What makes the P320 XFIVE completely, totally different from all other polymer-framed, striker-fired handguns is its tungsten-infused grip module. The tungsten brings the pistol’s dry weight over 43 ounces which is on-par with many steel-framed handguns. Additionally, because the grip is polymer-based, it still has the flex and give of a standard polymer pistol.
SIG says the combination reduces muzzle rise by 50 percent over the all-polymer models. They’ve also added an improved, skeletonized trigger system with a 30 percent lighter pull weight. The P320 series is already well-regarded for its trigger feel, but it is still a duty trigger with a heavier pull than most competition pistols. Another competition-oriented feature is 14-pound recoil assembly that can be replaced with an included 12-pound spring for use with light target ammo.
The full-size pistol is chambered for 9mm Luger and has a 5-inch barrel and lightened slide and comes standard with three 17-round magazines. Because it is a competition handgun it comes with a Dawson Precision fiber-optic front sight and black target rear sights. The rear sight assembly can be removed and replaced with a SIG Romeo mini red-dot sight.
Besides the weight, the grip has a couple of features that make it stand out from the full-size P320. It has an oversized, extended beavertail and a more contoured grip with an undercut trigger guard. It also has an oversized, flared magwell paired with magazines with enlarged magazine base pads by the Henning Group.
Like other Legion pistols it has a dark grey PVD finish and otherwise sports the same features as other P320 pistols including reversible magazine safety, ambidextrous slide levers, and forward and rear slide serrations.
If all that’s not enough, SIG is offering even more exotic Pro series slide upgrades that have even more lightening cuts, X-Ray high visibility day and night sights, and – of course – a cutout for mini red dot sights.
These Pro slides run $399 and have a bead-blasted stainless finish with black highlights for a two-tone look. They don’t include the barrel and recoil assembly but they are available right now in full size, compact and sub-compact. They may be a little on the expensive side but hopefully SIG sales and other resellers will help take the edge off the MSRP.
