Things I liked:Ingenious time proven design, compact, quality made, very reliable. Things I would have changed:Rear sight is OK, but definitely could be improved. The pistol is very left-hand unfriendly and LH version does not seem to be available. If left hand grips are available for the Alecto, why not for the Tempest? What others should know:It is very easy to mount Mendoza micrometer rear sight on a simple 11 mm rail made from a piece of steel angle. The sight is inexpensive, accurate, and fits perfectly. No modifications to the pistol or the sight are needed. It is much easier to cock the pistol if you position the hands as recommended in the manual. It seems quite awkward at first, but you get used to it very quickly.
Things I liked:Price is hard to beat, solidly built, positive clicks. Things I would have changed:Not much. Maybe engrave LR and UD directions? What others should know:It is not difficult to install this sight on Webley Tempest air pistol by making custom 11 mm dovetail rail from a piece of steel angle.
