I agree that there are a group of folks who enjoy AND use big bore handguns. NOTHING wrong with that.
But, as noted,, it's about money & the gun is the avenue to that.
But I want to address a statement.
"When the Super Redhawk came out it was made to eat things that would take a S&W apart."
That statement is "kinda" true, but not the real reason it was developed. It came about because Ruger had a FEW Redhawks where the barrel broke off at the frame junction. They couldn't figure out why,, (initially) and the Super Redhawk was designed.
Once they discovered it was a combination of the lube used in assembly, combined with it sitting exposed to air over time,, creating excessive torque damage, they understood WHAT had happened. But by then,, the Super Redhawk was already a success.
I know this,, because according to the fine folks at Ruger I spoke with long ago,, shared that knowledge with me. And why did they share,, well my personal Redhawk was the first one to have the barrel break off. My Redhawk, in .44 Mag,, had not been abused,,, and I had excellent loading records, to show them what it had digested.
Apparently,, during assembly,, a rack of barrels,, would all get lubed,,, then assembly would start. It was discovered that if a lubed barrel was left to sit for a few weeks (during a semi-annual shut-down) the properties changed. When production resumed,, nobody realized this. They would assemble & torque the barrels,, and they would do ok,, for a while. Only a handful experienced the separation like I had.
Ruger strives to produce top quality handguns. The LCP,, while it may LOOK somewhat like a Kel-Tec,, it's not like one. Better engineering,, internal extractor, & overall much better quality. PLUS,, they can build enough to meet demands. Again,, this info comes directly from a few of my conversations with Ruger folks.
Ruger management really looks at the market,, and understand that while they COULD develop many products,, and often much better than expected,, they must justify the expenses of that development, AND show a good profit by selling a LOT of product.
