Im searchin for a adjustable or even a plain replacement rear sight with a set screw for a Cannick 55 / Triststar 120. Since my rear sight isnt the tightest fiting and likes to creep. Id also like to know if the CZ 75b rear sights are an exact fit in this respect. I searched the web today and could not find one to save my life. With the exeption of Cajun Gun Works nothin against CGW but their piece is alittle too costly for me and I thought Id check before I commit to such a unit. PS is there even such thing as an non permanent adhesive for dovetail sights . The factory rear sight works fine when lined up correct at 7yds it will put em all in the same hole or darn close after my arms tire. I was hoping I could get one of the many CZ after market ,hell even factory sights to fix my pistola.
