I seriously doubt there are any real quality differences between a Beretta, a Glock, and a good brand 1911. My doubt is based on the fact that supporters of Beretta claim they are the most reliable and durable, and supporters of Glock claim they are the most reliable and durable, and supporters of 1911's claim they are the most reliable and durable.
So, start this adventure with the assumption that all 3 are equal.
The difference comes down to what FEATURES you want. Single action, double action, double action only? External safeties? Grip angle? De-cocker? Double stack, single stack? Etc. Caliber choice is also a factor.
One of the biggest reasons I chose a Beretta 92FS over other quality choices was because it was THE handgun that fit MY hand the BEST. By fit I mean grip angle, width and length of handle, absence of pinching grip safety, balance, and natural pointing for me. The action was also very smooth, with the slide easy to pull back and chamber a round. I liked the decocker and the external manual safety. Also liked the 180 degree ejection opening along with the ease of manually loading one round at a time.
Since owning 2 FS's, I have nothing but good things to say about them. No jams, always smooth, very accurate.
