So I'm on a Springfield kick and just ordered a XDM in 10mm with coming from Powder River and they are milling it for the Trijicon RMR. Got that sight in today but still waiting on the gun. Also canceled my month long standing pre order with Brownells for the hellcat and just bought it tonight from PSA. Anyhow the guy at my local gun store said the RMR would fit on the Hellcat and I am just wondering if anyone has done this? I would like to order something for the hellcat and would rather spend the extra $80 on the RMR but find it hard to believe it fits and I can't find it anywhere on the net?
