Glock G17 Gen 5 .43 Caliber Paintball Marker Magazine

I have bought 2 so far. I’ll be buying more in the future. These are awesome! I have had no issue. The quick-pierce works well and allows me to keep the CO2 in the mag indefinitely until I need to use it. I use my setup strictly for self-defense. I have practiced with both mags that I own, multiple times, and the seals all hold up well. Great product!

This Glock magazine is simple and easy to use if you follow the instructions and tighten the small wheel to the to it’s stopping point. Great not to have to use tools to charge the co2 capsules. Hi quality product. That being said this magazine seems to only hold 7 rounds instead of 8. I can’t say if others have found this to be the case. It functions with no jams. Thank You.

Excellent quality

This mag works Great! I have had two for about a year now. CO2 cartridge is not activated until given a sharp slap on its bottom. Will buy again.

Here is an explanation and photo for those who don't know what the small plastic part that comes with the Glock 17 Gen 5 magazine is for. In the photo, I show the CO2 release valve on the magazine. This small black item is designed to conveniently and comfortably release the CO2 gas so you can remove the cartridge. If you don't release the CO2 gas, the cartridge will be under pressure, and you won't be able to remove it. Attach this plastic part as shown in the photo and press; you will hear the gas release. If someone has thrown away this small black plastic piece, don't worry. You can press the valve with a screwdriver to release the gas and remove the cartridge.

Definitely the mag I ordered! However, when I put it in the gun, all it does is jam everything up! I don’t know what the hell to do with this thing! I got it to be able to replace the Quick pierce mag and yet this one is proving to be useless! Not very happy! Being very generous with the three star rating right now

I feel I made a terrible mistake purchasing the T4E Glock because I was actually looking for something I could use for dual purpose: training via paper targets and force on force matches as well as up close and personal less than lethal self-defense like most of these products are made for. While the Glock is no doubt made to high quality so far it doesn't see to have the foresight the other markers in the T4E line do.. All of the other markers, the TPM1, m&Pv2 and Walther PPQ all have a "quick puncture magazine available. This Glock simply does not. I checked the umarex site and none are listed. This magazine itself is good enough for paintball use. It is made well and comes with a innovative new feature allowing a player to swap CO2 without using a tool by simply swiveling the baseplate to the side and loosening the thumb screw, then tightening it again and swing the base plate back into place which punctures the CO2. However, 24 hours later it will leak and run dry so this is not a magazine you can install CO2 in and leave in your nightstand or take with you walking the dog like all the others. It's not going to be ready when you need it and will have to be swapped under stress- potentially while you are facing violent aggression. Don't buy this product for self-defense purposes and if you did, send it back and by something else instead. What's the difference? Well a new Glock and new magazine out of the box with a new CO2 cartridge actually did in fact put whole in my front door at 39 feet. All we ask for effective self-defense is good stopping power at 21 feet but no it didn't penetrate the door, just knocked. whole in it teaching me it was not in fact solid like I thought. On a paintball player that's gong to leave a mark (see my other review on this marker if they ever approve it) so this might actually be over rated for some fields. You get close to 40 shots out of it before the gas runs out. How does this compare to the "quick puncture" magazines available for the other T4e products? Well the biggest difference I notice is that those "self-defense" magazines use almost all of the gas for just 8 shots with more high pressure gas per shot, while the paintball just playing around magazine gets almost 40 but with less pressure and power.. Also those quick puncture magazines all have swappable springs that come with them so you can load balls other than paintball or powder-puff balls. A stronger spring means more compression and that means higher pressure out of the gate for stun ball or self-defense balls, like those riot ball jawbreaker rounds. this magazine does not allow you to swap the spring on it so it is clearly designed for paintball only and that's perfectly fine but I feel buyers need to know what they are getting after establishing the precedent with the quick puncture magazines on all of theater products. To add a little insult to this disappointment, this Glock is fully twice the price of all of the other markers and those clearly are more versatile and useful I in a variety of locations and situations. You are paying mostly for expensive licensing trademarks on this product and while it is certainly made well and attractive it is in actual use less versatile and less useful being really only restricted to paintball matches alone. skip this product and the gun it's made for , save the money and get the generic TPM1 or competitors pepper ball launcher instead.

I love that you don't have to puncture the co2 right away. You can puncture it when you want to!
