$169 10mm Handgun – Hi-Point Conversion

The gun store guys converted a Hi-Point (likely a .40) to shoot 10mm:

Seems to work damn good. ┬áCan’t really beat it for the price.

I’m sure this modification will catch on in the hood, because 10mm kills mo’ bettah!

They never mentioned if they were doing the conversions in their shop or not, but if you’re interested i’d suggest giving them a call.

Cool. Where’s my 9×25 Dillon conversion barrel? :)


Feargal April 24, 2012 at 01:10 am

They seem to miss the target quite a bit ….


Jackyl357 April 24, 2012 at 02:21 am

I am no good on steel either. So I really cant knock them.


Jeep April 24, 2012 at 02:23 am

I guess they are pretty good gunsmith, but damn! they have to stop posting videos where they are shown shooting. Or edit/cut them a bit. They talk like they are gun experts and “we’ve already seen all what can be done with firearms” and stuff and can’t shoot 10 rounds in the target? Come on.


TheRealDave April 24, 2012 at 02:21 pm

Maybe they are comfortable being “pretty good gunsmiths” and not too worried about your opinions on their marksmanship.


Matthew September 10, 2012 at 02:00 am

Game programmers are often lousy at games.
Where is the clause that a gunsmith has to be an awesome shootist.
How about a blacksmith. How many swordsmiths were world renowned warriors?

Those who make things are not the best at using them. After all. They spend their time taking the weapon apart and playing with the internals than playing on the range.

was that bullet just loaded in short? casing was long, bullet head looked very short


Sivl32 April 24, 2012 at 03:00 am

nvm, commented before i finished watching it.

Given that Hi-Point pistols explode more frequently than Glocks, I’m not sure I would trust the metallurgy to stand up to 10mm pressures. At the top end, 10mm pushes around 5000psi more than 40S&W. Seems like a cheap, cool toy. Until you go to the ER to have your face sewn back on.


Crystal Newman April 24, 2012 at 11:03 am

Yep… exactly my thoughts. I like my hands! wanna keep ’em!


Fuzzy April 24, 2012 at 03:06 pm

If a Hi-Point can shoot a carriage bolt out of the barrel without exploding, I don’t think a 10mm will be a problem. Look on YouTube for the Hi-Point torture test. I can’t think of another pistol that would survive what they put it through.


Alan July 27, 2012 at 04:04 pm

Maybe you should check out their other videos. They already did torture tests on a Hi-Point and the only way they could get it to explode would have made ANY firearm explode.


Michael Harris April 17, 2013 at 11:59 am

Hi Points are waaaay overbuilt. These same guys tried to destroy one by loading some ridiculously hot loads through one. Some so hot they triggered it by wire remotely. The gun ate everything they threw at it. They only succeeded when they put a bolt in the end of the pistol and fired it. Even then the barrel just bulged if I recall correctly.


Dave May 13, 2016 at 10:46 am

40 S&W is rated at 35,000 PSI
10mm is rated at 37,500 PSI
difference is 2,500 PSI
40 S&W 180gr. bullet, 8gr. longshot powder 1159fps, 32,300 PSI
10mm 180gr. bullet, 9.5gr. longshot powder 1287fps, 34,600 PSI the longer case lowers the pressure allowing more powder to be loaded, go with 9 grains instead of 9.5 and pressure is practically the same, not saying its safe but most factory loads do not push the limits except!! for those producing extreme hunting loads
Underwood Ammo, Buffalo Bore, etc.
still not saying its safe but is it more dangerous then mountain climbing? or driving fast? or eating out?


crazed April 24, 2012 at 09:19 am

just because it fits is not a good enough reason to try it. Didnt they make a video of people buying the wrong ammunition?


spencer wade April 24, 2012 at 09:57 am

I usually have 10 inches of pentration and good expansion aswell. IF YA KNOW WHAT I MEAN.


Weer'd Beard April 24, 2012 at 11:06 am

The ammo they shot was worth more than the gun.


DonovanM April 24, 2012 at 11:37 am

A Milspec Monkey fan… Why am I not surprised.

And 10″ of penetration doesn’t meet the FBI minimum standard, LOL.


TheRealDave April 24, 2012 at 02:27 pm

I was also surprised at the getlatin results.


PhilaBOR April 25, 2012 at 11:22 am

Does it meet the Secret Service standard?


Jwhite April 24, 2012 at 06:53 pm

‘What do you think Barry?”

Well.. I’ll tell ya what I think.. hiPoints are shit. Always shit. And forever shit. Ghetto/Saturdaynight specials. *eye roll*


dave w April 24, 2012 at 07:49 pm

I do remember seeing them trying to destroy that hipoint, it took a LOT of abuse. It went from ‘watch us blow up this cheap gun’ to ‘what can we try next other than welding the barrel closed’


Ron H May 5, 2012 at 06:59 pm

I guess there will always be gun snobs. All I know is I can generally out shoot most others at the range with my Hi Point 40. I also have a Smith & Wesson Sigma 40 and I like the Hi Point better.


Crunkleross May 7, 2012 at 07:17 am

It’s not so much their marksmanship as their desire to shoot faster than their skill will allow them to hit with much regularity.


ken September 14, 2012 at 09:40 pm

i bet if that bullet didn’t catch that table it would of went into the gel further


tom November 28, 2012 at 10:30 am

how or were can I buy the conversation for the hi point carbine to make it a 10mm or buy one already converted I need one that is California legal.


kscott January 4, 2013 at 06:15 am

has anyone that negatively commented on the hi-point actually owned and shot one? if not stfu!


