Strike Industries PolyFlex Slide Back Plate

A new M&P Slide Back Plate from Strike Industries. Up above that – some new accessories coming from Strike Industries.

Strike Industries describes the SBP as an option for the…

“M&P 9/357/40/45 family of full and compact pistols offers a one-piece quick and toolless option to disassemble your slide. For when you want to clean and maintain your firearm or need to perform a field strip in a crunch, this M&P SBP is a simple to use and affordable upgrade. PolyFlex polymer offers an exceptionally resilient material that has a high heat capacity as well as strong tensile strength while maintaining it’s lightweight characteristics.”

      They’re not talking about field stripping, they’re talking about removing the slide plate. This requires tools for both glock and hk…

        I really don’t consider it a “tool” to compress a spring that relieves pressure to slide the plate off as any pointed object will work even a key. I just don’t see the value as something to put on a gun…
