Need some information on Thompson rear sight

clockman2001
I have recently bought a 1927 model Thompson A-1.At 50 yards it is shooting 5 inches to the right and a foot low.With no adjustment for windage how can I correct this?
Does someone make a drop in fully adjustable rear sight for this gun [?]
If anyone knows please e-mail me at sjflynn@sbcglobal.net
Thanks..............

    You can fix the elevation by filing the front sight down.

    My border collie is smarter than your honor student.

    Hate to point out but you do have an elevation problem, if you are shooting a foot low at 50 yards.

    Indeed The originals Has aan Adjusablke lyman rear sight, they go for over $300 when you can find one and they dont drop iun, they rivet on. The early Auto Ord models had a repro lyman adjustable on them..Perhaps Kahr has those in stock ..Gun parts copr has the components (nd the rivets) .,.you can assemble one for around $125.00 total ..http://www.e-gunparts.com/productschem.asp?chrMasterModel=111ZzTHOMPSON 1927A-1
