Target Audience 

The P938 Legion works well for experienced carry shooters who are already comfortable with SAO handguns, and for new owners who want a primary concealed carry gun and are willing to train with the SAO system. 
 

Usage Scenarios 

The main use case is concealed carry -- the combination of SAO trigger, small size, and quality sights makes it a capable defensive pistol. It also holds up well at the range for skills maintenance and is popular among sport shooters who want a compact pistol with a competitive-quality trigger.

Discussion around the P938 Legion tends to focus on a few consistent themes.

Build quality gets high marks. The aluminum frame and stainless steel slide feel solid, and the Legion Gray Cerakote finish looks professional. Shooters who handle it in-store frequently comment that it does not feel like a budget gun.

Accuracy is well-regarded for the size. The SAO trigger is described as crisp and light, which contributes to better shot placement compared to striker-fired micro-compacts. The XRAY3 sights draw positive comments for low-light performance.

Size and concealability are the main selling points in user discussions. The 17 oz. weight and 5.9-inch overall length make it genuinely easy to carry, and most owners report it disappears under normal clothing without much effort.

Recoil comes up regularly. Some shooters note that the compact frame transfers more felt recoil than full-size 9mms, while others find it manageable with practice. The consensus is that it takes more training to shoot well than a larger gun.

The 7+1 capacity generates debate. Owners who prioritize capacity sometimes wish for more rounds, while others consider it adequate for a carry gun of this size.

Pricing draws comment -- the Legion trim level costs more than comparable micro-compacts, which some buyers see as justified given the fit and finish, and others see as a stretch.

Reliability is generally reported as good, though discussions always include individual accounts of specific ammunition preferences or occasional break-in issues.

Aftermarket support -- grips, holsters, and accessories -- gets positive mentions from the enthusiast segment.
