Description
The Colt Grizzly landed in 2024 as something a little different from the rest of Colt's revolver lineup. Where the Python is the polished showpiece, the Grizzly is the one you actually take outside. Built on the Python-lineage frame in .357 Magnum, it shares the same smooth leaf-spring action and tight tolerances but adds features specifically aimed at shooters who want a capable, weather-resistant revolver they're not afraid to holster up in the field. The stainless steel frame wears a polished finish across most of the gun, with a matte surface on the top rib to kill glare right where you're looking when you're on target.
What Makes the Colt Grizzly Different
The 4.25-inch barrel is a one-piece full-lug design with a ventilated rib and a recessed target crown at the muzzle. Six ports sit near the muzzle, three per side of the barrel rib, venting propellant gases upward to counteract muzzle flip. According to Colt's own testing, the porting costs less than 100 fps compared to an unported Python barrel, so you're not giving much up in velocity but you're getting noticeably better muzzle control on hot Magnum loads. The unfluted cylinder gives the gun its distinctive look and adds some mass to the overall package, which at 41.1 ounces helps soak up recoil too. Sights are a red ramp up front and a fully adjustable rear, with windage and elevation both dialed in at the bench.
Running the Colt Grizzly in the Field
The grip is a Hogue OverMolded rubber unit, and it does exactly what it's supposed to do: keeps the gun planted during recoil and fits naturally in the hand. These grips are fully interchangeable with all Colt Python and Anaconda grips, so if you want to swap in a wood panel set or a different profile down the road, that's an easy upgrade. The Grizzly chambers both .357 Magnum and .38 Special, which is genuinely useful. Running .38s makes for a lighter recoiling practice session, and it opens up the ammo options considerably in a pinch.
The double-action/single-action trigger is the same leaf-spring setup Colt uses across the Python family. It's non-stacking, meaning the resistance stays even through the pull rather than building up right before the break, which is a big deal for accurate double-action shooting. Reviews from experienced revolver folks who've put several hundred rounds through the Grizzly consistently call out how smooth the action feels, sometimes noting it feels even better than a comparable production Python.

Frequently Asked Questions
Can the Colt Grizzly shoot .38 Special, or is it .357 Magnum only?
The Grizzly is chambered for .357 Magnum but fully accommodates .38 Special cartridges as well. Running .38 Special is a great way to get range time with less recoil and usually at a lower cost per round. It also makes the Grizzly a practical choice for anyone who wants flexibility in their ammo selection.
How does the Colt Grizzly relate to the Python? Are they the same gun?
They're closely related but not identical. The Grizzly is built on Colt's Python-lineage frame and uses the same leaf-spring action, but it adds a ported barrel, an unfluted cylinder, and Hogue rubber grips rather than the Python's walnut panels. Think of it as the Python's more utilitarian, field-oriented sibling, designed to be shot hard in real conditions rather than kept as a safe display piece.
What does the barrel porting actually do on the Grizzly?
The six ports near the muzzle, three on each side of the barrel rib, vent propellant gases upward as the bullet exits, which pushes back against muzzle rise during the shot. This is especially noticeable when shooting full-power .357 Magnum loads. According to Colt's testing, the porting costs less than 100 fps in velocity compared to an unported barrel, which is a negligible trade-off for the improved controllability.
Are the Colt Grizzly grips interchangeable with other Colt revolvers?
Yes. The Hogue OverMolded rubber grips on the Grizzly are fully interchangeable with grips made for the Colt Python and Anaconda. That gives you a wide range of aftermarket and custom options if you want to change up the look or feel, from different Hogue profiles to wood panel sets from various makers.
What is the trigger like on the Colt Grizzly?
The Grizzly uses Colt's leaf-spring action, which produces a non-stacking double-action pull, meaning the resistance stays smooth and consistent through the entire trigger stroke rather than stacking up right before the break. It's the same fundamental system used in the Python family and is widely considered one of the best factory DA revolver triggers available. Both single-action and double-action modes are available.
Is the Colt Grizzly a good choice for backcountry or trail carry?
That's exactly what it was designed for. The stainless steel construction handles weather and hard use well, the adjustable sights can be dialed in for your preferred load, and the ported barrel helps manage .357 Magnum recoil in a gun you might need to fire quickly. At just under 9.75 inches overall and 41 ounces, it's a substantial revolver but remains packable in a quality holster for hiking or field use.
