The best recommendation is to go to a rental range and try them out.
Quoted, for truth.One finer point to make about choosing a defensive handgun:
Make sure that the gun size and shape allows for proper placement and movement of your trigger finger.
First, make sure that the pad (or distal joint, depending on the trigger action you prefer) rests properly on the trigger. For striker or single action pistols, most shooters place the pad of the outermost segment of the index finger on the trigger. For DAO, DA/SA, or DA revolver actions, many shooters prefer to put the distal joint on the trigger.
Second, with your finger properly placed on the trigger, make sure that no other part of your trigger finger is touching the frame of the gun. Make sure this is the case through the entire trigger stroke (or both strokes if using DA/SA gun). If another part of your trigger finger IS touching, you'll likely have a difficult time keeping your sights from moving off the target during the trigger press.
Third, make sure that you can get your trigger finger onto the trigger from the register position (trigger finger off the trigger, on the side of the frame) smoothly and easily. For example, the only way that I can get my index finger from register to the trigger using my S&W 442 backup gun with its stock grip is to shift my hand placement on the grip. My index finger isn't flexible enough to slide directly onto the trigger. Because my grip was constantly changing, speed and accuracy with the 442 was not good until I figured this out.
Fourth, perform these same checks with your non-dominant hand. We fire defensive handguns with both hands, and our hands are not perfect mirror images of each other.
Either change the grip, or choose a different gun if any of these are an issue for you and your hands.
I bought a Taurus G3 in an impulse (Imagine that) and am quite pleased with the gun all the way around and I'm a CZ guy. $300.00 OTD? Hard to beat.Two others that will make some here groan, moan and rail against these options are the Taurus G3 and the Taurus TH9 Compact (external hammer). Despite what some here lost in the past will tell you they are both excellent, reliable firearms with a whole new focus on costumer service and warranty turnaround times if needed. Been that way for a little while now.
I own a G3, that thing is amazing. It ain't your father's Taurus.......
