Guns and cars--another fatally flawed analogy.
Your average gun has about two dozen parts. A few of those parts are machined to tolerances that may be measured in the thousandth of an inch, plus/minus several thou. The rest will be stamped.
It may run at 300 rpm (5 rounds/sec) in the hands of Todd Jarrett, etc. For you and me, it will likely run at 120 rpm (two rounds per second)...for seven to seventeen rounds.
Your car has many thousands of parts. The engine alone has several hundred parts, all machined to tolerances of thousandths (maybe ten-thousandths) of an inch. It will run at 4000-8000 rpm for thousands of hours, day in, day out with no failures.
My point? A new Les Baer is a stone axe compared to a new Toyota Camry. Consider how far cars are advanced in the last 100 years compared to guns.
Why is that? Sould be obvious. The expectation of the customer is the driving force.
When I was a kid (60s-70s), cars cost $2000. They had steel dashboards, distributors with points, carburetors, drum brakes, bias ply tires, and were flat wore out by 40-50k miles. Back then, a 1911 was worth $75.
The difference between my parents' 1963 Chevy and my 2003 Jetta TDI is profound. THey basically share nothing but the four tires attaching each to the ground.
The difference between my daddy's Colt 1911 and my Les Baer is likewise profound--mine has an alloy frame, and thin grips....and....ummm. Mine feeds JHPs. Yeah, it has a beavertail. Better sights...better trigger and different hammer.
Not quite the same order of magnitude as airbags, ABS, turbo diesel, radials, 4-wheel discs, etc..
When you get right down to it, a pistol is a very simple machine, and, much like a bicycle, very difficult to improve upon.
