1. Streetwise Heat .50 Caliber Air Pistol
Highlight: Unlike other self defense guns, the Heat allows you to maintain a safe distance with an effective range of up to 60 feet. Pepper rounds explode on impact, creating a 6-foot cloud, ensuring perfect aim is not necessary.
Constructive Review: This is a versatile self-defense tool. The gun feels realistic and is excellent for practice. I am using it to teach my boys the proper use of a handgun. That being said, it is dangerous. Hit with the proper ammo, and you could do serious damage. There were no leaks after 3 CO2 carts. I am impressed and will carry this in my EDC bag daily.
The gun is bulky and would not be comfortable to carry. That is why I carry it in an EDC sling. The trigger is crisp and dependable. The sights are decent and are easy to see due to the green paint.If you need an affordable self-defense weapon… This is a great choice when on a budget. It will stop somebody. -Stephen Monchak
Trending Review: Most powerful, shoots metal, rubber, and pepper balls (maybe more?) better than Byrna and hundreds $cheaper. Beyond my expectations, highly recommend! Mind the ricochet! Practice with a softer target. -Shannon
2. Mercury Rise MUB .50 Air Pistol
Highlight: 3-in-1 Quick Piercing CO2 chamber System.
Constructive Review: Looks just like a 1911 at first sight. Very intimidating and that’s where the fun starts. This gun is easy for a woman and packs a very (startling) punch for a man.
I am a gun nut and I bought this for my wife to keep the crazies off her in the parking lot or for great non lethal self defense. Now I bought one too, to shoot the crud out of it.
Quality build, gets three mags plus, of high velocity rounds (18)+ and it makes a loud bang. Set up with aluminum balls and pepper balls alternating. It will get attention. -Thomas A Gibbins
Trending Review: Had to update my review because of the performance of the marker. I have another brand that is tuned this out, it outperforms it out of the box. It’s not perfect, I don’t like how it fits in my hand and it had a problem with the magazine, don’t think it’s a common problem. Even if it was a piece of electrical work and what you get for the price, it’s not the worst defect, it’s not auto firing or anything crazy.
Currently exchanging this one, I’ll soon see how the new one does. Another nice thing is it’s quiet and not heavy on gas. -Samuel F.
Reassuring Review: Great price and pretty accurate. Good feel and nothing fancy. Lots more in depth reviews online, but for a good solid nonlethal for the price, it is great.
I own another nonlethal and this one is better. -Zachary Longfellow
3. Umarex T4E by P2P HDP .50 Caliber Pepper Ball Pistol
Highlight: Shoots .50 caliber pepper rounds, rubber balls, or powder balls; Provides a practical solution for personal and family protection.
Constructive Review: I have 4 of these, the latest one got hit with shrinkflation. They no longer provide 2 C02 cans and the Allen wrench is now half the length, which is a problem. I keep these in a canvas holster, and the longer Allen wrench slid into the magazine pouch and stayed put, the new shortened one will be lost the first time I carry it somewhere.
The gun itself is great. I see some reviews saying 60 shots at full power, I see diminished speed at 20 shots, at 30 shots it no longer penetrates the thick cardboard targets. I’ve also been shot with a new C02 and again at 30 shots, HUGE difference. The first shot at 30ft leaves a large red mark through a lightweight Carhart canvas vest and it stings for 20 or 30 minutes. After 30 shots from a C02, the ball hurts, but barely leaves a red mark and 5 minutes later the red mark and the pain are completely gone.
The accuracy is pretty good up to about 40, maybe 50 yards at the most. I put it in a vice and was getting 6 inch groupings at 40 & 50 yards with light wind, which is pretty good. It will still hit a target at 100 yards, but the drop is considerable and light wind curves the ball several feet, you can see the projectile flying through the air.
It’s a large frame, don’t expect to find a shaped holster for it. Go with the canvas holsters. Even in the holster it still slides between the seat & console in our cars when we have to travel through a non-2A state.
This pepper gun is the best bang for your buck, even after their shrinkflation. -Emrah
Trending Review: Shooters of real guns will find their lethal firearms simpler to operate, and more reliable with feeding, but a pepper/rubber ball launcher is a valuable deterrent when less-than-lethal measures are warranted.
First off: when it hits, it hurts like a mother.
I tried inert powder rounds, and rubber rounds. They all left painful welts through a shirt, a flannel, and a coat. I did not feel the need to escalate to feeling its bite with the steel-core rubber rounds; I’d been hurt enough.I had one failure to feed, in about 5-6 firing tables. In the failing instance, one of the rubber rounds failed to chamber. It was dislodged by slapping the weapon and reattempting to fire, which it then did normally.
I also had difficulty unloading a nonfired inert powder round, which got stuck in the back of the magazine and failed to fall out, even with copious jiggling. I successfully unloaded it by firing that stuck round.
Shooting all 6 rounds very quickly worked rather well, despite the warning in the instructions against doing so, because rapid follow-up shots quickly cool the gas chamber, thereby reducing air pressure and projectile velocity. The welt from the 6th rapid shot (its previous 5 went into the ground) is a tad smaller than the other full-power ones, but it still hurt a great deal.
