Be careful about about how much screwing around you do with your 1911s
I’ve had many family members and friends ask me to go shopping with them to help them pick up a firearm. There have been many times that I have warned people about buying a certain gun even though it looked like it was a good price. Many of the times it was a firearm that had obviously been customized. The biggest warning sights are usually when the triggers have been changed. That can mean that somebody was lessening the trigger pull weight and it’s also a hint that it was turned into a target gun and there may be other parts like springs or buffers inside it. I have a family member that purchased a 1911 because he had one in the military and the one he eye balled at a gun store had exactly these issues.
After we took this firearm to the gun club it actually jammed up on us several times, I tried to take it apart to see what the spring looked like but it had a full length guide rod and I did not have any familiarity with that. We even tried several of my wilson combat magazines that usually solve many 1911 problems but the gun still hung up. We later found out that there was a tool we needed and there was in fact a buffer that was decaying inside the gun and causing all of the malfunctions. There are so many new 1911s out there, Sigs, Les Bauer, Kimber ect. that you have to watch the amount of tinkering people do with them because not all of the 1911 parts and especially holsters are going to work with them.
