When i bought my PRO TLE II, used as well, i had some various issues,mainly stovepiping.. One day @ the range she went full auto on me.The seer was cracked,causing the auto malfunction, but the smith informed me of various mods that were done over it's lifetime, and it was not going to be reliable unless we brought it back from the edge so to speak. It now functions flawlessy no matter what i feed it. I use wilson combat and novaks mags. had feed issues with the std kimber mags.from the trigger i'd say that pistol you have has obviously been worked, take it in for a looksy/tune up. in central FLA you should have no problem locating a good smith, with the abundance of gun stores in that area. it sure is dirty. Just look at the difference from my feed ramp vs. yours.
