My PT came from the factory with Novak sights.
Problem is, the rear seems to have come loose somehow.
When I look - there's a little threaded hole, with what appears to be a hex something or another in there. Can't really tell because it's TINY - and I just can't see in this little freakin hole all that well.
Can anyone tell me what size/head this piece is? Clearly it needs to be tightened up a bit. I don't seem to have anything that small though.
