BME 1911 Slide Scope Mount Experience?

I'm considering buying a BME slide scope mount for one of my 1911's.  (I've heard good things about their High Standard Victor scope mounts, but ended up ordering one from Al Marvel.)  Does anyone out there have experience with this particular 1911 slide mount?  Is fastening only in the former iron site groove robust in the long term?  Are fit and finish good?  The link is below.

I have a mount for my S&W model 52-1. It is high quality. I have no experience with this particular mount. All I can say is that BME has been around for decades and although his mounts aren't cheap, they are of the highest quality. I don't think I've ever heard a complaint about any of them. I'd contact BME and tell them what scope you are going to mount and if their mount would work.
