Home / Guides / Best Holster for a SIG P938: Single-Action Pocket and IWB Carry
The P938 is a single-action 9mm the size of a .380, carried cocked and locked like a 1911. That combination means the holster has two jobs: cover the trigger and protect the thumb safety.
Like a 1911, the P938 is designed to be carried condition one: chamber loaded, hammer cocked, thumb safety engaged. The holster must support that configuration, which means:
| Model | Caliber | Class | Holster interchange |
|---|---|---|---|
| P938 | 9mm | Micro single action | P938-specific |
| P238 | .380 ACP | Micro single action | P238-specific |
Same design language, different slide dimensions. They do not share holsters despite looking nearly identical in photos.
| Position | Works | Notes |
|---|---|---|
| Yes | Needs rigid pocket holster with full trigger coverage and a safety-protecting shape | |
| Appendix IWB | Yes, very well | Small enough to disappear; verify the safety does not contact your body |
| Ankle | Yes | Light enough; backup role |
Pocket carry is where the P938 shines, but it is also where the safety is most vulnerable to being nudged. Use a pocket holster with a body that shields the safety lever from the pocket interior.
A single-action micro pistol requires a consistent, trained safety manipulation on the draw. This is the trade for a better trigger than a double-action .380. It is a good trade for people who train it, and a bad one for people who do not. Dry fire until the safety sweep is automatic.
Yes, in a rigid pocket holster that covers the trigger guard fully and shields the thumb safety. Pocket carry is one of the P938's strongest roles.
No. The slides are different dimensions despite the visual similarity. Use a P938-specific holster.
Yes, that is the intended carry condition for a single-action pistol. It requires a holster with full trigger guard coverage and a body that protects the thumb safety.
A P938-specific holster with thumb safety protection — a rigid pocket holster for pocket carry, or a compact IWB holster for appendix. Retention should be snug and consistent.
Not a special type, but one molded for the P938 that shields the safety lever. The small size means the safety sits close to your body, so check that it is not being nudged.
