I have had a chance to shoot both the Titan, Nemesis and PT Honcho. I will give my opinion. I own the Titan and borrowed the Nemesis and Honcho to compare.
If money was no option I would choose the Nemesis. I felt the sight block helped get the front sight back down and returned to zero a little quicker. This in turn helped speed up my times. With that being said I have my Titian running well for me and have found the load that works in my gun.
I was also fortunate to shoot a honcho side by side with the other two. With the new race shop being open and PT putting out their Honcho with the sightblock its a great deal at 3k. Even though this had the sightblock I was faster with my Titan. I don’t think the PT slide to frame fit is as good as the Atlas’s either. I also felt as though the barrel in both Atlas’s were better fit to the gun than the PT’s. The PT’s barrel and sight block felt a little sloppy.
So if I was going into this test blind and had never shot any of these pistols I would’ve chosen the Nemesis. Since money is a variable and I can’t afford it that would’ve left the option of the Honcho and Titan. Of these two I would stick with what I have as I feel the Titan is a better pistol.
