“The fit was good, but the threads stripped out during installation. It’s pretty cheaply built compared to something from the factory.”

“Great product, fit my M9A4 perfectly. be VERY conservative with loc-tight; the RDO mounting holes on any of the 92 series Baretta's run into the firing pin channel. Getting loc-tight in there will gum-up your firing pin in no time. Ask me how I know.....”

“I have a Sig Romeo RS Red Dot sight. Claims to have a Pro foot print. The apapter plate Does fit my weapon Beretta M92XI. The adapter plate has 6-32 threads to except the sight. The sight was supplied with several sets of mounting scews. None of them fit. Too short or to long, or wrong thread. The plate also has two round posts or lugs to locate and sight. The post do not fit the the sight. (under sized). I ended up getting 2 6-32 socket head cap screws grade5 at hardware store. Had to gring .025" of the length to make them fit without bottoming. Looks like #@! but works for now.”

We’re sorry to hear you ran into compatibility issues with the optic. Our 49371 mount is not advertised as being compatible with the Sig Romeo RS, so we’re unable to guarantee the screw fitment or locating lug dimensions for that sight. Sig has used several different footprints and mounting configurations across the Romeo, Romeo1, Romeo1 Pro, and other models, so compatibility can vary even when two optics are described as using a similar footprint. Since the mount fit the Beretta correctly and the issue was between the optic and the plate, this does not appear to be a defect with the EGW mount itself. Kind regards, EGW
