Anything that mimics stock sights including fiber optic. Can not have any thing that requires batteries. There are so many different sights that its hard to say what and what is not legal. Although I dont think peep sights are legal.
someone posted here that the manufacturer was claiming the express 24/7 sights were legal, may want to look in to that. I agree with the previous posts that as most matches are outside (hopefully in the sun) fiber optic is hard to beat.
The only Production pistol that's been "officially approved" with FO sights by IPSC is the CZ SP01, because somebody provided 'evidence' to Vince Pinto that the factory will supply the gun to a cusomer with FO sights. The K100 COMES with FO sights whether you want them or not, but it's not been "approved".
You're right....and that's why I like shooting in USPSA rather than IPSC, and have an FO front sight on my XD40.
Less BS, and I like that. 8)
