Hey guys, thought I would share tonites experience with you. A friend picked up a Para GI Expert a while back. His had a 8lb trigger from the facory, and he decided that wasnt good enough. We ordered a 15lb mainspring and a lightened sear spring for it and figured to do a little smoothing inside. Took it all apart, everything looked pretty normal. Went to reassemble and ran into a problem. Apparently the GI expert is no true 1911 spec'd gun. The standard sized sear spring was too short. Took one from a colt to try, same thing. Many people online have posted that these are true 1911s, as far as parts goes. They are not. We ended up modifying the stock Para spring. We have a nice trigger now, and it set off 50 rounds reliably too. Tomorrow we will hit it with a trigger pull gauge and I will report back what we have.
