Suttner ST-2700 pressure washer gun with stainless steel internal plumbing and a reduced-effort trigger pull. This is the trigger gun contractors switch to when they get tired of squeezing a stiff gun all day. The relaxed action mechanism cuts trigger effort by about 40% compared to standard spray guns, which means less hand fatigue on 8 to 10 hour job days.
Stainless steel inlet and outlet fittings resist corrosion from chemicals, bleach, and hard water. The 3/8" inlet and 1/4" outlet are the standard contractor thread sizes. Rated to 5,000 PSI and handles water temps up to 300 degrees F, so it works on both cold water and hot water pressure washers.
Why the ST-2700 Is the Most Popular Contractor Spray Gun
Professional pressure washing is an all-day, every-day job. You are squeezing and releasing a trigger gun hundreds of times per day, 5 or 6 days a week. A cheap gun with a stiff trigger will wear out your hand by noon. The ST-2700's relaxed action mechanism uses an internal spring system that reduces the force needed to hold the trigger open, so your hand lasts as long as your work day.
The stainless steel plumbing is the other reason this gun sits on more contractor rigs than any other model we sell. Brass guns corrode when you run bleach and sodium hypochlorite through them daily. Stainless resists that corrosion and lasts 2 to 3 times longer than brass equivalents.

How to Choose the Right Pressure Washer Trigger Gun
Not all spray guns are the same. Here is what to look for when picking a replacement or upgrade:
PSI and GPM rating. The gun must be rated at or above your machine's maximum PSI and GPM. The ST-2700 handles up to 5,000 PSI and 10.5 GPM, which covers virtually every contractor-grade machine on the market.
Inlet and outlet thread sizes. Most professional machines use 3/8" inlet and 1/4" outlet threads. Consumer machines sometimes use M22 threads. Check your hose and wand connections before ordering. If you need an adapter, we carry M22 to 3/8" adapters in our fittings collection.
Trigger effort. If you are washing all day, a relaxed action or easy-pull gun makes a real difference. Standard guns require 15 to 20 lbs of squeeze force. The ST-2700 drops that to around 10 to 12 lbs. Your hand will thank you at the end of a long day.
Material. Brass internals are fine for occasional use. If you run chemicals daily (especially bleach or SH), spend the extra money on stainless steel internals. The corrosion resistance alone extends gun life by years.
Pressure Washer Gun vs. Spray Gun - What Is the Difference?
Nothing. Pressure washer gun, trigger gun, spray gun, PW gun - these are all the same thing. It is the handheld control that connects your hose to your wand and controls the flow of water with a squeeze trigger. Every name refers to the same piece of equipment.
When to Replace Your Pressure Washer Gun
Trigger guns are a wear item. Here are the signs yours needs replacing:
Leaking from the trigger area. Internal seals wear out over time. A small drip becomes a steady stream, and eventually you are losing pressure and soaking your hand all day.
Trigger feels stiff or sticky. Corrosion and chemical buildup inside the gun body makes the trigger harder to pull and release. Once it starts sticking, it only gets worse.
Water bypasses even with trigger pulled. When internal valve components wear, water bypasses around them instead of flowing through the outlet. You lose pressure at the wand and the gun feels weak.
Cracked or corroded body. If you see green corrosion on brass fittings or cracks in the gun body, replace it immediately. A gun failure under pressure is a safety hazard.
Most contractors replace their spray gun every 1 to 2 years. If you run bleach or SH regularly, stainless steel guns like the ST-2700 will last significantly longer than brass models.
Frequently Asked Questions About Pressure Washer Guns
What thread size do pressure washer guns use?
Professional contractor guns typically use 3/8" FPT on the inlet (where the hose connects) and 1/4" FPT on the outlet (where the wand connects). Consumer guns often use M22 threaded connections. The ST-2700 uses the standard 3/8" and 1/4" professional thread sizes.
Can I use this gun with a hot water pressure washer?
Yes. The ST-2700 is rated to 300 degrees F, which covers hot water machines. It is not rated for steam. For steam applications above 300 degrees F, you need a steam-rated gun.
What does relaxed action mean on a pressure washer gun?
Relaxed action (also called easy-pull) means the gun uses an internal mechanism that reduces the force needed to hold the trigger open. Standard guns require about 15 to 20 lbs of squeeze force. A relaxed action gun drops that to around 10 to 12 lbs. The difference adds up over an 8 hour work day.
Will this gun work with my consumer pressure washer?
It depends on the thread connections. Most consumer machines use M22 threaded connections, while this gun uses 3/8" FPT. You can use an M22 to 3/8" adapter to make it work, but make sure your machine's PSI does not exceed the gun's 5,000 PSI rating.
Do I need to buy a wand separately?
Yes. The trigger gun is just the handle with the trigger mechanism. You need a wand (also called a lance) to connect between the gun outlet and your nozzle tips. We carry wands in various lengths in our guns and wands collection.
