I'm very pleased with my KP89. Although I admit to being no expert on handguns by any stretch of the imagination. It's the first centerfire pistol that I've purchased.
I picked it up to shoot, and shoot, and shoot. I don't use it for CCW or anything of that nature.
It took me a while to get used to shooting a centerfire pistol. Lot's of advice from my buddies (and practice) really helped out in that.. Once I got the basics down, I've found it to be accurate, it shoots at least as well as I do.
I'm still in the learning stages, to be honest I haven't done any type of group measurements. I would say that slow fire at ~20 yds they all wind up in roughly a 4 inch circle if I concentrate and keep the first DA shot from being a flyer. This is limited by my shooting ability, not the guns accuracy potential. (to be honest I shoot the KP89 better than I shoot my MKII).
For some reason it really doesn't seem to like CCI Blazers, and accuracy suffers. It does great with the 100 round wally world bulk packs, and the "reclassified" gold dots.
I'm quite happy with the fit/finish, and don't find the gun to be boxy, I actually like the grip (I have medium sized hands). That of course could be because I don't know any better
After roughly 500 rounds or so I've yet to have any type of trouble, nothing bad to report there.
If I could change one thing, I would have picked up the decocker only version (mine has the decocker/safety).
My only real complaint is I wish that I would have waited a few days, as I could have taken advantage of Ruger's current $40 rebate on P series guns, which would have made a great buy even better.
