Well, the Trijicon Tritium night sights are installed.... turned out okay. Just need to get to the range and get the laser zero’d in. Got it loaded up with ball/range ammo for now; probably will use Federal HST when it’s bedside.
Px4 Storm .45 cal = $388 (on sale @ Cabela’s just after Christmas) came with one 9-rd & one 10-rd magazine.
Bought five more 10-rd magazines on sale @ Cabela’s for $29.88 each. Used my Cabela’s points, so gun & magazines were “free”.
Streamlight TLR-2G from Optics Planet for $267.
Trijicon Trintium Night Sights from Optics Planet for $107. So I’m into it total about $375 (hard cash, out of pocket) - not too bad for a very decent HD setup.

In order to protect the clear lens on the weapons light from excessive burnt powder residue while at the range, I do rubber-band a plastic covering from a “baggie” or plastic wrap over it. (Obviously not for the shots it takes to zero the laser).
