Product Description

Featuring a 3.1 inch barrel, the XSeries grip module with a 12 round flush fit magazine and the RomeoZero micro red dot sight, the new P365X RomeoZero brings a new level of performance to your EDC.

These features, along with the signature XSeries flat trigger, all come standard with a ROMEOZero 3 MOA optic installed and ready to go right out of the box. The P365X ROMEOZero maintains the crisp, clean P365 trigger pull that compliments the inherent accuracy improvement of a red dot-equipped pistol.

Perfect Concealed Carry Weapon
Coming from a P250SC, this is exactly what I was looking for; slimmer form factor, FULL GRIP, short barrel length for comfort to conceal, and a red dot thrown on.

almost perfect
i traded in my p365 sas for the p365x with the romeo 0. i definitely like the reflex sight way more than the fiber optic. at first i was excited that the romeo 0 has a rear iron sight built into it because i like having a back up in case something happens with red dot. the first thing i did when i got home was adjusted the red dot to cowitness with the iron sights. but after bringing it to the range, i quickly realized that it does not cowitness at all with the rear iron sight that is on the base. and if i try to use just the irons, it shoots way high and left. im 95% sure that it wasnt my shooting. i see there is a rear iron sight to replace the romeo but its out of stock and has been for a while. they are on ebay for twice the price. lame. but, i still gave it 4 stars because i love the grip, i love the capacity, the trigger is decent for a compact striker fired pistol, and once i zeroed the romeo, it worked fine and was accurate. it's not the best red dot out there and i may eventually upgrade it. but for now it works. i may also get an original p365 slide in case i dont want the romeo, i can quicklt swap the slides out. had the rear iron sight on the romeo 0 cowitnessed with red dot, it wouldve gotten 5 stars. sig should really include the iron sight package with the pistol.

Loved everything but the trigger....
The plain Jane p365 has been my constant carry for over a year now, but because of aging eyes, I decided to pick up the p365X with the RomeoZero red dot. The feel of the full grip is comfortable and very similiar to the original p365 when using a 12 round mag. The RomeoZero is going to take some time before it instinctively comes to the eye, but I'm working on it. My only issue with this pistol is the straight trigger. It seems very gritty and UNsmooth. My solution was to trade frames with my old p365 to get my buttery-smooth trigger back. I'll keep working with the new frame and old slide to try to work out the kinks. Still, I love the red dot.

Carry and Range
Picked um this gem on Memorial Day. Put some rounds down range and fell in love. I am no stranger to SIG but I was also torn because I wanted a full grip (or as full as you can get) with a 3in barrel. So when I saw the release I had to get one. It is a dream good recoil easy to zero in and was able to grab two 15 round mags for her. Great carry gun and fun at the range. Feels a lot better than a standard P365 in my hands. If you want a great carry weapon and also want to have fun at the range this is the one.

My First Sig
I was interested in the P365 SAS, but after trying it out at the range I decided to go with the newest version, the P365X Romeo Zero. Great looking gun. I like the feel, but getting use to the Romeo Zero is a little frustrating. It's not "zeroed in" , so you will have to spend some time at the range trying to get your red dot synced. I'm still not totally satisfied with the accuracy. The two 12 round magazines might as well be renamed 10 round magazines because even with a speed loader they still didn't want the 11th or 12th round entered. I had some issues with the gun trying to feed the first 2 rounds racking the slide after loading. I almost have buyers remorse, but I'm writing these issues off as growing pains of a new gun. I wonder if I would have better accuracy with the red dot off & just using the front sight? Only time, ammo supply & a few more trips to the range will tell. I hope .

Excellent upgrade
Bought this a week ago and it is a nice upgrade from the regular 365. The Romeo zero is easy to sight in and get on target fast!

I had a clear mission that day...find a store with a in-stock P365X RomeoZero! Scored at my local range that I'm a member at. Couldn't believe my luck!!! This is THE conceal carry I wanted and now its mine. The electro optics are factory installed and to me, it just doesn't get any better. The flat trigger is phenomenal! So awesome to shoot this Sig.
