I use EMAGs in mine, and they're excellent, but don't fit into the gun by default. Need to file a chunk of the housing of the magazine away, almost to full-thickness, to get it to fit around the magazine-release-button thing. I filed one a little too much and made a hole but patched that with some glue. The workings of the magazine are a removable unit that doesn't need tampering with. On the plus side, the EMAGs don't have the problem with the screw preventing them fitting in, once the housing's filed they're ready to rock.
