The lube point is just to help the barrel along since it contacts the slide during operation as the barrel pivots upwards. And as far as steel case goes, my FNS 9 has eaten more Tula than anything else. For the most part, these things just don't care what you feed them.Congrats on your new gun. Glad to see you like it so much. I recently purchased the FNS 9 (10 round magazine per CT laws) with night sights from Bud's. I was surprised to see my test case envelope was dated from September 2013 (21 months ago). I was able recreate the trigger problem by moving the trigger forward that locks the slide. I don't think it's a big deal but I'm keeping my eye it. Like you, I seem to prefer the bigger back strap.
I do have a basic question. One of the lubrication points is 1/4" from the end of the barrel. Just what does this mean? Is it just a drop on the top a 1/4 back or all around or what? Also, do you think steel case ammo like Brown bear is ok to use? The cost per round is pretty low. Thanks
