The recoil reduction is real - DPM SIG P228 & P229 Mechanical Recoil Reduction System

As the title states, the spring system does reduce the recoil of the P365XL. If you use +p defensive ammo, this will help reduce muzzle flip, give you slightly faster follow up, and help to reduce the chance of developing a flinch from using hot ammo like Underwood or Buffalo Bore. My preferred setup was the large buffer with either of the middle length springs. 115gr FMJ is soft shooting, and hot 90gr Underwood XD +p is easy to manage. I do plan on switching to standard pressure 90gr or 68gr XD to benefit from the reduced wear and tear that both standard pressure ammo and the DPM spring system impart to your firearm. Would give 5 stars if the price was between $50 and $75, definitely. Worth it to switch regardless, and an easy recommend.
