Signs of a good carry holster...
I've been around shooting/firearms since the early 1980s.
I've packed & owned a # of different holsters over the years and can provide this input(NOTE; this is for duty/concealed carry rigs only not field/range/military systems)...
A good holster should be able to allow a one-handed re-holster. Author & lethal force instructor Massad Ayoob made that point.
A duty/carry rig should allow quick access to the firearm with either hand quickly. Wounded or weak hand draws are rarely used by citizens but it could be a life saving skill in a critical incident.
A high quality leather, polymer, rubber, nylon, etc. Cheap materials or designs will wear out or fail with regular use. Check the fit & quality. Some "top shops" like Mitch Rosen, Kramer, Milt Sparks, etc only use certain types of leather from certain areas of the steer or cow. Horsehide is better but may cost more.
Kramer also uses Chicago screws over snaps with to me is better. Even Kydex holsters can have minor problems. A small screw came out of my Blade-tech holster for my Ruger GP revolver.
Holsters should protect the front/rear sights & protect the weapon from bumps, shocks, nicks, scuffs, etc. Many gunners like open style holsters but I'd prefer to protect a $900-1200.00 firearm from damage.
Remember the basic rule of engineering; the more parts mean the more things that can break or fail. I'd be hard pressed to carry a level III or IV type duty rig. A solid level II style with a frame mounted ambi safety is good for me in 90-95% of my job uses. Weapon retention is important but you must also consider time if you are drawing a concealed firearm.
Pistol lanyards have value too but that's mostly for marine/boating type places or in PSC/military type environments.
Finally make sure the holster fits or can wear on the belt. Some loops or straps break or wear out. Inspect the design or fit to insure it can work correctly.
Inspect & clean holsters too. Crud, dust, gun oil, etc can collect in gear & holsters.
