Why Choose Pistol Grip Grease Guns?
Pistol grip grease guns (trigger grease guns) are designed for one-hand operation, making them ideal for applications where the other hand is needed to hold a component or access a grease fitting in a tight space. Unlike lever action grease guns that require two hands, pistol grease guns let technicians work faster in confined areas. They deliver 0.4 to 0.68 grams of grease per trigger squeeze at pressures from 3,000 to 10,000 PSI.
The trigger mechanism provides controlled grease delivery. Each squeeze dispenses a measured amount, reducing waste and preventing over-lubrication. Mini models (S-801, S-802) hold 85g / 3 oz. for precision work, while standard models hold 400g / 14 oz. with cartridge, bulk, suction and filler pump loading. All models accept 1/8" BSPT, NPT and M10×1 threads.
For high-volume applications requiring both power and convenience, our dual-mode models (S-808, S-808W) switch between pistol and lever operation at 7,000 PSI, giving you the best of both worlds in a single tool. The S-810 Switch Model goes further with 10,000 PSI in high-pressure mode.

Frequently Asked Questions: Pistol Grip Grease Guns
What is a pistol grip grease gun?
A pistol grip grease gun (also called a pistol action or trigger grease gun) uses a trigger mechanism for one-hand operation, dispensing grease with each squeeze. The pistol grip design allows the operator to hold the gun like a handgun, making it ideal for tight spaces where a two-hand lever action grease gun would be impractical. STAR pistol grease guns deliver 0.4 to 0.68 grams per stroke at pressures from 3,000 to 10,000 PSI.
Can I operate a pistol grip grease gun with one hand?
Yes, that is the primary advantage of a pistol grip design. The trigger mechanism lets you squeeze grease out with one hand while the other hand holds the coupler on the fitting or steadies the component. This is especially useful when working under vehicles or inside engine compartments where space is limited.
What PSI do I need for my application?
For most automotive and light industrial work, 3,000 to 5,000 PSI is sufficient. Standard pistol grease guns like the S-803 deliver 5,000 PSI, which handles ball joints, U-joints and chassis fittings. For heavy equipment, mining or sealed bearings, choose the S-803S or S-804S steel head models at 8,000 PSI. The S-810 Switch Model delivers 10,000 PSI for the most demanding applications.
What is the difference between pistol and lever action grease guns?
Pistol grease guns use a trigger for one-hand operation (3,000 to 10,000 PSI, 0.4 to 0.68g per stroke), while lever action grease guns use a two-hand pumping lever for higher pressure (up to 12,000 PSI, 1 to 2g per stroke). Pistol models are better for tight spaces and quick jobs. Lever models deliver higher volume per stroke and are preferred for heavy-duty industrial applications. Our S-808 Dual Mode combines both mechanisms at 7,000 PSI.
What is the difference between standard and heavy duty pistol grease guns?
Standard models (S-803, S-804) use die cast heads and deliver 5,000 PSI, while steel head models (S-803S, S-804S) deliver 8,000 PSI with stronger construction for industrial use. Steel head guns handle higher pressures without deforming and last longer under daily heavy use. The professional models (S-803/PRO, S-807) also feature enhanced output per stroke at 0.5 to 0.68g, making them faster for high-volume greasing.
What is a dual-mode grease gun?
A dual-mode grease gun can operate in both pistol action and lever action modes. Our S-808 and S-808W models feature a switchable design: use pistol mode for tight spaces and lever mode when you need maximum pressure. This eliminates the need to carry two separate grease guns. The S-808 delivers 7,000 PSI with 0.65g per stroke output.
How do you load a pistol action grease gun?
Pistol grease guns support multiple loading methods: cartridge, bulk fill and suction fill. For cartridge loading, unscrew the barrel, insert a standard 400g (14 oz.) grease cartridge (or 450g for Australian market models), and reassemble. For bulk filling, use a grease bucket pump or our grease filler gun to transfer grease directly into the barrel. Mini models (S-801, S-802) accept 85g (3 oz.) cartridges only.
What are clear tube grease guns used for?
Clear tube (transparent barrel) grease guns let you see the grease level inside the barrel without opening it. This prevents running dry mid-job and helps with inventory management. Our clear tube models (S-801CL, S-803CL, S-804CL) are popular in automotive workshops where multiple guns are in rotation and operators need to quickly check which guns need refilling.
How do I bleed air from a pistol grease gun?
Loosen the barrel head half a turn to let trapped air escape, then squeeze the trigger 8 to 10 times until grease flows from the coupler. If grease still won't flow, check for an air bleeder valve on the gun head (a small screw). Open it while pumping to release the air lock. Air pockets are the most common reason a grease gun stops pumping. They typically occur after loading a new cartridge or when the gun has been stored for a long time.
What is a spin-on grease gun?
A spin-on grease gun (like our S-809) uses a threaded coupler that screws directly onto the grease fitting. This creates a leak-proof connection that won't pop off under pressure, ideal for hard-to-reach fittings where a standard push-on coupler might disconnect. Spin-on couplers are common in heavy equipment and agricultural machinery.
Where are pistol action grease guns used?
Pistol grease guns are widely used in automotive workshops, agricultural equipment maintenance, construction machinery and manufacturing plants. They are especially popular for greasing chassis fittings, ball joints, U-joints and bearings where access is limited. The one-hand operation makes them the preferred choice for technicians working under vehicles or inside engine compartments.
Do you offer OEM pistol grease gun manufacturing?
Yes. We provide full OEM and private label manufacturing with custom branding, specifications and packaging for all 19 pistol grease gun models. We supply distributors and industrial buyers in over 27 countries. Visit our OEM partnership page for details on bulk orders and export supply.
