It's a very nice pistol, I have more than 15k (exclusively Remington Golden HP) rounds fired with mine. Very reliable and super fun to shoot. I have replaced the recoil spring because it feeled softer, but was still running great with the old spring, changed it before getting problems. I'm using it mainly as a practice gun to replace my M&P9. One of the best buy I ever made.
