While my tests were far less than scientific, I did trigger pull tests prior to and after installing the new connector. The measuring was done with a set of digital pull scales, but they weren't true dedicated trigger scales.
Before installing it, my trigger pull averaged 7.6 pound over ten pulls. After the installation the average for ten pulls was 6.3 pounds. That is a 1.3 pound reduction or a roughly 17% improvement.
I also installed one in my Glock 19. It improved the Glock much more than the Ruger. I didn't measure the pre installation pull weights, but the post installation weights did hover around the professed 3.5 pounds.
I too had similar results with the Ghost ultimate connector. However, imidiately after reasembling the pistol and dry firing numerous times, I took it back apart and bent the small end tang on the connector inwards slightly. That made a more noticeable difference in the pull. Next, I removed the magazine connector from the slide and that also helped in my case as it seemed to have been draging. (This is not the case on all though.)
As I continued to put 400 more rounds through the gun, the pull has improved even more to an average 5-5.4 lb. pull W/3/8" of trigger travel on the first trigger pull and 1/4" travel on repeating pulls with slight pressure on the trigger.
I have yet to do any internal polishing which could help even more.RugerForum.com :: View topic - SR9 How-To (Multiple Inside) Updated 4/5/09 W/ Videos!
