It will vary depending on the propensity of the private element. Maintaining sufficient spacing between shooting will show some constant gas efficiency. It is the inherent limitation of Airsoft gas guns, so you should understand and use them.

@@크리빵빵 i do understand that, just find it a bit annoying some times when playing with steel kits like my Kimber Royals, thin mags cause its a 1911 platform I'm just asking you how is this kit performing can it shoot all 28 bb succesfully with good blowbacks.

@@theforge4591 look at the speed of blowback and sound. Slow but not too slow and firing sound is more like tuned up equilizer Base boost. That means he used red gas. And have a look the lenght of the slide. it is short slide and fat mag with powerful gas. ofcourse he can shoot all 28 bb succesfully with good blowbacks. Frankly I dont even think that he would need to use red gas just regular green gas also might work perfectly like that. This is psysics. If he used red gas blowback would be much faster and louder. I use 5.1inch super heavy steel slide 1911 kimber with short slim co2 mag. works fine. and I also have STI 2011 john wick pistol full steel CNC. I used red gas and I fired almost 30 rounds with no problem.I dunno that your kimber pistol can load with co2 mag but if you are talking about 1911 steel version with gas mag, it wont be able to fire 13 rounds. maybe 10 or 12 rounds if your lucky? not even red gas will help you at all. Next time write down specific details of your gun so we could provide you satisfied answer. I think you had problem cuz you used gas mag with your kimber Royals. Red gas? like i said, it wont help. Unless if there is rounded slots for co2 mag of your pistol frame. BTW you have beautiful pistol. Kimber Royals? I might be happy even the gun frame is not designed for co2 mags. It is lovely gun. I would be really satisfied if I have your gun. have a lovely weekend. the conslusion of this story, 1911 platform is irrelevent of gun firing functioning

@@antisuicide3032 mine is 1911 Kimber royal II from Ratech, yes it has CO capsule round magwel, in my country to avoid Legal problems i have to use green gas, CO capsules are considered Airgun category here although its under 1J. red gas are those the 16KG one or 14kg preasure? now i already swap the slide to aluminum tho, and just keep the original steel slide as display in my collection rack.

@@theforge4591 16kG of course. and black Guarder gas is 14kg. There is 18kg red gas it was badass. oh under 1J? are you living in Japan, UK or Australia? Where are you living? aww... still If I were you I would change back to steel slide. Best part of steel guns, not only firing with high power, its best when you hold it. Damn I want that Kimber royal. It is no longer pruducing. If I were you, I would change back to steel slide. Its sexy gun dude! and maybe perhaps this might be solution. 1.There is 200$ cost cylinder box. Fully assembled and its made in Korea. That thing is expensive but, it increases super recoil feedback. Only few left in Korea maybe less. I know which shop has it now. However they are planning to reproduce upgraded version in next 6months. 2.take out your recoil spring and use original normal marui 1911 recoil spring. well, theoradically this might solve your problem. BTW who care even you use co2 at home? all you have to do not carrying it outside. or is it just impossilbe to buy co2 mags in your country? then use the black guarder gas with replacing weak recoil spring. This is all I can give as tips. I wish you have happy airsoft life. =D PS: if you use old "Army"(Chinese airsoft gun company) type cylinder, even you use co2 mag it will only show 300FPS and cylinder wont break. I think this is the best way.
