This is a CZ UB PRE-B disconnector!!!!!
Recently we acquired some used Pre B CZ 75 pistols, on careful examination we were surprised to see how short the reset (Swing forward) was on the trigger, so we took them apart and discovered that the disconnector was different from current manufacture pistols.So we ordered a bunch of CZ Pre-B Disconnectors from CZ UB.
After extensive testing we have found this part to work in all NON Firing pin block CZ 75/85/SP01 Shadow Pistols. Obviously, when the factory added the firing pin blocks to pistols the old Disconnector did not allow enough movement forward for the firing pin blocks to reset.
These may not give the same ultra short reset that one of CZ Customs manufactured and fitted Short reset disconnector will give but be very close and should fit without the need for modification (read below)
Also since it is a CZ B factory part under the rules it should be legal for IPSC and USPSA (Check you rule book)
Please bear in mind there are differences in all the pistols and have a competent gunsmith fit this part and check all safeties are working.
NOT FOR PISTOLS WITH FIRING PIN BLOCKS
CZ 75 Shadow (All Models)
