The double action pull of the V2 takes some getting used to. It steadily stacks and stacks weight until the break. The single action pull is very nice. Light with short travel before hitting the wall, and then a crips let-off. The reset is short, audible and tactile.
Accuracy potential seems on par with the SA but I have more trigger time with the SA. Also, the SA having a single action only trigger, it has the advantage of having the same trigger pull each time. The V2 offers second strike capability and the long, heavy first shot capability that many wang in a carry gun.
I've read of a few tricks to improve the trigger pull. changing to Glock Striker springs and trigger return springs, as well as some places that benefit from polishing. I may play around with it a bit. I don't know the previous round count, but I now have just over 250 trouble free rounds through it. The TP9SA is just under 2K of a very mixed diet.
In both pistols I have less invested than in some individual pistols I own. Canik is introducing new models with Warren Tactical sights. They are also discontinuing the V2 and replacing it with an updated version that has the Warren Tactical sights, a different trigger and single side decocker instead of the ambidextrous one on the V2. They are also starting to offer some replacement parts like recoil springs.
