PT 92, yet another question

[isnake]

I picked this gun up from Adirondak47 I think his name is, and I have no complaints. I just ran my 1,000th round of Silverbear 115grain hp through it, whoo hoo (I'm actually getting quite good w/this pistol, it's a keeper!). The gun has a strange habit though, I have 5 15 rd mags and it cycles every round perfectly...except for the very last round in the mag. At this point the slide kicks back like it's empty, but there it is, 1 more round in the mag, cycle the slide and that last shot goes off w/out a hitch. I picked up another mag at the show just to see if it was somehow the mags but lo and behold, same behavior.
Any ideas?
