I cleaned my P3AT today (brand new) and tried to reassemble it and had a problem. First, after I added lube to the trigger axis, I pulled the trigger to work the lube in and the hammer went all the way forward. I pulled it back with my finger and when I tried to put the slide back on the ejector was sticking up and wouldn’t allow the slide to go all the way back. I was able to push the ejector down only by turning the frame upside down on the bench and pressing it in. The slide did go on but this seems odd to me and why did the hammer go all the way forward? What did I do?
