Gap between holosun eps carry and slide cut - Smith & Wesson S&W Shield/Shield Plus Slide Assembly

The optic cut on the slide left a gap between the bottom of a Holosun EPS Carry and the slide cut. Looking down the slide, the optic looked like it was canted perpendicularly to the slide. I thought the optic cut on this factory slide would be superior to mailing my existing slide to a custom shop to be milled, but I was wrong.

I would not recommend buying this optic ready slide, instead, find a reputable custom shop to mill and refinish your existing slide for your chosen optic.

The optic zeroed and it seems to work, but it's frustrating to spend 600$ on an optic and slide to have it fit poorly and be canted.

I may call Smith & Wesson support line but I'm not confident there is anything to do, if the optic zeros does, it really matter if there is a gap between the bottom of the optic and the slide?
