I ordered one today. My biggest complaint on the Hellcat is the trigger, especially compared to the Sig P365 XL. Today I took the Sig with a Romeo 0 and the Hellcat with the Holosun 507K. I hope this improves the trigger and removes the sharp edges that seem to cut into my finger.
I pre zeroed and checked both at home with a laser bore sight. For some reason, that I attribute to the way the trigger is on the Hellcat I was shooting about 2" - 3" to the left. With the Sig I was dead on in a 2" circle target at the same distance for each gun, varying from 5yds to 15 yds. Occasionally I would get one in the 2" circle but the consistency to the left was obvious. I tried varying the windage setting on the Holosun and sometimes I seemed to be closer to center but it wasn't consistent. When I got home I rechecked with the bore sight. Corrected any error I introduced at the range and will have to give it another try, maybe tomorrow. I went through 150 rounds today, so if I go tomorrow I will only take one box. Ammo is still to difficult to get and too expensive. I like to keep 1,000 rounds on hand but that is hard to do these days.
