My question is, what's the difference between my cheap handgun compared to a high-end model?
I'm no competition/sports shooter, I just shoot for fun! Other than that, the weapon is for home defense. Is there really any need to have a ridiculously expensive pistol?
Just like with anything else, it all starts with the raw materials. Some use top grade materials, machined to close tolerances and then had finished for fit and operation.
Others may start with the same machined parts, or substitute "investment cast" parts. To remove any burrs the parts in a cheap firearm are usually just tumbled rather than hand finished.
Take apart a Sig 9mm and compare the internal parts with a Hi-Point. The differences will stand out like a sore thumb.
Some might say "so what, it still goes bang". Yes, but will it do so every time? For a long time?
Keeping the cost of a product down, regardless of whether it's a Toaster for the Kitchen, or a Firearm for Self Defense, something has to be left out. Cheaper parts and less hand finish time are often the first to be targeted for savings.
All this said, there is a point where all the extra "fancy" doesn't add to the quality of the product. Likewise, the big "Names" have big budgets for promotion and advertising. All that expense shows up in the price of the firearm.
When deciding on whether to buy a cheap firearm or spend more money, ask yourself what you are willing to pay for reliability. In Self Defense scenarios there is no second chance. You want a firearm that has a track record for reliability, period. Doesn't have to be fancy, or one that impresses your friends. It just has to be work when literally, your life depends on it. Is that worth saving a couple hundred bucks? Or is it better to go with something that has been tested, over and over, not just in the factory, but in real life scenarios?
For me, I've always gone for the "Ford/Chevy Sedan" rather than the "Ultra Economy or Exotic Sports Models" when selecting something for SD Carry.
Cheap or High End? What's your life worth?
FWIW, Taurus has an interesting history. Their first firearms were developed using Colt, S&W and Spanish firearm features. At one time Taurus was owned by the same group that owned Smith & Wesson with lots of tech info shared. Beretta built a factory in Brazil that and eventually sold it, tooling and all, to Taurus. Maybe that's why they have a pistol that looks so much like a Beretta 92.
Overall, I have seen lots of Taurus pistols that are right up there for quality and reliability.
