Okay, I know what everyone's thinking. "Crosman? Are u kidding me, ditch that and get a KWA" but hear me out. I picked up a p50 ( an old co2 pistol from Crosman) from a yard sale for like 3 bucks . Of course, the Mag was broke. I liked that it had a moving slide instead of the fixed (c11) . Reasons for not upgrading. Backyard wars only Never for field play Cheap. Already painted it. Crosman does not sale air mag p50 mags anymore . And I was wondering if standard 1911 mags would fit? Because I know the R76 will accept standard AK 47 mags. So some do use aftermarket parts. Thanks , and once again, I know Crosman sucks. I never buy Crosman from the store unless I'm in desperate need of .20's.
