See pic below of my Trojan below. LPA TRT54FU07 (Bomar cut) did not fit. Supposedly in 2014 or 2015 STI went to LPA for sights for the Trojan.
I read somewhere that the LPA TRT54FU07 that is used on CZ 75 Tactical Sport would fit. Trojan breech face to cut is 13/16".
ANY HELP FOR A NEW SIGHT would be appreciated. Fusion Arms, Hutchinson, Kensight - no luck there.
