I have had several that people have ragged on. The first being my Dan Wesson 15-2 I bought when my awful first gun ever Taurus 83 went on it's first of two trips to FL to get "fixed". Never happened, even after the second trip, they never fixed the totally messed up barrel, so I got rid of it. People I knew, including a former NYPD officer, claimed they were "No good", and that the Taurus was better. I stopped taking advice about guns from that point on. I had one problem with that gun, the previous owner had clipped the mainspring to lessen the trigger pull. Light primer strikes galore. A new spring, and it was great. I had that gun many years. A few years after I stopped listening to the former NYPD guy, I ran into him, and he asked if I still had it, I had three, he was shocked. Even more shocked when I told him he didn't know what he was talking about when he said they were "no good".
People have made comments about my Astra guns too. I've had an A60, an a75, 2 A80's, an A90, and two A100's. No problems with any of them. They hit where they were pointed, and the A75 shocks most shooters with it's great DA trigger, very smooth and fairly light. I only sold off the others because I needed money in a hurry, the last A100 was bought at a great price and sold at a pretty shocking amount.
The last ones I've had comments on are my SAR and Canik guns. Some of it is the nonsensical political stuff, but other comments seem to claim bad steel (I've seen nothing on YouTube or any forum to back this up), or they aren't "Accurate". That's not true either. They are all well made, and IMHO the CZ clones are pretty much equal to the "real thing". Turkish guns in general seem to be all well made.
