TFB Review: SIG Sauer P320 RXP XCompact

    In the past few years, there have been a number of great little concealed carry options hitting the market. Whether it’s the Glock 43X, 19X or Springfield Armory¬†Hellcat, there are plenty of new options available. Recently, SIG announced their red dot equipped X-Series called the RXP. The new RXP pistol has a few different changes from the previous versions of the XCompacts and they may be small changes but make a big difference in everyday use. Let’s dive into the new SIG RXP XCompact and what it has to offer.


    Over the last couple of months, I’ve carried the SIG P320 RXP XCompact and wondered if the changes were worth swapping out my standard XCompact for the new model. Just like the original XCompact, the new RXP has a 3.6″ barrel and weighs 25.6 ounces unloaded. The New RXP comes with the X-Series flat trigger just like the previous models which is a nice change from the standard P320 trigger. Probably the biggest change between the older XCompacts compared to the new RXP is the undated optics cut and rear sight assembly. The SIG Romeo 01 PRO that comes attached is a 6MOA red dot that has a large field of view that’s extremely easy to pick up.

    The older XCompact had a slide cut for an optic as well, but the overall set up was a bit different. The previous generation had the rear sight built into the optics plate which worked but the mounting screws locked into the plate next to the rear sights. Having the mounting plate next to the sight made the optics plate secure but added to the overall thickness of the rear sight. Thankfully, the new model has separated the rear sight and optics cut so it eliminates the problem of losing a rear sight and the issue of overall thickness. The new RXP XCompact has suppressor high XRAY3 night sights with smaller blacked rears with tritium inserts and a large front dot. MSRP on the new RXP XCompact is set at $999.99 but the street price seems to have settled down around $899.99.

    Range Time

    Now I will be honest and say, I have always had a hard time transitioning over to an optic on a handgun. I have no doubt there are benefits for longer distances and shooting more accurately with a dot but I haunt spent the time training with an optic on my pistol. Over the years, I have had a couple of Glocks with Trijicon RMRs but never really enjoyed shooting them like I have with iron sights.

    While taking the SIG Sauer RXP XCompact out, I found it to be a great gun to learn the basics skills of shooting a handgun with a red dot. The wider field of view and 6MOA red dot makes it very easy to pick up without having to do the weird shuffle while you search for the red dot. The suppressor height sights naturally bring your eye up on target to meet the red dot as well.

    Trigger and Accuracy

    During my time with the RXP XCompact, I shot roughly 1,200 rounds through the gun and it ran 100% even when putting steel cased Wolf 9mm and Blazer aluminium cased 115gr ammo. For the majority of my testing, I used a mixture of SIG Sauer 115gr ball ammo and Blazer Brass 115gr and both ran flawlessly through the gun. The flat X-Series trigger that comes standard with the gun is a nice upgrade from the standard curve trigger. The trigger had a short take up with a crisp wall before breaking around 5.5 lbs followed by a quick positive reset.

    Accuracy is fairly impressive with only a 3.6″ barrel on the RXP XCompact. At 10 yards I shot some slow controlled groups and my average group size from 5 groups varied from .75-1″ with standard range ammo. Given its size and overall use, the RXP XCompact is impressively accurate.¬†The XRAY3 sights are quick in close quarters shooting and make fast shots fairly easy.


    One of the biggest benefits of having a P320 is the ability to change frames, slides and make a custom gun to your exact needs. I shot the RXP XCompact entirely stock for testing but once I finished up, I decided to use the slide for my PMM Compensated P320 Range handgun. Having a dual-port compensator along with a red dot and suppressor height sights is a definite plus. With Parker Mountain Machine and Agency Arms both coming out with barrel/compensator combos for sale, it’s a great way to have a high-end range gun without spending a few thousand dollars like you would with many other high-end handguns. It’s an added benefit if you’re on the fence about having a compact handgun if you’re looking to have a range option as well.

    Overall Thoughts

    I wasn’t sure about buying the new RXP since I already bought the XCompact a couple years ago, but after spending a good amount of range time with it, I’m rather pleased with the changes they made in the new RXP model. I think this handgun would be a great option for anyone who wants to carry an optic on their concealed carry handgun or someone who’s looking for a range ready project gun for one of the aftermarket compensators that are growing in popularity. It may not be a project everyone wants to do but it’s really a great way to make a handgun truly yours.
