The magazine is slim and can fit in a KWC 1911. The spring is strong but the bottom portion is not guided very well. When the spring is pulled down the pin can fall lopsided causing a jam which stops the BBs from feeding. I bought this for my KWC 1911 and I paid the price. The seal on the top of the magazine blew within the first 14 rounds I fired out of it. Terrible design with the spring and the price is over priced compared to what you can get anywhere else. Shame on GI for selling this overmarked and clearly under QC standards. I can't even get the magazine apart to fix it. Wish I could get my money back for a DEFECTIVE product.
