I recently picked up a Hellcat OSP. I'd hoped to get one from the factory with a Shield SMSc sight already attached but it looked like that wasn't going to happen. One of my LGSs had the Sig Romeo Zero in stock so after confirming it would match the optic screw holes in the gun, I bought it. The screws are too long and must be shortened, (I used a fine file), or replaced with ones the correct length. The screws must be tight to work right. I've seen a video of someone who didn't bother to use the right length screws and his sight wobbled. Length is critical.

Although I've shot a rental previously, I've only been once to the range so far with mine and most of the shooting was to zero in the sights. One of the reasons I chose the Hellcat was the ability to retain the rear iron sights along with the optic and hence co-witness the two sights. With the bright yellow stock front sight and the blazing bright red dot the sights are very easy to pick up. Once dialed in I was able to shoot good groups at 7 to 15 yards.

I found the Hellcat to be reliable with one failure to lock back after the last round as my only issue. I shot two different brands of range ammo with 115 gr. bullets. I'll test some carry ammo next visit. Overall I am impressed. The gun has good grip characteristics, the sights are bright and redundant. Quick shooting is relatively easy and comparable to any small gun. The fact that it can hold 14 rounds in such a small package is amazing.

The Romeo Zero is quite small and matches the width of the gun. The sight turns off after two minutes if inactive then pops on immediately if moved. Battery life is good for well over a year and advertised as 20,000 hours. Fresh batteries come with a 10 year life span. I've ordered a holster made to accommodate the optic. At .4 ounces it adds little to the weight. My old eyes really take to these small optics. This one allows the exact same sight picture optic on or off.

The Hellcat is certainly worth a look see by anyone thinking of a new carry gun and/or adding an optic to a defensive gun. Here's mine...

I got the OSP Hellcat w/ FDE finish figuring I'd eventually try an optic of some kind, my local smith has probably installed 50 Romeo Zeros on Hellcats for people. I'm personally hoping for a micro green dot of some kind.

I have discovered I require Green to be able to see the dot in bright daylight. Colorblind and red just vanishes.

Same goes for fiber optics
 
usp9, how much did you shorten the screws? I've got a Romeo Zero on order.

The sight comes with two set of screws, one for the P365 and the other set for other sights. The Hellcat manual states that the screw cannot extend from the bottom of the sight plate more than .095 inch, (2.4 mm). I estimate 1 or 2 milimeters need to be removed. I can't say exactly as I didn't measure the overall length prior to filing. It's not much but it must be done or the sight will not work. Took about 15 minutes of trial and error.

The Romeo Zero came in today and I it got it mounted.
It took me a while to figure out that if I put the screw on the wrench and put the wrench in a vise it would be easier to file down. After the vice trick it went really fast. The first I fidled with for about ten minutes, the second one about three minutes.
I had an issue where the windage and elevation didn't work but running them to the stops and back seems to have fixed that. I've got the dot right on the front sight now.
