Okay I have looked through the form and couldn't find any info, I just added a S40-A1 to my family. the first thing that I noticed was the Mag release is so hard I have to rotate the gun in my hand to get it in a position to create enough presser to release it. is there anyway to lighten the spring for easier release? was also looking into polishing the Ramp, should it be done ? and the Mag is very tight when installing or removing the Mag. also looking for any tips that would help. I haven't run any rounds through it yet so i'm looking for any info on what the best ammo to use, i was told i needed to run Plus-P. my apologizes in advance if I stepped out of form with this post.
