Detailed Features 

 
The P938 is a 9mm variant of the P238 .380 platform, scaled up to handle standard pressure and +P 9mm loads. The SAO trigger breaks consistently with the short, crisp pull typical of the 1911 pattern it's derived from. At 17 oz. and 5.9 inches overall it carries in a front pocket or IWB without printing. The X-Ray3 sights use a tritium/fiber front and blacked-out rear for a clean, fast sight picture in all light conditions. Legion Gray Cerakote is corrosion resistant and durable under daily carry.

The P938 Legion draws enthusiastic feedback from buyers who want the SAO trigger feel of a compact 1911-derived pistol in the smallest possible 9mm package. The trigger is consistently praised — the crisp break and short reset feel distinctly better than striker-fired alternatives at the same size.

The X-Ray3 sights are well regarded as one of the better factory sight installations in the compact pistol category. Build quality and fit and finish reflect the Legion-tier positioning and get positive marks.

The main recurring complaints are grip size and capacity. Shooters with larger hands find the P938 grip cramped during extended shooting sessions. The 7+1 capacity is on the low end for a carry 9mm, though most buyers accepted that tradeoff knowingly when choosing the micro-compact format. Some owners report occasional feeding preferences for certain hollow-point loads, which is common for sub-3-inch barreled 9mms.

The price is at the high end for its capacity and size. Most buyers who commit to it are buying specifically for the SAO trigger and Sig build quality, and satisfaction among that group is high. Comparisons to the Kimber Micro 9 and Springfield 911 come up regularly.
