed opinions, I have witnessed Glocks fail many times, and break. I have had them fail on me during qualification, as well. My CZ has had a few FTF with my own, over-long
first generation handloads, never factory ammo, and has not failed me. And I may not shoot once a week, but usually twice a month or so, Logos.
The Glock "Safe Action" trigger is anything but - a light trigger pull from the untrained or partially trained finger wandering unaware inside the trigger guard causes a "boom" sound...kind of like that DEA agent found out in that famous movie clip. The New York and New York + trigger enhancements can stiffen the Glock trigger to help avoid that, but make every shot stiffer.
The long DA pull of a revolver, or first shot of a DA/SA pistol is what many people used to demonstrate safety, needing the deliberate double action pull to fire. Some Depts and private security agencies issue DA only sidearms for liability purposes, to avoid negligent discharge lawsuits from light SA pulls. Does it happen? Yes, not to the extent the boogymen make it out to be. In the end, I believe the Glock to be, (wait, Glockophiles, it ain't as bad as you think), to be an experts only sidearm, those who wish to spend thousands of rounds absolutely mastering the trigger usage. It is a well made, reliable product, with all the ergonomics of a poorly cast brick.
I do NOT reccomend any small, light wheel gun, as with decent defensive ammo, the recoil may scare or intimidate ANY novice shooter. Someone who is afraid of thier sidearm will not shoot it, and then will never become proficient with it. Let her try several firearms at a rental range, and see what fits her. I went through many sidearms for my wife before she decided she liked mine. Now she carries a CZ2075 RAMI, and loves it.
