The adjustable versions of these sights popped up at MidwayUSA and I had a coupon code for $20 off an order of $100 or more, so I ordered sets for both the M&P Pro 9 5" and the M&P 22 yesterday. I have it and a sight pusher on the way, so hopefully by about this time next week I'll know for sure how well the sights work and if they'll fit into my Revolution holster.
