[gunut45]

That is sweet! I have never had a chance to shoot a 10mm :(

[Mark71]

Very nice BIG_CHRIS_304! I have been waiting for the video since you posted your first project. So whats your next project?
Thanks

[Andrew_Dawson]

GREAT VID CHRIS THANKS FOR POSTING IT! That 10mm is a BEAST!

[neo2233]

Thanks for the video.

P.S Caps does not bother me.

Arizona rules...........

[MBSL]

Glad to see I'm not the only one that took on the 10mm USP conversions.

[riker1]

ME WANT !!!!!!!! ME WANT!!!!!!!!!:59:
Opps sorry
me want! me want! shhhhh

[piebiter]

Awesome Big Chris...thanks and keep them coming!

[orfeo]

Too bad HK doesn't make a drop-in 10mm conversion. I feel sure that they would sell a sh**load of them.

Thanks CHRIS for the video. :)

[ParChaser]

It won't let me use the link. I want to see. Help me. It asks for a password.

[Phines_Photos]

so was that a .40 or a .45 before the conversion?

[ronin_asano]

must have run out of bandwidth, the video didn't work for me.

[loupav]

Thats awesome!

[Slingblade2006]

I think they use a .40 for the conversion. 10mm and .40 are the same diameter. I am curious on what mag they use for the 10mm round.

Ya gotta be kidding me! Eleven rounds ain't a test, sorry kiddies!

You'll note no chronograph readings nor platform longevity because the USP will not hold up to the 10mm nor full power .40 S&W (exp 135s@1500fps)

[rext]

Thats cool

[TobyHKnut]

I wish more people would make that conversion LIKE H&K lol That's awesome THANKS! I bought the Delta Elite when it first came out..one of the guns I will never get ride of. It's such a great round...bravooooo!

Are you listening H&K??? Do it.....Do it

OK, so wheres the proof that the USP will not hold up to these? I am interested because I like .40 and love 10mm.

[twisted954]

there is a measure of concern around the 10mm conversions...now Im not saying one way or the other, but for those that ask Im throwing this out there. From what I have been told, the 40 cal is not a "fully supported" chambering. Im trying to chose my words wisely here. The term "fully supported" refers to the pistol being designed specifically for a certain ammo type, ie: 10mm, 40 cal, 9mm...guns that are designed for a caliber are typically fully supported and can handle all types of loads with reasonable reliability, ie: +p +p+...however many handguns are modified versions of guns that were originally something else...sometimes this means very little...sometimes it means alot. For example, a walther p99 40 cal is not technically "fully supported" because it is a 9mm gun with a heavier slide. Now from what I was told, the lack of 10mm backing relates to the 10mm having more punch than a 40 cal and so there is concern that the gun's reliability and longevity might be compromised kind of like only running 40 cal +p+ through it all the time. I dont know this to necessarily be the case, but it is the reason why there is no factory support for the conversion nor a drop in kit.

In either case, it is cool!!!

[twisted954]

oh and ninja, I personally have no proof to offer in either direction. i am speaking on hearsay and theoretical information that has been either handed to me or inferred on my part. The problem with me and HK is once I have invested the money to own them, I don't actually have the heart to beat on them. Someone else might be able to clarify with solid numbers or something and they proof might even contradict what I said. I havent done a 10mm conversion and actually havent been around one at all. I am just trying to answer the mythical question "why doesnt hk make a drop in kit like this because it is actually rather simple" with a probable theory.

[straightgrain]

While I will stipulate to 11 rounds not being a test...

I'll need some kind of citation for your assertion regarding the USP platform not able to handle "full power" .40. If this is, indeed, the case, HK has one heckuva liability issue on their hands.

[faris13]

I don't see why the USP .40 would'nt handle "full power" .40?? The USP 45 has the ability to handle .45 super so I don't see the problem. I'm sure those who know more will chime in.

[ironchef]

I believe the USP's design is based on the .40 platform. With that in mind, I would hazard a guess the engineers and designers at HK would have taken into account the "full power" of a .40.

The USP 9mm came afterwards based on the .40 design which made it "easier" for HK to dial down to a small caliber (and not vice versa like most other companies, hence problems those companies encounter later on). The USP .45 design is independant of the 9/40 hence the larger frame/slide/parts etc.

You were told wrong. An HK 40 cal barrel is 100% supported. If you don't know what you are talking about, or can't vet your source, don't pass on garbage. A picture is worth a thousand words....

In either case, it is cool!!!"Fully Supported" has nothing to do with calibers and guns that are designed for a specific caliber. It refers only to how much of the shell casing is expose @ the feed ramp. The above post is a perfect example of a fully supported USP barrel. Below is a picture of a glock barrel that is NOT fully supported. Again it has nothing to do with calibers a gun was designed for.

http://www.hipowersandhandguns.com/Critical%20Look%20at%20the%20Glock%2017_files/image018.jpg

[bspring]

Glocks are reported to have an unsupported barrel. I have a Glock 20 with a Jarvis barrel, very accurate; but still can't stand the long creep even with all the trigger mods made...3.5lbs trigger bar, etc.

