Comparing a 9mm, most people shoot the "white box" power level, with a 45 is not valid. Much more "banging" going on to the gun with larger calibers and high power factors.
The following are the SAAMI rated pressures in PSI for 9mm and 45acp in both standard and +P ratings.
9mm Luger 35,000
9mm Luger +P 38,500
45 ACP 21,000
45 ACP +P 23,000
Which cartridge has the higher operating pressures again? The 9's look to be running about 60% more pressure. Surely that should eat a gun much faster than a 45acp would by pressure alone.
I'd say theres much more "banging" going on with my 9mm's than my 45's, but then, I didn't need to look it up to know that either.
Which brings me to another thought based on "facts", and not supposition. If the 1911 design were stronger than a glock, it should last 60% longer by pressure curves with the same round count. We know it doesn't, so I've got to wonder why the military found it necessary to rebuild 1911's after 20-30K for 50+ years, and why the Leathams rebuild them after 50K or before through them. The 1911 uses a much lower pressurte cartridge yet doesn't last where the glock runs 100's of K's with a higher pressure cartridge.
Is the 1911 a weak design or what? The evidence clearly does not point to the 1911 being one of the "stronger" designs does it?
