Old school thinking. There have been recent significant advances in both projectile and handgun technology. Any gap that ever existed has essentially closed. His opinion is based on a slice of the data pie. Marshall and Sanow suffered from similar blinders. Ellifritz has pretty much closed the book on the handgun 'caliber war'.I gotta know.... Why no 9mm?
John Helms, Larry Mudgett, Uncle Scotty Reitz - legends. What they have forgotten about gunfighting most will never even know. All three were decorated LAPD Officers.
John Helms was S.I.S. after SWAT. When those guys spoke, we would sit around like disciples listening to Jesus.
Any serious student of the handgun should own Uncle Scotty's book The Art of Modern Gunfighting. But be advised, once you read it and follow Uncle Scotty, you won't ever want to carry a 9mm handgun again. Regards 18DAI
