Specifically the slide release lever "catch" sensitivity???
Seems a bit out of alignment, and not engaging very well in slide-lock...
I noticed this one a friends gun the other day...
Apparently S&W is aware of this and will send you a label to send them your gun for an "adjustment" by their people...7-10 day turnaround...
Everything else about the gun is very good...The finish is what stands out...A guy at a local range took a metal stapler and banged the heck out of one of the display guns and not a scratch or mar in finish...Impressive...
If you did that to a Glock, it'd just make it uglier!
