During IPSC practice tonight my rear sight blade flew off. (Blade only sight was still in cut)
I could reassemble the screws and such but do not trust this rear sight anymore.

It is an STI trojan in 40, and has the big bold TROJAN lettering, i wish to know which sight cut these have or how to measure this? This model is more recent than the horse picture one.

My backup STI trojan is 2015 with small lettering, i tried cannibalizing and switch sights but they don't fit.

Any idea where to start with this?
 
Its either Novak, LPA or Bomar Cut. According to Freedom Ventures..

Fits Bomar cut: 60° x .359
Novak cut: 65° x .495

Kinda get the idea to measure..

This is cool thank you.
I have seen Novaks for sure its not a novak, and since freedom ventures sell LPA, i'm now pretty sure i have a bo-mar cut.
Will measure tomorow and post a picture of it.
 
I'll try these

Man i must be blind when i went on Freedom i only saw LPA cut ones, still want the ed brown instead and they are beveled 45 degrees at the sides.
I reduce my rear sights myself, so it will help me make a symetrical job compared to the STI ones.
I simulate the 2 round corners as found on an SVI absolute zero rear sight ( i once owned that sight and kept all the exact caliper measurments)
 
Try Brownells, lots of Bomar cut sights that will be able to be shipped to Canada as their suppliers have the required ITAR permits with Brownells. If you find one you like be sure to ask for shipping by U.S. Post to avoid brokers fees on items shipped by UPS, FedEx, etc.
