Sort of.
Handguns designed with an eye for LE contract sales generally :
1. Are of a particular size , that translates in real world terms of not larger than a Glock 19 , not smaller than a Glock 19. And porportional weight.
2. Have capability to fit a variety of hand sizes , typically at least interchangable backstraps, sometime entire grip assemblies.
3 . Be in a popular service cal , usually more than one. Typically 9mm and .40 at min, with .357Sig and .45acp following in popularity.
4. Have high visability sights , and usually have factory option for night sights.
5. Have at least pretty good ergonomics for all controls. Be convertable to left hand if not inherently ambidexterous.
6. Have at least reasonably adaquate accuraccy.
7. Be 100% reliable with most ( trying for all ) duty/ defensive ammo.
8. Use a fire control system similar on paper to those already in popular LE usage. Translates to : Fairly long, fairly heavy trigger , for first shot a minimum. Same for rach shot is desired by many LEAgencies , but not all. Most purchasers prefer point and shoot , IF safety is present must be low profile, yet easy to manipulate on purpose , yet not get accidentally bumped.
All the above also would also make the pistol suitable for all around use by Joe and Jane Public , including many self defense roles. Kind of similar to how medimum frame fixed sight .38Special revolvers were very popular with the public as well as LE for several generations.
So then why are all pistols LE Spec ? :
LE AGencies are looking for one size adapts to all. ( Or one family with different bbl lengths ). Civillians buy pistols to fit THEM , and suit their tastes. If somthing fits you , being able to adapt to fit other people who aren't you is low importance. You might prefer ( or be already use to ) a fire control system other than the current flavor of the week for LE Administrators. You might wish a gun size smaller or larger than middle of road to compact-ish. You might wish a cal other than the usual LE Cal.
