I dissasembled my C9 to polish the feed ramp. I removed the barrel. I wasnt planning on removing anything else but in the process of pining the barrel back in the safety, sear assembly, sear assembly spring and sear block flopped out. After I cleaned, lubed everything I put everything back, cycled some snap caps thru it. Seemed to cyce fine but, It feels like the trigger is harder than before. Any ideas what may cause this? I am 99.95% sure I put everything back together right. Since I am unsure I will most likely take the slide off again and have another look with a fresh set of eyes. I have read thru the sticky on assembly many times but, does anyone know of any other take down graphics they could point me to?
