When SIG released the P238; a small framed 1911-ish .380ACP, it quickly took the pocket pistol market by storm. People looking for a premium .380 pistol adopted the P238 without many regrets. Then SIG announced a 9MM version dubbed the P938. We were promised a pistol very comparable in size and quality of the P238 and SIG delivered.
The P938 Extreme comes with two magazines; one with a grip extension and one without. Without the extension the 380 and 9mm pistols grip's are the same length. The 9mm's barrel is a bit longer but not by much. A full comparison coming soon.
