This review is on the new Swampfox optic Justice 27mm red dot pistol sight and the Steel City Wolverine combo. Let me start by saying I am an average Joe shooter with a huge interest in firearms. I am always looking for the latest greatest item or something to improve on an older firearm to make me a better shooter. For this review I chose a Glock Gen 3 model 22 in .40 S&W to convert to 9mm. The firearm was purchased some years ago for around $295 and it was a local police trade in. I tossed it in the gun safe, knowing one day I’d do something like this to it.

The Swampfox Justice red dot and Steel City Wolverine slide combo. The slide is in a distressed green pattern and is available for the Glock 19 and 17 Gen 1-3 only. The slide comes with the channel liner already installed and with suppressor height fiber optic sights. They are in the combat configuration (rear sight in front of the optic), the slide is smooth with no machine marks on the outside, except in the area of the optic cutout. The threads on the mounting service were nicely tapped and debured. When mounting the optic it is a nice snug fit. It also comes with 3 sets of screws and Allen keys to mount the optic. The slide has great machining in the front for a good grasp to reload with wet or sweaty hands. It’s texture is just the right combination of aggressiveness, not to be uncomfortable when sharply grasping the gun. It has a lightning cut above the barrel, I assume to reduce weight. I have a concern of dirt or debris getting into it and causing issues in a real world situation.

The optic is clear and crisp, it has an 27mm window and is made out of 7075 aluminum. There is a Liberty version that has a smaller window of 22mm. These are duty rated and have a new and improved hood over their last model. It has a top load battery that takes the CR1632 battery. Not Chad’s favorite. It weighs 1oz without the battery, its height is 1.04”, length 1.78” and width 1.24”. It has the normal parallax free, fog proof and ruby coated lens.

It claims to have a greater battery life and new and improved shake a wake motion sensing illumination. The slide and optic are both for the RMR mounting option. Assembly of the slide is straightforward, just like your normal Glock slide would go together. A Brownells Glock completion kit was used for final assembly.

The initial sight in was done by co-witnessing the dot and the front sight post. Once the impacts were on target I did a ⅓ co-witness, raising the dot above the front sight post to declutter the sight picture. The slide had a few failures to feed, but after some lubrication and some dry fire, it ran flawlessly. The optic is easy to pick up, with some practice, for someone that is new to the red dot game. So far I have fired 350 rounds of 115 grain 9mm with no problems after the initial FTE. I was able to keep all the rounds in the 10 ring at 10 yards. Even with astigmatism the dot was clear with some adjustment of the intensity level.

In my honest opinion I do believe that this will make a great setup for someone that wants to put an optic on their Glock and doesn’t want to have their slide cut, or wants the benefits of having one frame with two different calibers. After my initial testing and what I know of some of the other optic I own from Swampfox, this appears to be a quality red dot. The slide is nice and clean, the battle worn or distressed coloring gives it some character.

Claim to Fame:

A quality optic red dot with a standard RMR footprint, with a cost half the price of others. An improved hood to protect the glass, as well as shake awake technology. It claims to be rated for law enforcement and duty use.

The slide is well textured, nice smooth and rounded corners. Assembly was simple, machining was good.

Target Market:

People who want to get into the red dot game and not have to have their original slide machines. Also those who have a .40 or .357 Sig that want to convert it to 9mm for cost reasons.
