Went to my local gun shop today, and picked up one of their last Hellcat Pro’s, with the “gear up” package included. $599 for the gun, (4) 17rd and (1) 15rd mags, a mag loader, range bag, and a Crimson Trace red dot. Not a bad deal! FYI- I’m not too crazy about the red dot… I’ve got a Holosun 507k, and a Holosun EPS Carry sitting in my gun safe, and they’re both begging me to install one of them on my new pistol. Y’all liking the new Pro?

For whatever reason, it seems the Hellcat is not discussed much here.

Possibly a good thing as that likely means there arent a ton of issues.
Doesn't mean that much to me to mean that much to you.

The Hellcat (non-Pro) is good to go in my experience. Easy enough to shoot well. The Hellcat Pro is probably just going to be a little easier to shoot and a little harder to carry.

The problem that you may encounter (unless they've changed it in the meantime) is that I don't believe Holosuns will mount directly to the slide of the Hellcat due to having too many indexing lugs (RMSc footprint). I think some ARFCOMMER's have either modified the slide to work with the Holosun footprint or use a plate. I don't run a red dot on my Hellcat, so someone please correct me if my information is wrong or out of date.

I'm running a Holosun HS507K with a C&H Precision plate on my Hellcat Pro.  I torqued the mounting screws to 15 inch pounds and have not had any issues.
I also lock down the brightness setting, and keep an eye out to make sure the screw to the battery tray stays tight.
I also installed an Overwatch Precision FLAX trigger kit and an Apex Tactical extended slide lock lever.  I chose the Overwatch trigger as it uses the stock springs.
Good luck.

I haven’t pulled the CT red dot off of mine yet, to confirm, but I do believe you’re correct, sir. My EPS Carry actually came with a thin adapter plate, that’ll accommodate the rear lugs. If I go with the 507k, I’ll have to get a plate.

How are you liking your OP trigger? I’ve got two of the Tac triggers. One on my Shield Plus, and the other on my M&P Pro, full size. The ones I’ve got have been great! I’ve been thinking about going with another one on this new Hellcat, for the same reason as you.

I've been very pleased.  If I have a complaint, the face of the trigger, where the safety tab is located, has a sharp edge, which can irritate the pad of your trigger finger toward the end of an extended training session.
Recommended.

I have two. One stock and one with the EPS Carry, extended barrel with compensator and TLR 7A light. I'm thinking of putting a new trigger on the later one since the trigger while ok could be better. Several thousand rounds through each without a problem.
