That’s a finishing problem. It has nothing to do with the design. I bought a Springfield Armory and every single cut they made in the metal produced a right angle cutting surface. I had an old Remington Rand that had no sharp edges to it at all. I could fire thousands of rounds through it.
Unfortunately, that’s why Kimber produced a “Melted” look to their guns. I’m still convinced the look was caused by poor manufacturing so they simply adapted a new “look”. It’s not necessary to round off every surface. It’s only important the controls have no burrs or sharp edges like the safeties, the slide grooves and the edges around the mag well.
Take a look at my Springfield on my profile page. It took two hours while watching a movie to remove all the trouble spots. The Taurus had a trouble spot near the grip safety. That’s gone now.
I was thinking of buying a couple of Glocks just to keep under the seat of the cars. I would’t worry if they were scratched up or abused.
That Springfield’s very nice. I carried a nickel Combat Commander for a long time. I now have four Glocks. 8~)
