Description
There aren't many carry guns that turn heads at the counter the way this one does. The SIG Sauer P938 Rainbow Titanium takes the proven micro-compact P938 platform and dresses it in a high-polish Rainbow Titanium PVD finish that shifts color as it catches the light. Underneath the flash is the same 1911-inspired design that made the P938 a favorite among folks who want a real single action trigger in a pistol small enough to disappear in a waistband holster. The crisp, short pull is a big part of why people shoot these little guns better than most pocket-sized 9mms.
Built Like a Shrunken 1911, Sized for Everyday Carry
The P938 Rainbow runs a 3-inch barrel with an overall length of 5.9 inches, a height of 3.9 inches, and a width right around an inch, so it rides flat and stays out of the way. The aluminum alloy frame keeps unloaded weight down to about 18.6 ounces, and it wears a black hard-coat anodized finish that shrugs off holster wear. SIG rounded and beveled the slide edges too, so the draw stays smooth and snag-free even from deep concealment. The ambidextrous thumb safety works naturally for left- and right-handed carry, and the hammer-fired single action setup will feel like home to anyone who grew up on 1911s.
Rainbow Titanium P938 Features That Earn Their Keep
The SIGLITE night sights are a genuine standout at this size. Plenty of micro pistols come with sights that are little more than an afterthought, but these tritium three-dot sights give you a usable sight picture in low light, which matters more than anything else on a defensive gun. Hogue G10 grip panels round out the package, giving your hand real texture to hang onto when running fast strings with a two-finger grip. Each pistol ships with one 7-round steel magazine for a 7+1 total capacity, and it's backed by SIG's Infinite Guarantee lifetime warranty. Good-looking, sure, but this is a working carry gun first.

Frequently Asked Questions
Is the P938 Rainbow Titanium a good concealed carry gun or just a showpiece?
It's both. Under the flashy PVD slide is the same proven P938 platform folks have carried for years, with a lightweight alloy frame, snag-free beveled slide edges, and tritium night sights. At 5.9 inches long and about 18.6 ounces unloaded, it conceals as well as almost anything in 9mm.
Does the SIG P938 have to be carried cocked and locked?
Yes, like a 1911, the P938 is a single action design meant to be carried with the hammer cocked and the manual safety engaged. That's how the platform was designed to run, and it's what gives you that crisp, short trigger pull. This model has an ambidextrous safety, so it works the same for lefties.
How many magazines come with the P938 Rainbow Titanium, and do standard P938 mags fit?
This model ships with one 7-round steel magazine for a 7+1 total capacity. It accepts standard P938 magazines, so picking up spares or extended options is easy since the platform has been around for years.
Will the Rainbow Titanium finish hold up to holster wear?
The rainbow coloring is a Titanium PVD coating, which is a hard, durable finish that resists wear and corrosion far better than paint or standard bluing. The frame is separately protected with black hard-coat anodizing. Like any finish it isn't indestructible, but PVD is one of the tougher treatments out there for a daily carry gun.
