I would choose not to use them because you probably won't be wearing them in a real life defensive situation. I doubt they would really help anyway. That trigger pull is something the shooter just has to learn to deal with. I think it is the only real drawback to the LC9.
But the lc9 is designed for carry that's why the longer trigger pull. I'm a revolver man and I find the lc9 comfortable for me ... I shot 50 rounds thur it other day and that was to much actually. But really I shoot it just as good as my 1911's
I use the "FINGERLESS" Wells Lamont work gloves. They are about $6.00 a pr at Wal Mart. They have a decent leatherette palm, and stretches nicely over hand. I like the open fingertips. They make for a decent range glove. Especially in hot muggy areas (Like South Texas). They help keep my hands dry, and sweat off my firearm.
