Description

Here's an incredibly accurate copy of one of the most popular concealed-carry firearms on the market!

This tiny CO2 pistol manages to pack a full-sized, 12-gram CO2 cartridge, plus 20 rounds into its minuscule magazine. But don’t let its diminutive size fool you: This replica mimics the size, weight, controls and even blowback-action slide of its 9mm inspiration so well, it makes for an ideal firearm trainer.

Just load BBs and a standard, 12-gram CO2 cartridge into the magazine, line the green, high-visibility front sight up with the two white dot rear sight on your target and send 20 rounds downrange at velocities up to 295 fps as fast as you can pull the trigger. And, just like the real-steel version, this CO2 pistol's slide locks back following the last shot, so you know, visibly, that it's time to reload.

Really good feel in the hand, finishes are quality and it has a good weight to it. The price is also good compared to similar blowback CO2 pistols. Especially, the spare magazine price is lower than most.

The design of the actual chambering/firing mechanism is really odd, and doesn't perform consistently. The gas operating system is contained in the magazine, and many have reported leaks and inconsistent force necessary to install a CO2 cartridge. The gas system should be a critical area of design focus and where they should allocate the budget, but putting it in the magazine seems to have led to some cost focused decisions, at the expense of reliability. The BB is 'chambered' by having the barrel of the pistol slide backward to seat against the gas piston built into the magazine. This means part of your trigger pull is moving the barrel and engaging an alignment notch, and overall the trigger feels squishy and doesn't have a clear point at which you can expect it to fire. Since the blowback mechanism doesn't chamber the next BB, you actually chamber the round by releasing and then pulling the trigger, and it's finnicky if you don't release fully when trying to fire quickly.

Out of the box, I lubricated everything and loaded it all up. The first CO2 cartridge caused some liquid to burst from the seams of the magazine once punctured, but after tightening down the hex key more aggressively it sealed well. I put the first 18rds through without any issue, but after that started having jams. In the next 100 or so shots, including with a new CO2 cartridge, I wasn't able to go more than 10 shots in a row without a jam or double feed. Overall, this is a gun that, when I pull the trigger, I'm entirely unsure of whether it will fire. Stopping to inspect when I had a jam, I often found only one BB was in the chamber/barrel as expected, but the gas simply never cycled. Other blowback CO2 pistols I've used are massively better in terms of reliability, for example the Umarex Glock 17 G5 fired 300 BBs in a row out of the box with zero issue. The reliability problems really take the fun out of shooting the P365, but I'm hoping it will wear in and improve.

One more observation: There is a pin that fires the gas by pushing into the back of the magazine. Depending on the state the gun is in, this pin is engaged and may damage the gasket around the magazine if you insert or remove the magazine. So, you should either have it cocked, slide locked back, or the safety on whenever inserting or removing the magazine. I can already see a groove scraped into the back of the magazine, and some wear on the gasket from this. I assume you could also damage the firing pin this way.

Not very accurate. Fun to shoot. The nut or screw used to puncture the CO2 cartridge got stripped-out very quickly. I can't charge the airgun anymore. It is useless at this point. On the plus side it does look a lot like my P365.

The P365 Air Pistol aside from just being fun to shoot is the perfect training aid for P365 carriers. Size, weight and functioning closely match the real thing. Add to that, it's really accurate.

Gun looks real nice and feels very nice in the hand. Major issue was that BB's fall out of the clip once loaded. Pointing the gun downward, 5 or 6 BBs fell out of the chamber. Awkward shooting.

Not a good design! Save your money I already warrantied out the first one because of the magazine stripping out. Now the one they just sent me is doing the same thing just after replacing the air cartridge 3 times. It’s a fun gun to shoot and looks crazy real. Just wish it was built differently to last.

Worked great for a few weeks. Now shoots 3-4 BBs out at the same time, then won’t chamber correctly
