About This Firearm

The Sig Sauer P229 is an alloy-framed hammer-fired .357 SIG built for plainclothes and off-duty carry. Sig's current P229 pages list 9mm only, so this chambering is a used buy. It weighs 34.4 oz in a pistol 7.1 inches long, which keeps a bottlenecked high-pressure cartridge mild to shoot.

The first shot comes on a double-action pull, every shot after it on a 4.4 lb single-action break, and a decocker lowers the hammer with no manual safety to work. The slide is stainless in a Nitron finish over a hard-coat anodized alloy frame, and the grips are Sig's one-piece E2 polymer. The barrel is 3.9 inches of carbon steel turning 1:16, the gun is 1.5 inches across, the magazine holds 12 rounds, and the slide has no optic cut.

If you're cross-shopping, the Glock 32 Gen4 is the striker-fired compact in the same cartridge, 13 rounds behind a 4.02-inch barrel at 24.34 oz, which is 10.06 oz less on a belt. The Sig Sauer P226 is the full-size pistol on this same action, with the same decocker and the same single-action pull. The P229's extra weight over the Glock holds the muzzle down, and it is 1.5 inches wide to carry.

Best For

GOOD
Concealed Carry
A 7.1-inch pistol hides under a jacket or an untucked shirt where a full-size duty gun prints, and a decocked hammer means the draw has nothing to switch off.
GOOD
Range/Target
Thirty-four ounces of alloy and steel settle a cartridge that is sharp in lighter guns, and the single-action break is 4.4 lb.
FAIR
Duty
Agencies that issued this cartridge trained on these controls and this trigger, but a pistol out of production has no factory support behind it.

Strengths & Limitations

Strengths
  • Carrying with the hammer down on a loaded chamber is the designed condition, so the first shot needs no safety wiped off.
  • A Nitron stainless slide over anodized alloy is a corrosion pairing built for a holster worn every day.
  • Twelve rounds in a compact frame is competitive capacity for a hammer-fired pistol in this cartridge.
Limitations
  • No optic cut in the slide, so a dot means paying a shop to mill it.
  • At 34.4 oz and 1.5 inches wide, daily carry needs a stiff belt and a holster that can hold it.
  • The long first pull and the short ones after it take range time to shoot to one standard.

Frequently Asked Questions

Where was the P229 made?

In Exeter, New Hampshire. Sig describes the P229 as the first pistol it manufactured there.

What is the twist rate?

A 1:16 right-hand twist.

What does the decocker do?

It lowers the hammer without firing a shot, which puts the next trigger pull back on the long double-action stroke.
