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.
