The back of the magazine has two columns of indentions and markings that on the real magazine would be holes to indicate the number of rounds remaining in the magazine – from 4 to 15. The maximum capacity of the airsoft magazine is 20 BBs. There is no easier and quicker way to add the much-needed capacity to your Glock 19 than with our Glock magazine extension. On the real steel sight, there is a metal sheet of unknown purpose embedded inside and the sight markings at least seem to be a thin sheet of a slightly off-white plastic. On the KSC OEM part, the rear sight seems to be one piece of plastic with the sight markings painted on in white. There have been many stories of lost Glock rear sights, especially since the KSC/KWA design sight is not screwed in place like on the KJW/Marui Glock designs. The KSC G19 is equipped with adjustable hop-up of similar design to their Beretta series.

content provides rather a set of indentions all around and a similarly designed key. The low profile design is attractive and will not allow it to be snagged on anything and the positioning makes its manipulation quite easy. With the low complication rate and high potential for benefit, aggressive use of this potentially lifesaving intervention is justified. But that’s hardly a high stress area. These plastic parts have no important bearing on the durability of the gun. Given the performance disparities of various types of BB weights, adjustable hop-up is quite a nice feature to have. The magazine is of nice weight, completely black in color and metal. The stock floating valve is plastic, with the upgrade HuricanE and Firefly valves being metal. The KSC G19 retains the unique Glock trigger safety duplicated on the KSC G17, which prevents the trigger from being pulled without the central safety lever being also depressed.

Johnny Custom Glocks being on vacation was only an hour from me, since I am his only sponsored shooter we talk all the time. 039;s and issue) but more importantly a huge reduction in climb/flip and I am able to recover in half the time to get on target for a follow up shot. The blowback chamber is held in place by a screw, which must be tightened from time to time or else the gun will cease to cycle properly. The blowback chamber contains a cylinder and two redundant springs that help cycle it. This is especially helpful as spring can easily be caught on the blowback chamber and bent when re-assembling the gun if not careful since the gun will cycle on only one spring. Because if you do subsequently require a threaded barrel, a complete replacement will be required. This means that replacement of both front and rear sights with OEM Glock or aftermarket night and adjustable target sights should be painless. The rear sight is attached by friction very firmly from the factory, but if it is pushed out of place it can quickly become loose. The front sight is held in place by the same method, with split arms pushed against the top of the slide by a plastic wedge.

Unlike most Western Arms designs, the KSC hop-up here is adjustable by simply pulling back the slide and inserting the provided key to the adjustment groves inside the chamber. The original G17 had two grooves on which a metal key with two teeth provided leverage for adjustment through rotation. Yielding identical grooves with less than .0001 inch deviation between each means the barrels afford excellent accuracy. Unfortunately, this also means that the parts are there and do their job, but are really quite annoying to take apart and mess with. It is one self-contained all-metal assembly, which means that unlike the majority of other guns I’ve taken apart, the recoil spring is contained within the guide rod and does not fly out at the slightest diversion of attention. The cylinder is lightweight black plastic and contains the floating valve to direct gas towards either propelling the BB out of the barrel or towards cycling the slide. To fill the magazine, the latch needs to be lifted by the fingernail from the front of the magazine so the baseplate can then be slid forward to reveal the fill valve. The sights are exact dimension duplicates of real factory Glock front and rear sights.
