Have a 9mm Shield so-so trigger. About 7.5-8lb and lots of pre travel. A bit gritty also. Thought someone said they sent their pistol in to S&W and was very happy with the returned weapon. Much better. Any one with experiance with S&W repair for this issue. Appreciate any thoughts. I know I can do Apex sear only for much improvement but still looking for the free repair....

Thanks for any info and/or thoughts
