Unique 5903

That's Not , " homemade " , that's HybraPort ! Seriously , once upon a decade , this was a serious thing , and had a modest degree of sucuess . Genuine HybraPort had a complex venturi shape , knockoffs were straight or simple conical .

Unusual on a S&W , typically on 1911 patterns , both full size and compacts .

It massively reduced recoil and purportedly made muzzle flip near zero .

It did reduce velocity , but not as much as you would think , maybe 75 fps - ish .

Are you saying someone actually PAID someone to mutilate this pistol??

Wow.

This has Bubba written all over it.
 
Again, greatest inventions come from Concepts.
Dare to be bifferent .
If you have an idea that might make a pistol better go for it.
 
Hey y'all! Thanks for your patience! Been really busy over here but as soon as I get some more time I'll submit more photos for examination.
 
I might would pay $100 or $200 for it, just for the frame and what ever parts could be salvaged, but who knows what the guy did to the frame. I don't really like that safety lever. The hammer has been molested. The magazine floor plate, I kinda get the idea but of seems like a 90's attempt that went way overboard. The only thing that the guy did that I like, is it looks like it might have an Ed Brown mag release. Of course it has Pachmayr grips. That is the cherry on top.
 
I finally found this item via internet search. It was supposed to be the next best thing to oxygen in the early 1990's. I thought it was insane.

Obviously this was very successful - NOT!


Yup , this is it .

The physics are sound , and it does work as designed. This is back in the Era when Compensators were all the rage ; and there was a cottage industry of 'smith's offering variations of " Carry Comp " packages . Think shortening the bbl and slide ; and adding a comp of similar length , and the more ambitious ones contouring the comp to match the slide profile .

The goal was pistols that fit into standard holsters ; but with greatly reduced recoil/ muzzle flip . Sub Sub variant was Officers length slide , with a contoured compensator to bring up to Commander length ; or Commander slide up to 1911 length .

Schulman's better mousetrap was keeping longer length bbl ; adding ports on top .

In the '80s these things weren't fringe .

What he said

From the tone the vast majority of the posters here sound like they've never seen a gun older then 10 years.

Way back when, before Brownells, Midway USA or the internet most gunsmithing was local. A few, very few, big names did exist, Kings, Pacmayr, and Magnaport among them.

Mods like this were way way more common then people today think and DID work. Just think about it, before bolt on mag wells for 1911s smiths would heat the bottom of the frame and drive a wedge in to flair out the funnel. Sounds primitive to us today but it was a high end custom job 50 years ago.
