I've actually owned two (not at the same time) 2075s in 40 S&W with alloy frames. The first was sent back (1/2010) for repair because the slide would lock in the open position when the magazine wasn't empty. When I got it back it still would do that on occasion but now I was suffering misfires and FTFs. CZ took the gun back again (3/2010) and replaced it with a new one.
The second gun I carried for a couple of years. Took it everywhere Texas to Montana three time and Texas to Florida and pretty much everyday carry. Initially I would try to go to the range every two weeks and then slacked off to once a month. I still would get FTF and the gun had an annoying habit of not locking open when empty, but would usually function flawlessly for the first two magazines. This made it okay because I rarely carried more than one spare magazine.
I tried all the different "sizes" from 135 grain Federal to 180 grain Speer. I decided I preferred the 165 grain round because it offered what I thought was the best of size, velocity and energy. I really liked the Hornady Critical Defense round, however, my 2075 did not. When the gun had a problem it was always the third round seemed like but the Hornady would fail to feed often. It was just a matter of smacking the butt of the gun to get it back in "gear" but after a while it kind of gets in your head because you're expecting it and then your groupings go all to heck.
I started reading around looking to find some sort of fix. I found the comments in CZ forums about polishing up the feed ramp and tried that. I noticed some improvement but then the barrel broke (2/2012). I'm guessing I had somewhere between 1800 and 200 rounds through the gun at this point.
CZ took the gun back and kept it for about three weeks. I got to thinking that part of my problem might be fixed with new recoil springs. I bought a new assembly but the springs were always out of stock. I finally called the parts department and pleaded my case and they sent me two sets of inner and outer springs. CZ's customer service is outstanding.
When I got the gun back, the barrel had been replaced and it had evidently been worked on and I also noticed the lug wasn't as boxy, so I'm thinking my troubles are over.
I've long suspicioned that part of the reason the gun would malfunction is that the gun would overheat and between the alloy and the steel would swell. I could be talking through my hat on that but I noticed the gun would malfunction and if you set it down and let it rest and cool, it would work fine again until you ran another fifty rounds through it and it got heat build up. This is also why I decided early on that when I take the proficiency test for my CHL renewal I'd be shooting my Colt Commander. And that's a heck of a thing to be thinking about your carry gun.
At any rate I took the gun and my new barrel to the range (I posted a picture of the target in the range thread) loaded it with a number of different grain bullets and gave it a whirl. Once again it was flawless for the first two magazines and then I started having problems. Usually of the FTF variety. The slide locked open when the gun was empty and that was an improvement. About 100 rounds fired.
The second trip to the range I installed the new recoil springs and the gun failed after 39 rounds. I've noticed over the months as my frustration grew that so did the size of my groupings. I found myself expecting it to fail. I bought a Colt Combat Commander circa 1982 and took a couple of boxes of ammo to run smoothly and the only problem was a broken slide lock about 3 years ago. I decided after two and a half years that this was not going to work for me and I put it in my range bag.
I rented a range gun. A S&W M&P 40c. I had tried the subcompact Glock 27 and 36 prior to buying the 2075. They were fine but I suppose I wasn't ready for a "plastic" pistol. My first effort with the S&W at 5 yards was pretty decent for a range gun with reloads.
The decision was made.
I got the 2075 out of the range bag to clean up and when I got around to the from of the slide I was in for one last shock. A stress crack.
So, I called CZ and told them my problem and recounted the story above. I told Jon that this gun just wasn't working out for me. I asked if they would send me a different model and he agreed to send a P06.
I really liked the way the P06 looked, but after my journey with the RAMI I traded for a S&W M&P (which I refer to as metal & plastic) 40c.
The only reason I'm not bitter is the great customer service of CZ. Not one hassle.
I do have a very nice unlined custom Hign Noon holster, 3 nine round and one eight round magazine for sale watch the barter thread if you're interested.
