About This Firearm
The Sig Sauer P239 is an alloy-framed hammer-fired .357 SIG built for concealed carry. Sig no longer builds it in any chambering, so it's a used buy. Its magazine is a single stack, which is how the gun gets down to 1.2 inches across when the double-stack pistols in this cartridge are wider.
The first shot comes on a double-action pull and the rest on a 4.4 lb single-action break, with a decocker and no manual safety. The frame is hard-coat anodized alloy under a stainless slide, and the grips are polymer. Seven rounds is the flush magazine capacity. The barrel is 3.6 inches turning 1:16, the gun is 6.6 inches long and 5.2 inches tall at 29.5 oz, and the slide has no optic cut.
If you're cross-shopping, the Glock 33 Gen4 is the striker-fired subcompact in the same cartridge, nine rounds at 21.87 oz behind a 3.43-inch barrel, and 7.63 oz lighter to carry all day. The Sig Sauer P229 is the double-stack compact on the same action, 12 rounds at 34.4 oz with a 3.9-inch barrel. The P239 is narrower than both, and it holds two rounds fewer than the Glock and five fewer than the P229.

Strengths & Limitations
- A narrow single stack carries flat against the body, which a double-stack grip of the same height cannot do.
- Nearly thirty ounces in a pistol this small takes the edge off a cartridge that stings in lighter guns.
- Sig built the P239 for almost twenty years, so sights, holsters and springs are still common items.
- Seven rounds flush, where the Glock 33 Gen4 holds nine.
- Out of production, so a buyer takes what the used market has.
- No optic cut and nothing on the slide or frame for a dot, which is a late-1990s design showing its age.

Frequently Asked Questions
Is there an accessory rail for a light?
No. There is no rail under the dust cover, so a light has to be hand-held or carried on the holster.
Can it be carried with the hammer down on a loaded chamber?
Yes. The decocker lowers the hammer without firing and puts the first shot back on the double-action stroke.
What is the twist rate?
A 1:16 right-hand twist.
