Tuning your P320 for the performance you want can be difficult. Especially if you are cooking up your own loads that may not be to factory ammunition velocities or Power Factors. Sig specific recoil springs can be hard to find in the weights you want or not found at all. However, 1911 recoil springs can be found in a wide variety of weights. The drawback is that they do not fit the P320 with it's factory guide rod. The way to get around this is to replace the guide rod in your P320 with one that will accommodate 1911 springs. With a simple swap of the guide rod you can now use pretty much any full size 1911 recoil spring to tune your pistol for the function and feel you are looking for. 320 or the X5, will dictate which recoil guide rod to purchase. LIGHT / MEDIUM or HEAVY. Or purchase them individually ranging in weight from 7 to 18 pounds.
