Was hesitant to buy but wow.. - DPM CZ 75 Compact Mechanical Recoil Reduction System

Installed in a PCR which is a whippy little pinker, but this DPM recoil assembly really works, using the longer heavier spring 115 and 124g hardly kick at all, and 147g although less velocity but heavier bullet dulls the impulse. Was hesitant to spend the money or add ports but this DPM works really well. Also have a 2 ounce brass base on the mags which helps balance the pistol. This should also work fine in the compact and P01 variant.
