Word is that Agency Arms will be announcing their AOS cut available for the M&P’s at Shot show next month.
Even if S&W does release the 4” and 9L 2.0 COREs, I think the AOS is the best modular RDS mounting system on the market. I might just pick up a black 2.0 9L in anticipation of Agency taking on the M&P AOS cut.
