Works great in KWC-derived 1911's
Fits my Remington RAC (KWC manufacture) 1911 just fine and it's nice having so many shots. Mine came retail packed and included an extra Allen (hex) key.
Only negatives are the high shot count tends to cool the CO2 down very quickly and one CO2 bulb won't last 2 mags, although that said even with normal magazines you'll be pressed to get more than about 45 shots out of a bulb.
Overall though I recommend it. It only cost me an extra £8 over the standard capacity mag and is fine provided you give it a chance to warm up for a second or two between shots.
