What P320 models does this Sig P320 AXG Combat exchange kit from New 21 rd mag x-kit xkit kit fit?
Any P320 with a compatible fire control unit. So the P320’s modular design means you keep your existing fire control module (FCU) and swap in this new slide, grip, and barrel configuration. Also, the 21-round extended magazine fits all P320 models in full-size, carry, and X-series configurations, though it will extend past the grip on compact frames. Therefore, confirm your P320’s FCU compatibility and your intended grip module size before ordering.
What makes the AXG grip module different from standard P320 grips?
Sig P320 AXG Combat exchange kit from New 21 rd mag x-kit xkit Metal construction, not polymer. So the AXG (Alloy XSeries Grip) module is precision-machined from aluminum alloy rather than the standard P320 polymer grip. Also, that gives the pistol noticeably different weight distribution and feel compared to a polymer-framed P320 closer to carrying a classic metal-framed pistol. Therefore, shooters who prefer the feel of a metal frame but want P320 modularity specifically seek out AXG configurations.
Is the threaded barrel suppressor-ready right out of the box?
Sig P320 AXG Combat exchange kit from New 21 rd mag x-kit xkit Yes. So the 4.6 inch barrel is threaded 1/2×28 for suppressor mounting, and the included XRAY3 sights are suppressor-height to clear common suppressor body diameters. Also, a thread protector ships with the barrel for use when not running a suppressor. Therefore, you’re ready for suppressed use immediately without sourcing additional components.
Does the 21-round magazine fit compact P320 models?
Sig P320 AXG Combat exchange kit from New 21 rd mag x-kit xkit It feeds correctly but extends past the grip. So the 21-round extended magazine fits all P320 models including those with XSeries grip modules with or without the magwell installed, but the extended length will result in it sticking out quite a bit with compact or smaller grip modules. Therefore, the 21-round magazine is best suited to full-size or carry-length builds where the extended capacity doesn’t create an awkward profile.
