Both hammer and trigger would be much wider if they were target. The grips are of course but it would be very unlikely to be original to the gun without target hammer and trigger
Standard hammer and trigger. The target stocks are of a style that is much too late for a Model 17-2. Dash 2 production ended in late 1966 or early 1967, 10 years or more before the speed loader cutout started showing up on K frame target stocks.
Target hammer spurs are 0.5" wide. Originally target triggers were also 0.5" wide but to make them no wider than the trigger guard they were reduced to 0.4". The service trigger in the 17-2 that you are considering is 0.265" wide.
While I would install the pictured wood Target Stocks within seconds of buying that 17-2 they are obviously not old enough to pass for original.
The revolver pictured does not have a target trigger or hammer. As mentioned above, the target triggers and spurs on the hammers are at least twice as wide as those pictured. The wooden grips are target grips.
Am I right in thinking that if I'm looking for something for bullseye and not just plinking that I should wait till I find something with the target trigger and hammer? They are noticeably better? I'm a 288 average shooter with my Pardini so don't want to outshoot the gun
This M66 from 1983 has the target trigger and hammer. . .kind of hard to see in the picture I have on file. You will know when you see a gun with these. They are huge. The trigger is smooth too. I see a lot more target hammers than I do triggers. Many of my Smiths have the TH. Few have the TT. I actually like them. They add a lot to the appearance of the gun to me.
Here is a Model 14-3 SAO with factory target hammer and trigger. You can see how much wider they are.
Note: the stock target trigger for a Model 14 was grooved. Combat triggers were smooth on the face and also wider than standard. I have one on another revolver but don't have pictures of it.
While not in the same class as you I shoot bullseye regularly with a model 17 with standard hammer and trigger and do just fine. I would suspect with the learning curve you could expect your scores to dip a bit when switching to a revolver but will bounce back quick. Any functional condition 17 regardless of having tt/th or not is easily capable of cleaning a national match course
