Mounted on my sig p320 x5 - Evolution Gun Works Vortex Viper/Venom Sight Mount

Let me preface this by saying I gave 4 stars only because I ordered it July 13th and it JUST was delivered on Friday 10/9, ( 3 months later) I realize everything everywhere is delayed but at the time of purchase I was told 2-4 weeks and I thought that was long, now at least they are saying 2-4 months. Otherwise it was perfectly packaged and comes with everything you would expect it to. So I have been looking for an RMR since the day I bought my X-5 right when sig came out with the bullshit “ NY SAFE ACT “ version. Nothing bad to say about the X5 as anyone that owns one would know, other than the ONLY red dot that fits it is the Romeo1. I HATE that they did that on a pistol that is considered a competition gun but I digress. When the venom was introduced I had seen something somewhere about it fitting on the X5 but it wasn’t real convincing and no info on how, so I was skeptical but so far I have refused to pay the $400-$450 for the Romeo 1 So it was time and I ordered it. I’m here to say officially, that it fits on the Sig Sauer P320 X-5! All you need to do is take a few mins of filing the REAR side of the RMR cut on the slide, use the longer set of screws they provide in the box, set the provided picatinny rail mount plate aside because you don’t need it, and mount the Venom directly to the holes in the slide and muah...���� perfection. I haven’t used it yet. I supposed that could change my star rating but I think I will be ok, as long as it holds zero and holds up to the elements and usage. So that’s my review. I really just wanted to put this out there so anyone questioning if it will fit on the standard Sig P320 X5, has an exact answer. YES! After removing the stock rear sight and about 3-5 mins of filing the REAR of the RMR cut on the slide, very easy and fits perfect. So if you want to save a solid $200 on an optic for your Sig X-5, go ahead and pick up the Venom. With a little shave, IT FITS PERFECTLY!!
