Dynamic Advantage custom spec stainless steel guide rod system for the M&P pistols. The tip is cerakoted for decorative purposes when the slide is in battery.

These are a complete one piece, UNCAPTIVE, and CNC machined guide rod which are drop-in ready units. The endcap is threaded to accept a stainless Torx tip OR button tip, which can allow the user to choose between captured or uncaptured. The tips are cerakoted black to prevent rust, or the user can choose a color of their own.

Our ISMI flat recoil spring is manufactured of certified materials, heat treated for longer life, shot peened for stress relief and finally calibrated to factory specifications. 

The absolute best spring on the market for reliability and longevity, being manufactured from chrome Silicon alloy and designed to perform beyond 20,000 compression cycles.

13lb performs best in most ported or compensated variants. The Carry Comp works very well with this setup. OEM Spec variants with the compensators also work very well. 

13lb will allow users to run 115gr to 147gr, as well as 124gr +P and 135gr +P.

We recommend a 14lb spring for carry or duty use. We have NEVER had a malfunction using the 13lb spring, but we have seen the gun become sluggish around the 3k round mark without cleaning. If you are disciplined with cleaning, the 13lb will work for duty use. It's what we run in our guns. 

We always recommend using a 14-16lb for duty use due to the +P nature of most rounds. Although we run lower spring rates in our guns, we must recommend a higher spring rate in everyone else's duty pistol.

We reccommend using the 14lb spring in 5in slide setups, regardless of porting or milling to the slide. Physics play a role in the slide returning to battery, and our experience is 14lb springs doing so.
