Ok. Here's the deal. I know, and agree, that more likely than not an accuracy issue is going to be shooter rather than firearm related. I also know that even people who know that, think that they're an exception. Well, I'm no different. Here's the thing:
I bought the Kahr after being a Sig only guy because of it's size and I didn't like the SAO 938/238s. First time out, the trigger took some getting used to, but it wasn't that different from the first round DA pull from the Sigs. My wife and I enjoyed the first time out with it immensely and both of us did well shooting at 5.5" Orange Peel targets from CCW distances.
Since then, I feel like the accuracy has only gotten worse. The only change that was made to the firearm, other than being broken-in, is that I replaced the front sight with a night sight. Recently, I took it out to test some reloads and couldn't hit anything. I assumed that maybe they were just too hot and that was the problem, but today I took it out with WWB and couldn't hit an 8.5"x11" piece of paper from about 15 ft away.
By the way, I hate the bar-dot style sights so I just line the top of the front sight with the top of the rear sight. I emailed Kahr to ask if the Trijicon front sight in conjunction with the standard bar rear sight and they said: "We are not sure if the current combination of sights would be an issue or not. the height of the Trijicon rear sight is the same as the height of the standard day sight."
I bought a Lasermax for it as well, but haven't really tried to use it yet because I want to get it worked out with the irons first.
Also, I don't think it's that I've declined in general as a shooter, I'm still doing well with every other firearm we own.
Any suggestions?
