Well, I guess this was my own stupid fault. After cleaning the guns today, I went to reassemble the P3AT, and I think I mis-aligned the guide rod because now the slide is locked up, and fully to the rear. It won't budge in either direction, I can't insert the assembly pin, and the guide rod is at a noticeable angle (high at the barrel end to low at the breech end). Any ideas of what I can try myself before I take it to a gunsmith/the factory? Pics will come later if necessary...
And like I said, this was my own stupid fault.
