Let me jump into your discussion on sights this morning for Caniks . First let start by saying please don't be offended by what I am going to say. I have probably changed more sights on Caniks and now Sar products than any one on this forum or anyone in the US. I started customizing these pistols well over two years ago when they first hit the US markets so I have quite a bit of trigger time on these pistols. I have also owned or currently own one of every Sar and Canik that has been available for sale.
Second this experimentation on there pistols led me to a good working relationship with Dave at CGW, he would never steer you in the wrong direction ,but you must listen and pay attention to what he is telling you, don't here what you want to here.
Third in most cases the problem is not the sights it is the stiff triggers. Unload your pistol and post a target on the wall seven yards away. Test your trigger in both double action and single action mode. By testing I mean pull the trigger in single action and watch the front of the pistol when pulling the trigger and see what direction you are moving it in. The slightest amount of movement can translate to a number of inches off the center at seven yards. As you increase your shooting distance out to 25 yards that movement of the muzzle in a particular direction can translate easily into 6 to eight inches off at 25 yards. Repeat the test in double action and you will move the muzzle even further.
To shoot good groups with a Canik or Sar in stock configuration you must master the stiffer triggers. Sight upgrades are only going to do one thing and that is to improve overall sight picture. Now we have put thousands of rounds through 2 Caniks and 2 Sar pistols last year shooting IDPA so we have worn the triggers in nicely ,but they are still stiffer than our custom Caniks which have nice buttery smooth upgraded triggers from Dave at CGW. The custom Caniks shoot wonderful double tap groups easily into the head of and IDPA target and usually the group size is an ich or under for a rapid double tap. Accuracy overall beats our stock Caniks dramatically.
So test your pistol while unloaded and see what direction you are pushing the muzzle when you are pulling the trigger. Now improving sight picture is not a bad thing, the stock sights get the job done ,but there is always room for improvement. As we get older like me 54 the eye's sometimes need some help. In my case I neeed a wider rear sight notch and a green fiber optic front sight so I can easily pick up a fast sight picture for IDPA so improving sights is not a bad thing. Last sometimes we actually find a pistol that does not shoot to point of aim so some tinkering with front and rear sights is required. In most cases that I have encounted it is a trigger issue not a sight issue. Again I do not wish to offend anyone I am just trying to help solve the problem, but it must be diagnosed properly.
