Hrm..

Rough "back of envelope" design.
To upscale the HP design to .45 ACP,
the grip would have to lengthen 2.7mm,
widen the grip 2.4mm (double stack .45),
increase the slide mass by roughly 0.138kg,
and roughly increase the slide width by 2.5mm.

(No, I've not bothered with the spring balancing or barrel loading design.
This was just a rough 15 minute scratch paper and windows calculator "what if")

HP being JM Browning's evolution of the M1911, it addressed the weaker trigger linkage and more wear prone barrel cam system of his earlier 1911 design.
To my mind, removing the awful French inspired mag disconnect from the HP and upscaling to .45 ACP would make a properly worked .45 ACP HiPower a proper finishing of JM Browning's pistol design work.

Forcing .40 S&W into 9x19 designs is just.. poor 'design by marketing' crap engineering.
A proper engineering upscaled re-design to .45 ACP would be FUN

Design a pistol where the barrel bushing is fixed to the frame, not the slide.....

How about just making the barrel fixed to the frame except for a few mm of linear rearward travel, and changing the locking lug design?

Mechanically simpler, less prone to jamming


(fixed bushing at the slide: high momentum moving slide & barrel, with a tight clearance fixed conic section for a mating surface?  - sounds like a debris sensitive, jam inducing, wear prone part)


...

hrm.. came up with a rather interesting locking mechanism concept, to put between the barrel and slide.
still a delayed blowback recoil design (not gas), but borrows conceptually from the AR stoner locking mechanism.
[Two tubular sections, one rotating, the other linear movement, with a cam pin between, and a delay spring...
Essentially the AR/Stoner locking bolt & carrier concept, but hollow and stripped to the locking/camming section, without the gas section or firing pin)

But making it compact enough for a service pistol layout, I'm not sure accuracy and durability would gain enough.

And for a forward magazine target pistol, there's enough room to put in a completely fixed barrel and proper locking lug design.
Take the magazine forward of the barrel, put the trigger mechanism in the grip area, put the locking mechanism above the physical trigger, etc.

I wasn't suggesting using the AR gas operation, like the Desert Eagle.
Just the delayed unlocking setup, similar to the bolt & carrier.

More interested in designing a scaled up Browning HP in .45 ACP though.
Would be interesting to see how many parts-in-common could be managed.
Frame, slide, barrel, and springs would be different, of course.
Most of the rest should be compatible

You just don't want too much complexity in a pistol, camming parts and so on, especially not in a target pistol - which are usually straight blowback anyway.

They're recoil operated, generally a good bit of gas escapes in the breech, so anything which can clag up will.
The Beretta design is not great, but not entirely stupid either, the Colt AA2000 failed horribly.

HK P7 barrel is fixed to the frame, it doesn't move, same for the P9.

Just buy a P9 if you want a complex recoil system and a fixed barrel.

Complexity is fine, in and of itself.
It is the unreliability and fragility that usually comes with complexity that causes problems.

But, yes, HK tends to get a little overly "German" with their designs.

I'll continue to play with my nice, simple .45 ACP Browning HiPower design here.

Too bad they never put the P7M7 into production.

They made the P9 in .45, I'd still rather have a 9mm P7.

How does your state rate on 2nd Amendment?
Jeff Knox praises 'losers' of Brady Center's national scorecard
Published: 15 hours ago


The Brady bunch has released its annual scorecard rating states based on how strict their gun laws are. The scorecard is a very useful tool to help rights groups understand how their state compares to others on a liberty scale; more points = less liberty.

Alaska, Arizona and Utah have all achieved the coveted Zero Points/Zero Stars on the Brady scale and are now competing to see which state will be the first into negative numbers – which is possible through bonus points. Arizona and Alaska can reach a -2 point score by protecting carry rights on campuses of state colleges and universities. Utah already has such protections, but could achieve a -2 score by adopting constitutional (permitless) concealed carry as Alaska and Arizona have. Idaho, Kentucky, Louisiana, Montana, North Dakota and Oklahoma all came in with just 2 points apiece and all have a real shot at beating the leaders into negative numbers with the right combination of reforms.

The Brady Center released this latest scorecard with much hoopla and heavy breathing, but their own data clearly shows that there is no correlation between gun control and criminal violence. Crime statistics vary widely – from high to virtually non-existent among the 40 or so states Brady ranks as “poor,” while several of the Brady’s highest ranked states have some of the highest rates of violent crime.

As a matter of fact, a full 25 percent of all violent crime in the U.S. occurs in the Brady’s top four states with the most severe firearms restrictions. Of course the Brady bunch and its political allies argue that the tight restrictions are a response to the high crime, but most of the restrictions have been in place for years, if not decades, and they have proven to be completely ineffective at reducing criminal violence.

Violent crime is a result of numerous factors, with poverty, population density, education, social and moral supports and drug and alcohol abuse being chief among them. While it is difficult to prove whether fewer restrictions on firearms results in less crime, it is easy to demonstrate that stricter gun laws do not reduce violent crime – or accidents or suicide.

Even if strict gun laws could deter violent crime in general, that would be outweighed by the immorality of denying citizens the basic right to protect and defend themselves, their families and their communities. These core rights cannot be justifiably discarded based on the bad behavior of a tiny minority of the population.

History and an endless array of scientific studies – and the Brady’s own simplistic scorecards – prove that gun control laws do not save lives, do not reduce crime and do not “protect the children,” despite the hoplophobic rantings of the Brady bunch and its so-called Campaign to Prevent Gun Violence.

Even their name is a lie. They do not campaign to prevent gun violence; they campaign to restrict lawful access to firearms and limit legal firearms ownership. I have never seen any Brady propaganda proposing or supporting initiatives that might actually reduce violence; only an ongoing crusade against gun owners.

The Bradys do serve a useful purpose however: They highlight the threats to liberty posed by hoplophobes and politicians who don’t believe the citizens can be trusted, and they give rights activists a better idea of how liberty is being subverted in various states.

This latest Brady scorecard shows that the vast majority of states are effectively combating those who would infringe on the right to arms. Forty of the 50 states scored 25 points or less, while 31 states scored 8 or less. Reports from state legislatures around the country indicate that scores will be lower next year. Virginia rights leaders are already celebrating an expected promotion to a “red state” on next year’s Brady map, as they will move down at least 2 points from last year’s embarrassing 12 to a much more respectable 9 points. They do acknowledge that they still have a lot of work to do, though, as better than half the states will still have lower scores.

We at The Firearms Coalition would like to express our thanks to the Brady bunch and their cohorts at the Legal Community Against Violence (another deceptively named anti-rights group, which actually compiled the data the Bradys used) for providing us with this valuable information and offering incentives for states to compete in this race to preserve liberty.

you guys are going down Burnzz!

Just found this. It tickles my fancy.

Count me in. Rock River Arms made quality 1911s. I like the OD and tan frame.
