I haven't said either the Chiappa is bad, or the KSG. The point - which I haven't missed at all - is what guns have been flops. I define that as having been introduced to the market to sell - and which aren't. So much so they can't keep market share by sustaining appreciation for what they do.
Once past the initial group of interested buyers, guns that don't maintain continued sales and make a profit are flops. We currently see Chiappas and KSGs plentifully on the shelf. Something about a lack of sales makes that happen.
A local oriental buffet makes a lot of sweet and sour chicken every night, the octopus, not so much. Like some firearms, I have preconceived notions about octopus, I'm not grazing there. Guns can be much the same, the visual presentation and type of marketing can turn off buyers who could be fans - if they would just try it.
I was looking for a small 9mm SA pistol when I found the EAP and SIG P938. Visually, the EAP wins, hands down. Price wise, the SIG got my money. We can and do compromise somewhat to get the features we want on a firearm, but some can't and won't. Hence my discussion of the KSG and why it's not going to make it.
The Chiappa? Haven't cared. I don't shoot revolvers. That class of firearm isn't likely to ever be in my possession, they don't have the features I want. Doesn't make them bad - I just don't like the flavor. Broccoli. Chiappa now has to sustain sales to keep from being a flop. The company producing them went so far as to make fun of us "tin foil" wearers. We have a concern over the RFID chip that can ID the gun is in the immediate vicinity by a scanner - and so much for carrying it concealed at that point. If it's just you walking down a corridor, you are made. No, the chip doesn't say much of anything other than a SN for logistics purposes. But responding - at all - is the key item. A simple transponder system set up in the entrance of a lot of businesses going off every time someone passes by means you don't carry "concealed," even if it's legal. If it's a government detector, it then goes to statutes over interpretation on the issue of not disclosing who is a licensed carrier and who isn't.
Is your Chiappa going to set off an indicator every time you pass the entrance of a Big Box discount store? I don't care how good the gun is, would the average buyer want that, and the chore of removing it, which may constitute a violation of warranty with some makers in the future? These are factors which already influence the sales of the gun on the open market, and why some won't purchase them. If that resolves into pattern of sales that won't make profit - flop. All because of the chip, not the engineering. If anything, the engineering was a positive and I considered it at one time. Not now.
It's simple, we buy or don't buy based on our perception of what constitutes an attractive and reliable firearm. Some buy on brand, others discriminate because of it. Regardless, the overall impact is to continue buying them - or it's a general boycott based on some perception about the gun. Pricey, politics, or personality, the community at large won't shell out the bucks.
Take the HK P7 series - it never was really appreciated in America when produced, and the rising price of a new one cut off a lot of sales. Yet, now, it's a highly valued collector gun selling for a darn sight more than when new. So, it was nearly a flop before, but now, it's hot. Perceptions change, same with the AR - nobody much wanted one in the 70's thru early 90's, now, the guns we preferred then are off the market and long gone. The AR is the market leader and still growing. About all that saved it were government contracts - the open market considered it anathema, the poodle shooter that poops where it eats, the jammomatic that will get you killed. Not so much now. It survived the initial misinformation long enough that the real attributes are now appreciated. People found it it wasn't broccoli after all, just the same as shooters of the Chiappa appreciate it's not like a revolver dynamically.
Seen a Remington ACR at your local gun store lately? Nobody complaining about it being broccoli. But, if the current trend continues, I doubt it will survive a change of ownership if and when Remington sells. Unlike the Chiappa and KSG, the gun had an adoring fan base - who were stiff armed at the counter by the price alone. It was the opposite of broccoli, but, it's still a flop. And you can find them all over the gun auctions, there's a reason for that. It doesn't take weird engineering to make that happen. Just a Corporation.
