PT1911 manufactured in 2008. Before I bought it last January the front sight had been replaced with a HiViz fiber optic. I picked up the matching rear sight, but never got around to having it installed.

Here's my problem: The PA State IDPA Championships are in 2 weeks, and my front sight broke during yesterday's match . I am willing to buy a replacement sight and have both front and rear installed, but time is short.

Suggestions?
