Many things about a handgun are subjective ie does it fit your hand ? Are the sights visible & quick to aquire ? Is the trigger usable or can you pull a truck out a ditch with it ? Is it accurate enough for the job at hand ? Lastly is it chambered in a round that you can shoot well ?
I have 2 Glocks a 30S & a 17 . Both have fitted KKM barrels , NS & Talon grips . I look at them like an AK , they'll take more abuse than you can dream of & they still work every time . Besides if one of my guns has to get a PD property stamp , let it be a plastic one . Yes they are ugly , some say " as ergonomic as a brick " , bottom line they're about as dependable as a mechanical device can be .
