My previous two Glocks (26 and a 21) had zero problems with the stock recoil rod over probably 20,000 rounds each gun. My current Walther is the same with approximately 8,000 rounds. These recoil rods are designed to work for a long time - if Gaston or Karl didn't trust them they woulda put in steel. I have seen videos of the plastic recoil rods flexing mightily during firing - the point was that the flexing is part of what makes the gun run. YMMV!!!