The weapon is well weighted, and the handle has finger contours which make it very comfortable to grip. I am also quite happy with the fiber-optic sights, even though this is obviously a close range weapon.
The whole system is completely ambidextrous!
In summary: this product delivers, for a self defense deterrent under $100. It is not supposed to maim or wound, however, anyone who can feel pain but doesn’t prefer to, will have to think twice about facing this launcher head-on. It is not an action-hero’s primary weapon system, that would be a real firearm. This is what you use right before you turn your unarmed derriere around, and sprint for all you’re worth, as far as you can while saving enough breath for the 911 call.
4 stars for functionality and value-for-price, 1 taken off for the ugly orange slide, and small reliability concern.
P.S. Be very careful while removing a mostly full gas canister. If you only fire a handful of shots and then depressurize it, the spent canister will be dangerously cold. -Samuel Wicker
Reassuring Review: Bought a Byrna originally based on “You get what you pay for” thought process. Although I had considered the Umarex as well. My wife could not pull the trigger on the Byrna. I guess the grip was too big for her hands. So, I figured I’d get her the Umarex to give it a try.
I’m very impressed with the Umarex. The grip, feel and trigger pull are far superior in my opinion. The Byrna trigger pull is clunky by comparison. Fiber optic sights are great, although in a night situation, standard sights are useless on either. For the cost of a Byrna, they can spare 3 drops of paint for the black only sights.
The Umarex HDP has no clips to fiddle with, uses STANDARD 12 gram CO2 cartridges. It’s super easy to use, comfortable and fun to shoot. I bought another one for my mom who wanted some sort of deterrent. The only thing I find silly is the pic rail for light/ laser attachment.
The projectile loading hole is right where a light or laser needs to be for finger access to the switch. So, you’ll have to cover the loading hole or the switch will be too far out of easy reach.
There are pressure switch options out there which would remedy this problem; however, the light/laser pressure switch combo is going to cost more than the gun.
All in all, it’s fantastic for the price, accurate, affordable, my wife likes it and my mom will be able to use it. It’s a win, win. Highly recommended if you’re considering it. Read the instructions completely…so many YouTube videos out there not detailing the proper complete “how to” on proper use of these. -C. Smith
4. Mercury Rise Torpedo Revolver .50 Caliber Training Pistol
Highlight: Dripping a little bit of paintball marker oil (silicone based) on the outlet of CO₂ cartridge and using this anointed CO₂ cartridge in the pistol grip when you hear CO₂ hissing sound or after every 30~50 rounds you shot with unanointed cartridges.
Constructive Review: I found it excellent for home defense, and very powerful with slugs like devastator. Since the magazine is longer than the Umarex, I put 2 rubber Steel bals per slot, something I had not seen in videos or reviews…
And what a destructive power of both bullets… So far I think it responds excellently. I have seen other people complain that it has air leaks, in my case, I have tried it several times and it works correctly. Don’t forget that the joints and seals must always be lubricated with silicone to take care of this toy.
I hope it continues to work this well for me. –Santiago A. Restrepo
Trending Review: To not have problems with this pistol, make sure that you load ammo from the rear and push it in as far as it will go, plus use gun oil on the CO2 tip. This should solve most encountered problems.
It is a great and powerful gun. It feels good in the hand, recorded over 580 fps on the first few shots, love the fact that you do not need an allen wrench to load CO2, and the magazine is very convenient. All in all this is a great gun with no mods necessary! –Frank P.
Reassuring Review: Great entry level marker with issues. Packs a nice punch, but on the third mag of practicing it started making deflating sounds and then the magazine kept loosely spinning around.
There are no upgrades or replacement parts available so until then it’s not much more than a toy that will not last very long. The CO2 punch system is cool because you can just twist it a quarter turn and it deflates your cartridge. -Yelsew Nafets
5. T4E by P2P HDP Compact .50 Caliber Pepper Round Air Pistol
Highlight: Easy to load; Just pull the follower back, insert six .50 caliber P2P pepper rounds, rubber balls, or powder balls and then slowly release the follower back.
Constructive Review: Yes, it’s plastic, but it feels quite nice in your hand. The balance is good. It’s also fairly accurate at close (10-15 yds) and does pack a good punch on a full CO2 bottle.
It only holds 4 balls, but fires smoothly. The trigger requires a good squeeze, but that’s a good thing. You can get 16 to 20 shots per bottle.There’s a simple mod you can do to increase velocity (on YouTube) but it severely reduces air capacity.
I enjoy target practicing with this in my backyard. –Shelton
Trending Review: Very powerful for a CO2 air gun. Sights are good enough to hit intruders’ upper body. Pepper balls will put intruders in a daze.
So you can safely get away. Almost as loud as a firearm. So definitely NOT back yard friendly to practice or plink.
Steel/rubber 2.7 gram balls will leave a welt and mark to help police identify intruder upon capture. Thanks for this inexpensive, less lethal home defense weapon. –j carter
Reassuring Review: A nice alternative to lethal forms of self-defence. Designed not to hang up on pockets, purses, fanny packs, etcetera. The CO2 design is excellent in that you can carry this for months/years without having to change out the cartridge or replace blown out seals. –Kevin T
