Folks, I just picked up this pistol over the weekend, it's the last one on display. I noticed a gap between the front sight and slide. It doesn't really look as worse than the pictures.
Can’t remember if mine is that pronounced (I’ll have to look later when I get a chance), but yep it’s pretty common. Look up some m17 pics online and they all show it to a degree or two. Heck I’ve seen a lot of Sigs that way for years now. Kind of a lack of attention to detail on Sig, but it doesn’t seem to be a problem other than a mild cosmetic annoyance.
I thought of that too, marring the slide during installation for tight fitting sights, but a fitting that's just about right won't do that. The other sig I have is a 226 navy and I don't see daylight on the gap. Or since this is the same issued M17 production line, these won't like happen on commercial ones.
