fired 200 reloads through the Metro without cleaning. I'm so spoiled by Glock. I clean my G23 about every 500 rounds whether it needs it or not. My 1911 I was field stripping and cleaning after as little as firing one mag. I'm on this kick because I'm really busy and don't feel like cleaning it yet. I do rub the exterior or outside of the gun down with a clean patch soaked in Ballistol and then a clean dry patch and then silicon cloth every time I handle it. And I have been lubing the gun according to the Wilson Combat youtube vid everytime I shoot it I will clean it in it the morning...more to stop the voices in my head than anythang... How long is too long? The 1911 is a combat pistol right? It can go just as long as the Glock without a super cleaning cain't it? Well maybe not...but I ain't babying this Metro and it's running just fine... I keep expecting this gun to fail and it has been just reliable as the 2008 manufacture G23 that I bought in 2011. Maybe even more reliable because even with mouseloads I don't get brass to the head... Wanna kill these ads? We can help!
