Maximum Capacity for Fixed Locations
When you’re keeping pepper spray in a fixed location — a nightstand, glove box, desk drawer, by the front door — you don’t need compact. You need enough spray to handle a situation and enough range to maintain distance between yourself and a problem.
That’s what four ounces gets you. It’s the largest Pepper Shot canister size, and it’s designed for people who have decided that running out halfway through is a risk they’d rather not take.
Who This Pepper Spray Is For
Homeowners who want a defensive option at entry points or bedside. Drivers who keep spray in their vehicle and don’t need it to fit in a pocket. Property managers, security staff, or business owners covering fixed locations where having extra capacity is worth the larger size.
If you’ve ever looked at a half-ounce canister and thought it didn’t seem like enough, this is the other end of the spectrum. It’s not subtle, it’s not lightweight, and it doesn’t pretend to be a keychain accessory. It’s the option you grab when you’ve already decided you need pepper spray and you want as much of it as possible.
Is This the Right Choice for You?
Choose the Pepper Shot 4 oz if you want:
- Maximum spray capacity for home, vehicle, or office storage
- Extended range up to 18 feet with the flip-top stream model
- Choice of spray pattern — stream for accuracy, fogger for wide coverage
Consider something else if you need:
- Daily pocket or keychain carry — this is too large for that
- Wind resistance — gel formulas are better for consistent outdoor use
Why Capacity and Range Matter at Home
The 4 oz size gives you 18-20 one-second bursts — enough to handle multiple short deployments or repeated sprays if your first burst doesn’t land where you intended. Under stress, accuracy suffers. Having more spray means you can afford a miss and try again without worrying about running dry.
Stream models reach 13-15 feet, and the flip-top stream extends that to 15-18 feet. Fogger models reach 13-15 feet but cover a wider area, which can be useful indoors or in confined spaces where precise aim is harder. All models use the same 1.2% Major Capsaicinoid formula at 2 million SHU — the same active ingredient concentration across Safety Technology’s entire Pepper Shot line. What changes between configurations is the delivery pattern and safety mechanism, not the formula itself. UV dye marks anyone contacted by the spray, which matters if you need identification after someone has left the area.

Practical Details
Available in three configurations: PS-4S (4 oz stream with locking actuator), PS-4FT (4 oz flip-top stream), and PS-4F (4 oz fogger with locking actuator). All contain 4 oz of 1.2% MC spray at 2 million SHU. Stream models deliver 18-20 bursts at 13-18 feet depending on configuration. Fogger delivers 18-20 bursts at 13-15 feet. Weight ranges from 0.41 to 0.5 lbs. All include UV marking dye. Made in the USA by Safety Technology. Replace every 3-4 years even if unused — OC degrades and propellant loses pressure over time. Cannot ship to Massachusetts or New York.
Keep serious capacity where you need it most — at home, in your vehicle, at your desk. Be Prepared and Be Safe.
Frequently Asked Questions
Should I choose stream or fogger for home defense?
Stream gives you better range and accuracy with less blowback risk, but requires more precise aim. Fogger covers a wider area and is easier to connect with under stress, but you risk catching yourself in the spray in a confined hallway or room. For most indoor situations, stream is the safer choice. Fogger makes more sense for outdoor use or when you need to create a barrier across a wider opening.
What’s the difference between flip-top and locking actuator?
The flip-top (PS-4FT) uses a hinged cap that flips up to expose the trigger — faster to deploy with one motion. The locking actuator (PS-4S, PS-4F) has a twist-lock mechanism that requires an extra step but provides more security against accidental discharge. For storage in a nightstand or drawer, the locking actuator is generally safer. For quick-access situations, flip-top has a slight speed advantage.
Can I keep this in my car year-round?
Extreme heat and cold affect spray performance and shelf life. Temperatures above 120°F or below 32°F can damage the canister or alter the propellant pressure. If you live in a climate with significant temperature swings, store it in the glove box rather than on the dashboard, and inspect it periodically. Replace sooner than the standard 3-4 year recommendation if you notice any canister damage.
How do I know when this needs to be replaced?
OC pepper spray degrades over time even if the canister has never been used. Propellant pressure also drops gradually. The general rule is 3-4 years from manufacture, but many people set a calendar reminder for 3 years to stay ahead of it. If the canister shows physical damage, corrosion, or the actuator feels loose, replace it immediately regardless of age.
