The GAO Bid Protest Docket states that the case is due June 5, 2017. Depending on what the GAO decides, we may not know what exactly Glock protested—beyond not winning, of course. If the protest is denied, the GAO probably won’t explain why. Any aspect of the process or RFP can be challenged, including errors in submitting paperwork that had nothing to do with how the guns actually performed. Protests are pretty common, so don’t regard this as an extraordinary event. Everyone following this process knew they were coming, and there may well be more.
