Hands-On With SIG’s New P320 RXP XCompact and XFull-Size Pistols – SHOT SHOW

Shipping straight from the factory with a SIG ROMEO1PRO red dot and XRAY3 suppressor sights, SIG’s new P320 RXP lineup offers two distinct advantages over combining a pistol and an optic purchased separately.

One: cost savings. SIG stated that the package price is significantly less than the combined MSRPs of the individual components. We haven’t actually seen the final MSRP figures yet, but they were adamant that the combo saves some cash.

Two: form factor. The standard optics-ready guns can’t assume that every customer will choose a SIG optic, so they’re designed with a mounting plate to interface between optic and slide. Different optics have different mounting bolt and pin patterns, so different mounting plates act as adapters to interface between optic and gun.

On the P320 RXP line, which includes a Compact and a Full-Size in both standard P320 and P320 XSeries flavors, a SIG ROMEO1PRO is included, and it’s pre-mounted directly onto the slide. No adapter plate at all. This provides a lower, sleeker, stronger interface.

Complementing the lower mounting height is a set of suppressor-height sights, which co-witness through the optic for backup use should the red dot go down for some reason.

On the range we shot the XCompact, with a 15-round magazine grip length and a shorty slide.

And we also shot the XFull-Size, which fits a 17-round magazine in its grip and has a full-length slide with 4.7-inch barrel.

Both guns felt great in the hand and the trigger, with SIG’s flat trigger blade, was crisp and clean. The X factor definitely ups the P320’s game.

Running a pistol with a MRDS (micro red dot sight) isn’t for everyone, and/or takes training to get quick and proficient with. I was there, but took a hiatus and am now rusty. That said, the dot did its job perfectly fine and the P320 XSeries is a great-shooting gun. If you like shooting a handgun with a dot on it or want to learn, a combo package like the RXP line that both saves money and provides a straightforward, adapter-free mounting solution is a very solid option.

    Seems like no one is interested in this article. Probably enjoying the holiday or keeping up with events in VA. Is Laugo Arms at the Show with their Alien pistol? It is innovative and cool but a bit pricey. That would be a great article! Thanks!

      Meh, this is an old product it’s just now combined with one of their optics.

        The “old product” caused the removal of the rear sight to put the reflex optic on the X series pistols. Thus, if the optic failed you better hope your point shooting was…well…on point. Now you have back up irons already in place. This was the only thing stopping me from buying the original. So, between this and the Cross, it looks like Sig will get a couple of my paychecks this year.

      The Laugo Alien is here. Jeremy shot it. Watch for his post.

    I love p320s … I already have four different versions. But I have no real interest in red dot sights on handguns. I wish Sig would just put their best FO/night sights on their guns instead of making them an add-on accessory. But then they wouldn’t make as much money … no fun in that.

      Me either until my 62 year old eyes could not focus on iron sights. Red dot brought the enjoyment back. No more eyestrain

    On the one hand, I applaud SIG for their success, on the other…my YouTube Channel subscriptions is blosing up with SIG stories…

    My very first handgun was a Glock. I’m a Glock guy.

    The US Military made a huge mistake throwing the handgun contract over to SIG.

    But, I have to hand it to SIG…they are rocking it.

    Kudos guys.

    The distance at which the vast majority of SD handgun uses occur are under 7 yards, usually less. A red dot is a detriment. You need to train, relentlessly, at a distance of 12 feet to put rounds into center mass. A red dot is not going to do any good at that distance.

    Sure, they are fun out at distance, but if you can’t “point shoot” with nothing other than you and your gun…much less a red dot…you are in serious, serious trouble.

    FWIW

      I barely use my sights at close range. I see the front blade and once it is over center the trigger gets squeezed. No, I’m not the most accurate, lol, but I’ll never see my rear sight during an adrenaline dump anyway. With this set-up the irons are still there, and help with alignment and muscle memory. Seems like you can have your cake and eat it too.

        Yep. My old eyes are too crappy for super-elite-operator pistol accurate at distance.
        It’s a personal defense handgun, to be used at typical personal defense ranges.
        Repetitions build muscle memory to get that front sight consistently in front of my eyes. As soon as I’m over the target, smooth but swift trigger presses get the job done.
        I’m still shooting within the area of my palm at 15 yards, so I’m making solid hits where I need ’em.

    Went to the DSCC last weekend and tried every brand of micro red dots on pistols. Apparently, due to my slight astigmatism, they all bloomed like crazy and were therefore, useless to me. I’ll have to stick to the old fashioned way.

    Texican- did you try the Shield RMS? Shield (U.K. company)INVENTED the pistol red dot and sold it to Trijicon 20 years ago! They still make them with their plastic composite lense (ten times more crack resistant than glass) with zero distortion or magnification….I have three of them the SMS the RMS and the RMSw- I can’t believe you saw blooming with them. Their SMS has sold to over 100,000 special forces troops around the world. They just WORK!!!

    1. avatar MrPotatoHead says:

      It’s because of his astigmatism. It doesn’t matter how great the sight, the dot will always be blurry for someone with an astigmatism. You either learn to live with it, or buy a prism sight. Only drawback there is prism sights are bigger and bulkier than a basic RDS.

        Same problem here. Eyes not getting better, aging is a bitch.

    High sig bore axis plus a red dot? Makes me think of snow capped mountains in the spring.
