I have two 110's I bought new.One I bought 30 years ago and one titanium 560 I have it for 10 years now.Both have side bladeplay from new, from the time I have them.I hate both because of that and they are hardly used for now.They never did leaved the drawer for years now.
I checked all 10 of my 110's and they pretty much all have side to sideexcept a couple, and all of them have a bit of up and down which is normalwith back locks. The one's that don't have the side to side just happen tobe old around '65, or '66's.Unless it's excessive I think it's pretty normal for a 110 to have a bit of play.
