July brings high temperatures, intense humidity, and a shift to a much lighter wardrobe. While shorts and t-shirts make the summer heat bearable, they present a major challenge for everyday carry (EDC) enthusiasts. Heavy setups imprint easily through thin fabrics, and constant exposure to sweat introduces moisture and salt directly to your defensive tool.
If your primary carry gun is a Smith & Wesson M&P series pistol, summer is the perfect time for a quick seasonal tune-up. By streamlining its external profile and performing some basic preventative maintenance, you can keep your EDC comfortable, discreet, and 100% reliable all season long.
Here is how to optimize your S&W M&P for the peak of summer.
1. De-Bulk the Frame: The Manual Safety Delete
When you are wearing nothing but a light t-shirt, every millimeter of your firearm counts. Factory manual safety levers are excellent for peace of mind, but their external profile can snag on thin summer clothing or dig uncomfortably into your waistline when carrying inside-the-waistband (IWB).
If you want to slim down your pistol's profile, removing the manual safety is a simple, reversible upgrade. However, leaving an open gap in your frame invites lint, dirt, and sweat directly into the internal sear housing.
The fix is simple and incredibly affordable. You can cleanly seal up the frame using a single factory S&W M&P Left Frame Plug - Manual Safety Delete. For a complete, seamless look on both sides of your frame, it is highly recommended to grab a full set:
-
For standard black frames, use the Smith & Wesson M&P 1.0 & M2.0 Manual Safety Frame Plug Set Black (2-Pack).
-
For Flat Dark Earth setups, you can match your frame perfectly with the single S&W M&P Left Frame Plug Manual Safety FDE or step up to the complete S&W M&P Manual Safety Frame Plug Set - FDE (1.0 & M2.0).
It takes just a few minutes to install, completely flattens the side of your frame, and protects your internals from outdoor elements.
2. Summer Maintenance: Protecting Internals from Sweat
Sweat is incredibly corrosive. When you carry a firearm close to your body in hot weather, humidity and perspiration naturally find their way into the slide components. Two areas are particularly vulnerable on the M&P platform:
-
The Firing Pin Channel: Moisture can seep into the striker channel, mixing with ambient dust and oil to create a sluggish primer strike. Inspecting your firing pin assembly is crucial. If your spring is showing signs of rust or fatigue, dropping in a fresh, complete S&W M&P M2.0 Striker Assembly restores factory-fresh reliability instantly.
-
The Striker Block: Hidden beneath your rear sight hardware is the safety striker block. It relies on a tiny, critical spring to function safely. Ensure this area stays clean and free of rust by replacing a worn-out spring with a factory-spec S&W M&P Striker Block Spring.
3. Check Your Red Dot Hardware
The modern standard for defensive carry relies heavily on micro red dot optics. Whether you are running a factory optics-ready slide or a custom cut, the vibrations from firing combined with summer temperature fluctuations can loosen your optic hardware.
Take a few minutes this month to inspect your mounting screws and check your zero. If you need to remove your optic or adjust your iron sights, always make sure your hardware is locked down tight. If your rear sight retention screw is stripped or showing signs of corrosion from sweat exposure, replace it with a fresh S&W M&P/Equalizer Rear Sight Set Screw to keep everything rigidly in place.
Keep It Original, Keep It Reliable
When your life depends on your concealed carry setup, there is no room for error. Avoid cheap, unverified aftermarket components that introduce tolerance issues to your firearm. Keeping your pistol running smoothly requires sticking to original factory standards.
