I'm looking at the SA 9MM Model #PX 9130L, which comes with Novak Lo-Mount Sights. I like the sight line the Novaks give. Can I get Tritium inserts for the Novaks from SA? If not, can it be done at all, and where would I look? I've looked at Meprolight, Trijicon & Express...but they don't seem to make the inserts for this model. I'm interested not only in range shooting, but also home defence...and I figure the tritium inserts could be of help in that respect. Thanks for any advice I can get here. ~Rugerguy