Dave September 30, 2016 at 10:51 am

most likely not, those who own and shoot them understand them, its like anything else you use often you learn to use it well, pickup something new and your first impulse is generally to dislike it because its different, different makes dislike far to often, learn to understand something or somebody and dislike either fades or occasionally gets stronger, those of us who learned to like our hi-points usually shoot them more then our (insert brand name here) its understanding these facts of life that can be hard.


Alan January 4, 2013 at 10:36 am

I have never seen anyone with a legitimate failure of a hi-point. They couldn’t possibly sell a gun that was a danger to the shooter and stay in business for 20 years.


jeff October 26, 2013 at 08:09 pm

how was the conversion done?


Bob March 13, 2014 at 03:06 pm

I own a 40 HP and it is nothing but good. I also have Sig Sauer and S&W 40 and they don’t do any more than my HP, except cost 4 or 5 times more. I wish I knew enough to convert my 40 to 10mm, sweet.


Jimk November 24, 2014 at 05:52 am

Come on now, A freakin’ Hipoint??!! it looked like he was holding a gun they confiscated from a “Cops” episode!! Why would you they go through all this BS to make an operational 10MM semi-auto that looks that fugly!! Where is the marketability. They should have definitely started with a frame that takes a double stack magazine. If I was the owner of this shop i would be pissed that these guys wasted time on something that would never sell.


Mr. Reliford June 18, 2015 at 11:55 am

Where can I purchase a 10 mm hand gun.


Erick Floyd October 15, 2015 at 11:26 am

There is no need to use racial slurs guys “mo betta”. Cowards with guns are NOT needed, if you got something to say, act like a man and do it to people you face.


Joshua May 25, 2016 at 01:23 am

lol, u must be black. Can only see through the “black” eyes that democrats gave you, where you see everything in a victim mentality and all the whites are out to get you, lol


Seth June 3, 2016 at 08:25 pm

To answer Jimk, what they did must have been a new and untested idea they came up with “thus the video to show and share their success at it”. If you had gunsmith skills of that caliber, would you try something that has a chance to destroy a perfectly good firearm on a expensive weapon or a cheaper one? High point is ugly but durable in a overkill kind of way while being very low cost. AIso I seriously doubt they would ever sell a weapon they converted in such a way due to the chance of getting sued if anything went wrong once in the new owners hands.It was a really neat display of their gunsmith talent, as well as something out of the ordinary that I’m sure we ALL wish we could do. Let’s not criticize the few of us who CAN do such a thing or they may stop and that would suck.


Dave June 16, 2016 at 10:55 am

Its not exactly an untested idea anymore, a number of people have done it, (very successfully I should add) and the guns function just fine, for those of you who think its to much pressure please consider this, if you take 35000 PSI (SAAMI spec on the 40 S&W) X 1.072 you get 37520 PSI (SAAMI spec for the 10MM is 37500 PSI) so you are over pressuring your 40 by 7 percent, most gun company’s pressure test their handguns to way over 7 percent, some go to 60 percent over pressure, very few ammunition company’s and very few re-loaders load up to the maximum limit so pressure really should not be a problem, if you are concerned about pressure see my earlier post about reducing the charge in the 10mm by .5 grain giving it 40 S&W pressures with higher performance, the real advantage with the 10mm is in the longer case which runs lower pressures then a short case, allowing more powder thus more speed for the same pressure, use your calculator and make it safe, safe enjoyment is the bottom line in experimenting is it not?
and yes I do own hi-points, yes I am a re-loader, and yes my conversion gun has over 150 rounds through it and counting, and yes I started out with 28000 PSI loads, nervous? no, careful? yes.


Melon September 8, 2016 at 07:21 am

Dave, you seem to know the pressures well, what’s your option on wild cating a hi point to shoot 400 core bon. Pressures Max at 2900 much easier in a hi point for built for 35000 +p and less pressure and wear than a 10mm conversion


Dave September 27, 2016 at 11:08 am

Melon, that is another conversion I had considered then put on the back burner for later, I think it would work just fine but rechambering the 40 s&w to 400 cor bon is much more difficult because of the bottle neck design, the 10mm is straight wall like the 40 so all it requires is a .425 reamer and a little patience, pressures with the 400 cor bon should be no problem at all since as you have already noted the highest listing for the 400 is 29000 psi and the 40 s&w is rated at 35000 psi.


Doug Cook August 13, 2016 at 09:14 am

Can you get the 22 lr wmr ammo?


Melon September 29, 2016 at 03:56 pm

Dave if you ever descide to try the conversion or know someone who can do the barrel let me know. Id be interested


Mr. Mike October 24, 2016 at 02:45 pm

I did the conversion back in June, 2016. I’ve fired some pretty warm loads through the thing – and even had one jam the bullet into the brass during the feed cycle, resulting in a smeared, backed-out primer that was punctured. The old Hi Point brick is just fine ! I even went over to the ghost ring sight – and LOVE how this thing works. I also used the recoil spring from the JHP 45, which has kept the bolt in battery a bit longer as well as reducing the beating on the frame. It was a good decision. I have a 69 dollar 10mm pistol…. and it is a FINE old weapon….

Smile !
