I just got mine, put 400 rds. through it today. This is easily my favorite pistol I've ever owned. I ran all kinds of different factory ammo (The worst I have), and 3 bullet weights and OALs of reloads. I had 3 stove pipes on my 147gr reloads, but I limp wristed them, because the recoil from my midrange 147 loads is so light, my instructor and I were calling them Airsoft. It's REALLY easy to do a 2 shot burst in 1/3 of a second, and have them land in a 4 inch circle at 7 yds.. This gun shoots so flat, I had to adjust for a few minutes to get used to it. The medium and large backstraps change the grip shape to something close to a VP9 or Walther grip, I thought that was neat. The slide gets hot faster than my other Caniks, but it cools down in seconds because of the chrome coating (MUCH faster than any of my other Caniks, HK, Walthers). I'm guessing that's why they used it. Even after 9 mags in 2-3 minutes, it never got near too hot to touch, not even close.
The stare factor at the range is cool too, 5 ROs and 4 shooters asked me what it was, and how much it costs. Pictures don't do this thing justice.
Also, the beavertail is hooked/lower more than the Mete pro, which was my favorite Canik until today, because of that enhancement they made to it.
I hope they stop making every new release better, it's starting to cost me.
My instructor already has 3-4k rds through his, no hiccup after 50. This is the tightest slide I've ever seen both it and the trigger need 50-100 rds through them to make them super smooth.
The mags pop out faster, and the trigger is slightly more crisp than the polymer lowers, I imagine that has something to do with it being steel.
The gun is so well balanced, the additional weight was undetectible to me, after even 200+ presentations fron the holster. No weak spots on this gun, it's a homerun. If you do buy one don't change anything, there's zero need. If it isn't everything I say, you gotta look at how you're shooting it
EDIT- Oh yeah, forgot to mention that the backstraps/sides are like smooth grip tape on a skateboard. Very comfortable, but the medium and large grips grab so much, your technique needs to be good, pull it straight up. I like this because it gets hot as hell here 4 months a year, and I shoot with sweaty hands the whole time.
