Shipping was quick as wellOn Noveske FMRS Forward Mounted Rear Sight for DM SlideLLawrence N.Verified Buyer4.0 star rating05/09/25Really nice, BUT. . .Review by Lawrence N. on 9 May 2025 review stating Really nice, BUT. . .A really nice piece, machining seems flawless, Echelon COG fits perfectly. Extremely comfortable in the hands under recoil, 3 fingers fit fine, especially with the Sharps Bros mag funnel. BUT, available real estate for support hand purchase is minimal, so I'm not sure this will be a keeper for me or not. If the grip was a little larger, this would be a keeper for sure. My hands are not particularly large.On Sharps Bros Springfield Echelon Grip Module - Black Out Aluminum$465.00 -
