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
