Kaya introduces a head-to-head comparison between the Glock 43X and the Sig Sauer P365, focusing on which platform might suit different concealed carry needs. He notes that both are extremely popular and that the P365 line has been influential in changing the concealed carry market. The Glock 43X is highlighted as a slim, under-one-inch-wide pistol that is easy to conceal but limited by its single-stack magazine. The standard Glock 43 holds six rounds, while the 43X extends the grip for a 10-round capacity. Kaya emphasizes that these are among the most common concealed carry choices and sets up the video as a practical comparison rather than a brand promotion.
Kaya explains how Shield Arms magazines address the Glock 43 and 43X capacity limitations by offering higher-capacity metal magazines. In his setup, the Glock 43X runs a 15-round Shield Arms magazine, and the Glock 43 version can reach nine rounds. He then shifts to the Sig P365 X-Macro, describing how the original X-Macro had an integrated compensator and how the lineup now includes the X-Macro Comp and a standard X-Macro configuration. The X-Macro’s 17-round magazine is compared to full-size 9mm pistols, which Kaya considers a major advantage. He stresses the P365’s modular design, where the fire control unit is the serialized component and can be moved between different slides, barrels, and frames, including a P365 Flux Defense chassis for an alternative configuration.
The discussion broadens to related models in each family. Kaya shows the Glock 48, describing it as essentially a Glock 43X with a longer barrel and slide while sharing the same frame and factory 10-round capacity, with the option to use 15-round Shield Arms magazines. On the Sig side, he brings out the P365 Spectre Comp, an XL-size P365 variant with an integrated compensator, upgraded trigger, and a 12-round flush-fit magazine. He notes that it sits on the higher end of the P365 lineup. Kaya also references the standard P365 as a very compact option suited to shooters with smaller hands, contrasting it with the larger X-Macro and XL-sized configurations.
Kaya sets aside his battle belt to focus on concealed carry use, running an appendix holster with the P365 X-Macro. He demonstrates a simple draw sequence: clearing the cover garment with the support hand, establishing a solid grip, presenting the pistol, and firing controlled strings. On the range, he notes that the X-Macro’s grip size allows a full firing grip, unlike the smaller Glock 43 or standard P365 where only two fingers fit on the grip. For him, the larger grip improves control, shot placement, malfunction clearance, and reloads. He comments that the recoil impulse is manageable, the slim grip feels good in the hand, and the trigger is notably good for a concealed carry pistol, which helps explain the P365’s strong presence in the concealed carry market.
Switching to the Glock 43X in a separate holster, Kaya repeats the same basic concealed carry drills. He quickly runs through the factory 10-round magazine and remarks how fast it empties compared to the 17-round P365 X-Macro. The difference in capacity, which seems abstract at the bench, becomes very noticeable during live fire. He observes that the 43X has a snappier recoil impulse than the X-Macro. To address capacity, he introduces a 15-round Shield Arms metal magazine for the Glock 43X, describing it as a way to bring the Glock closer to the Sig’s on-board round count. He emphasizes that capacity becomes a practical factor once shooting starts, not just a specification on paper.
Kaya discusses concerns often raised about using metal Shield Arms magazines with Glock’s factory polymer magazine catch. Critics argue that the metal magazine body can wear down the polymer catch over time. He points out the sharp engagement surfaces on the Shield Arms magazine where it locks into the frame and acknowledges the long-standing advice to replace the Glock mag catch with a metal one. Kaya then relays what he was told about FBI testing, stating that the agency reportedly ran thousands of reloads with Shield Arms magazines and standard Glock magazine catches without experiencing failures or excessive wear. He notes that, based on that information and the FBI’s reputation for firearms testing, he is comfortable relying on the combination for extended use.
After more shooting, Kaya reflects on how capacity and ergonomics affect performance. He again notes that the P365 X-Macro’s 17-round magazines allow more shooting between reloads, while the Glock 43X’s 10-round factory magazines run dry quickly. He addresses the common argument that capacity is unimportant if a shooter has good training and shot placement. Kaya disagrees, stating that capacity is extremely important and that real-world incidents show individuals continuing to fight after taking multiple well-placed hits. He clarifies that his experience comes from watching documented shooting footage rather than personal gunfights, but he believes those examples support carrying more rounds when possible. The session reinforces his view that both training and capacity matter in a defensive handgun.
In closing, Kaya compares the Glock 43X and Sig P365 platforms as concealed carry choices. He notes that both companies produce reliable firearms and that he has had good results with P365 pistols and Sig rifles, while also having long-term experience carrying Glocks. He reiterates that the video is not sponsored by either manufacturer and was made to address ongoing interest in concealed carry setups. The P365 X-Macro stands out for its 17-round capacity and modular fire control unit, which can be moved into different frames and configurations. The Glock 43X offers a slim profile and familiar Glock ergonomics, with aftermarket Shield Arms magazines helping to close the capacity gap. Kaya frames the decision as dependent on individual hand size, preferred grip, and how much capacity a carrier wants to prioritize.
