Gege Euro Cylinder AP1000, 6 pins and all are security pins. GeGe locks are up there with my favourite locks, they are challenging when lockpicking and have really nice tolerances. Meaning that even if you set or over-set a perticular pin, you run a high chance of dropping keypins you've previously set. Making this lock a bit of a nightmare to pick. In this GeGe cylinder it boasts 2 crimped ended driver pins ( which Ive never come across before ) and 4 very deeply serrated ones too, that coupled with the counter milling on 5 of the 6 chambers of the plug creates a very challenging picking process. Overall Im very happy how it all played out and that Ive one less lock in the naughty bucket for lock pick.
