Posting my video to share disappointing experience with both Smith and Wesson and Holosun. Smith and Wesson did NOTHING to help me out despite many other people stating they've had the same thing happen to their 10mm. I only emailed Holosun Canada with questions and they said they'd get back to me.......they never did. Even after i followed up with the guy.
Just sharing my experience for anyone who has M&P Core slides *although all my 9mm COREs have been perfectly fine, so maybe its just a 10mm issue*

Full power 10 mm is close to the power of 41 magnum. It will stop a fairly big black bear, 9 mm will get you eaten by a p*ssed off black bear. In BC 10mm is approved for wilderness carry, 9mm isn't, they are very different calibres, for very different purposes. There's just too much energy for a couple of cheap screws. Maybe Black Box can enlarge the screws, or find a way to build in a recoil lug. There's a lot of inertia with the high slide speed of the 10mm.
 
If you had a proper grip, you’d get less muzzle flip with faster follow up shots, but the plate may have broken sooner. :) I agree with Tokay and enefgee.
 
It sucks that you have to spend more money to make something right, when it should have came like that in the first place

The esay fix would be a metal adapter plate, C&H precision makes them out of 6061 aluminum or steel with lugs built in and material built up infront and behind the optic to support it that wont sheer off of have as much movement like your plastic plate did.

I dont think the quailty of the screws are a problem, no optic cut should rely on those tiny screws alone to support the load of the optic. And plastic lugs just dont cut it, especially on something with a larger caliber like 10mm.

That is too bad. Some manufacturers did a fair amount of work ensuring their 10mms could handle the additional wear. Some didn't. Likewise, it seems that only a few optics have been tested extensively with the 10mm. Probably smart not to bother with the optic any longer.

Not sure I agree with your assessment of the 10mm. It is not meant to compete with the 9mm as a fast shooting dedicated personal defence calibre. Maybe it was originally in the 80s and 90s and that is why it failed to catch on. Its recent popularity is more about its versatility. Its proved itself to be a functional hunting and back country backup round in a package much easier to lug than a big magnum revolver. Sadly most use us will not get to use it for that up here.
