Beretta M9A1 - 92FS

[kg5ie]

Just got this in on an end-of-year addition to my classroom teaching aids. Have not had a chance to shoot it yet, but from all of the discussions on many forums I went ahead and ordered a multi-pack of springs to adjust the trigger pull. The factory std. hammer spring is 20lb. I got a set of 16, 17, 18, 19.

Anyone out there tinkered with this that can give me an idea of how low I can go on the spring tension before I start having issues? If so, thanks for sharing your thoughts and experiences.