I have a USP .40 and thinking of a 10mm conversion, did rechamber the stock HK barrel or use a Jarvis? Which STI mag was used, a stock length or extended?
I also assume a stiffer recoil spring was used, 16lbs? Did you also mill out the ejection port?

Thanks,
Bill

Well thanks for the clarification. That was exactly how it was explained to me so I passed it on and, to be honest, I didn't know the 40 came BEFORE the 9...the trend with several manufacturers has been the inverse, meaning 9 then 40, in the past which is the reason why I have been following the thread because I knew someone who knew more would chime in. I will try to dig up the source of my mis-information but I will have to scratch my head on it. This was gathered some time ago and, to be honest, I just cant recall exactly where I read that. Your explanation seems to make much more logical sense, though.

Okay...believe it or not, I sourced up the exact article on the first try with a quick search...three years ago I was toying with the idea of picking up a steyr m40 A1 and was searching for a review and I came across an article that debated the "fully supported chamber." The reviewer had actually made a reference to a "well supported" chamber which actually confused the explanation. The article speaks about handguns that start life as 9mms and then convert into 40 cal. The round is obviously larger which necessitates an intrusive feed ramp and possibly an oversized chamber. Weapons that start out as 40 cal have no such needs and can be design appropriately from the get go. So it seems I actually congealed a story incorrectly over time...glad this happened though cause it gave me a chance to brush up.

WTF is full power .40?

Commercial .40 is loaded very close to its maximum pressure spec as it is, so once again, please explain to me what full power .40 is, and when you're done with that, explain why you have enough credibility to comment on something you haven't done and obviously know nothing about.

Ever wonder why you never see "+p .40"?

WTFO?

[twisted954]

Im not even sure what WTFO even stands for, but how about you just put on your special helmet and go to your happy place.

How come every time there is a caliber conversation on here, people get all uppity...lol...calm down

[Cadillac Johnson]

Ever wonder why you never see "+p .40"?

You know I've wondered why they dont make +p .40sw ammo.

I always hear how it's loaded at such a high pressure, and this and that, but it's the same as 9mm, and lower than any +p 9mm or .357sig.

You would think there would be some room to make a +p .40sw. I dont see why a .40sw couldn't be loaded to a higher pressure. The .357sig makes the best argument for why it could be possible. If the .357sig can handle 40,000psi, why not make a .40sw loading at 38,500psi?

SAAMI SPECS:

9mm - 35,000psi
9mm +p - 38,500psi
9mm +p+ - 40,000psi??? Im just guessing here..
.357sig - 40,000psi
.40sw - 35,000psi
10mm - 37,500psi

No real reasoning behind this post, other than I always thought it was rather curious.

I can answer your questions, both of them.

I will answer your second question first. People get all uppity, your adjective, because we get tired of moderators who let questionable people like you have access to the forum and post patently stupid replies to a good thread.

Now, for my answer to your first question, modified phonetically, which I am sure will earn me at a minimum, a week in time out...

WHAT THE PHUCK OVER?

Herr Gefängniswärter, please be kind.... Take this portion of a PM he sent me into consideration when computing my sentence:

"To be honest, a lot of this stuff is beyond me but I like to converse about it..."

[Germanic]

That's a cool conversion. Glad it's running well for you. I heard that Bruce Gray may be offering a 10mm conversion for the USP. He is already in the middle of offering a 10mm conversion on P220STs.

On a side note, I do recall the first American Rifleman article on the USP in .40S&W. During their T&E, the USP they were shooting developed a broken locking piece on the guide rod while shooting some 135gr. Corbons from what I recall. They said HK redesigned the component to handle that round.

[Kost]

I loved the conversion back in October, and still love it today! Outstanding work by Chris - you rock bud!

Psssttt 12+1= 13 - not 11

I think very many of the .40 loads we buy that are "premium" are at or very close to the 40k psi rating, even some of the "range" loads are there too.

If I had the time I'd go look up some individual ammo specs, but I hate .40 either way so I don't really care :-)

Bullet weight also plays into it as well from what I understand.

[danjackl]

That is the best 10mm I've seen. I wish I could get one. I would even give up my bren ten for one.

[Jimster58]

Has anyone tried modifying a USP 45 magazine, so that the feed lips retain the 10mm rounds and the magazine locks securely in place? I tried a little gunshop "experiment" at one point long ago with the blessings of the store owner, and with the proper skill applied to make the mods, I saw no reason why a factory 45 USP magazine wouldn't work really, really nicely...I swapped an Expert 45 magazine into an Expert in 40S&W.
