[Set] Replica SAI 1911 Long Slide [EMG] + Green Gas Magazine for 1911 Pistol Replicas [Double Bell]

Low price, strong blowback. Quite gas efficient, I would say. I disassembled the gun, greased it, because there is almost no grease in it and filled up 130PSI Green gas. You can shoot two mags, 44 rounds, with one gas charge and it will lock back the slide. The slide does have a very small wobble to it, but it's a cheap replica. I like it so far, shot 5 full mags, it holds gas and doesn't leak. I guess you can load even stronger gas, but I haven't tested. It is a TM gas system copy, haven't checked compatibility with different mags.
Lube it when you get it, it's rather dry. The safety is very light on mine, you need to use your thumb when you grip it.
