I'm developing a sneaking fondness for the one I have here, despite the accuracy mentioned in another post.
As an entry level pistol I think it offers pretty good value, and gives a new or relatively new shooter some extras right off the bat that would cost extra to put on if he or she bought the Mil Spec version.
Personally, I'd look at replacing at least a couple things to make it what I'd like it to be, but even if you replaced the two-piece barrel, the sear, the disconnector, the firing pin, the grip safety, the ambi safety, the hammer, and the guide rod, you'd do most of that in bringing the Mil Spec up from a base pistol anyway, and the much better Novak sights would cost about $150 in themselves just to buy, not counting installation.
The PX9109L gives you an "advanced" pistol configuration that can be left as is for casual use, or upgraded here & there for serious use as you go along. You can shoot it & see what the add-ons do for you.
