The first article addresses issues found mostly on early production guns - by the time it was written (2004) the Mk.III Hi-Power was already 15 years into production. For example, the cast (later on - MIM) parts of the firing mechanism in today's guns are quite hard actually.
Any, and I do mean any, guns that are used extensively with 9mm NATO, or +P ammo will have a shorter lifespan. And that's a simple fact. Some will deal with it better then others, but they will shot loose earlier compared to guns used with standard pressure ammo.
On one of our local shooting ranges we had a couple of rental gen. 2 Glocks (17 and 19) with cracked slides - just bellow the rear side of the ejection port. Those guns were used only with 115/124 grains of standard pressure FMJ. Should we say Glock sucks, don't use +P ammo in it? Of course not - stuff like that happens when you put thousands upon thousands of rounds thru a gun.
Yes, the Hi-Power is not the best and toughest uber-pistol out there, but this: "...even a few magazines of +P will upset the locking lugs." Com'on now - do you really believe that? Sure, the BHP is not as tough as a Sig P226, but it's not a "Saturday night special" either.
NATO spec ammo is not always what folks think it is. The BHP has run on NATO spec ammo from the inception of NATO.
A good deal of what Ayoob writes in his 10 year old article article is incorrect and hyperbolic. He damns with faint praise. He gets a number of things wrong, too many to go and strengthen out. This article has been the source for many mistaken ideas on the BHP over the years as Mas Ayoob is a prolific and respected gun writer.
"From Venezuela to Great Britain; I've seen quantities of broken Brownings in government arsenals whose slides and frames were cracked by the brutal hammering of 9xl9 NATO ammo. +P and +P+ loads also seem to be contraindicated. Listen to Bill Laughridge, who said to me, "Tell your readers in all caps, DON'T USE +P IN HI- POWERS! It's been my experience that even a few magazines of +P will upset the locking lugs."
(I'm not gonna ask how Mas Ayoob got access to government arsenals in Venezuela and Great Britain and points in between, I don't know him and I'll take his word for it. I don't figure that finding broken parts of guns, M-16s, Glocks, M9s, etc., in government arsenals, a place where guns are rebuilt, is all that odd though.)
Ayoob quotes Jeff Cooper on the BHP, the quote is that
"the only problem with the gun is it'a caliber". Nothing about it's durability. I trust Cooper's opinion on this.
The Hi-Power, as Mr. Camp said, will not have it's locking lugs round out with "a few magazines" of +P ammo. Camp's writings on the Hi-Power and it's durability have the weight of experience and competence behind them and are a better overall take on the gun in my experience and opinion.
The BHP is like the S&W M19 and M13. They are excellent fighting handguns so long as you take care of them and don't treat them like an N frame or L frame. The BHP is one of the great fighting handguns of the last century, and is still that today, but it's not up to the rigors of modern competitive shooting in the volume many shoot today. For that a stronger gun is needed or the patience to upgrade parts of the BHP more often. I think that's an honest take.
