Hello, Ed45. I am neither a Defender expert nor a fan as I don't particularly care for short pistols, but I have shot several.
All had the Novak type sights you mentioned.
All of these pistol's sights were well-regulated out of the box and all were dependable although most of my shooting with them was only with ball ammo.
The sights gave a good sight picture and recoil was not nearly so "bad" as originally expected.
Fit and finish was fine on these guns.
That's about the best I can do from personal experience.
Best.
