Theoretically, could a standard 4053 barrel be recut to accommodate 10mm?

If not, why?

Could it be made to function reliably in a 4053?

(Also, is there a 4056 model?)

Search is your friend ;-)

bad_man_one has a few threads cooking on this topic.

The short answer is yes.

Single Stack 4013/4014/4053/4054 only can be modified to 10 m.m.

There was a 4053TWS and a 4056TSW, but they were a double stack and will not work as a 10 m.m.

Stu,

Not to offend you, but people who say "search is your friend" tend NOT to have tried to search for a very specific topic.

It might put you in the vicinity -- but it tends to be a "vicinity" where you'd already covered ground.

(To switch analogies, I was already "in town," but was asking for specific directions to a street intersection that wasn't readily apparent on the map...and was told to use a map...)

In other words, with "search," it's next to impossible to find something this specific with any degree of efficiency -- and I'm a big fan of efficiency.

In short, I'm asking the question BECAUSE I'm aware of BM!'s work.

It was unclear whether by "conversion" barrel, it meant he was cutting new barrels that "convert" one caliber to another -- or whether he was "recutting" existing barrels and thus "converting" the calibers.

I'm not a machinist -- and didn't see the answer jumping out at me from having scanned the threads.

It's simply easier to ask a straight-forward, specific question -- on a distinct, separate thread.

If he's "recutting" existing OEM barrels -- and they're working -- then it'd behoove us to pick up spare barrels where appropriate -- if we're interested in having him do this work -- either now or later. Thus, if he's doing this on an on-going basis, we'd have the spare barrel for him to "recut" -- in case Smith stocks ever ran out.

BUT...

If he's machining barrels from blanks -- and he has a limited supply, then it's a different story altogether...In other words, buy now -- because there might not be any later...

BM1,

Don't mean to be denser than lead, but...

On the 4053s, for instance, are these 4000-series, OEM barrels from Smith that you've re-cut and modified from .40 to accommodate 10mm?

Or, are they "blanks" that you've completely machined from scratch barrel stock into 10mm new barrels that fit into the models you've mentioned?

Either is completely plausible -- and I'm still not clear which you're doing.

(If it's in your original posts, I missed it...)

Also, how much reliability testing have you done? Do the re-worked barrels function up to expectation?

While it would be no big deal to rechamber a 4XXX barrel to 10mm, I have difficulty seeing a 10 mm cartridge fitting in a 4XXX magazine. The 10xx mag sure isn't gonna fit the 40XX frame. In short, while it is fairly simple to make a 10XX shoot .40, making a 40XX shoot 10mm is probably not doable except as a single shot.

epj,

The old style 4013/4053 are on a 4516-sized frame. The mags have a filler in the back to work properly with the .40S&W. In short, the model in question is a .45/10mm sized gun in .40S&W. bad_man_one has conducted live fire testing of the converted guns, with notable success.

@Outrider,
No sweat. And I have searched before and am aware that it can be a pain.

I wasn't aware that these guns were on the large frame. That being the case, a rechambering and removing the filler in the mag ought to do it. I suspect a recoil spring change would be in order as well.

The most recent 4013/4053 were on what I would describe as a 6906-sized frame, IIRC. So the newest examples would definately be out for this conversion.

Yes, a recoil spring change is part of the conversion.

So....

Are BM1's barrels modified, recut, recchambered OEM Smith barrels?

Or are they completely new barrels -- CNCed from scratch totally from stock blanks?

A .40/ 10mm barrel in a 4516 slide would SEEM to leave a gap between the barrel and inside slide housing.

In that case, a completely new-CNCed barrel from stock blank would seem necessary to fit and look good.

Ok,
Here it is again,

Only the Single Stack 4013/4014/4053/4054 can be modified to 10 m.m.
The magazines were designed to accept the 10 m.m. but it was never made,
So,
S&W put a spacer in the back of the magazines and chambered it to .40 S&W.

I get a new barrel from S&W, re-chamber it on CNC machines, modify the magazines to accept 10 m.m.
and put in a much stronger recoil spring.
I am 100% pleased with the results that have been achieved.

There was a 4053TWS and a 4056TSW, but they were a double stack and will not work as a 10 m.m.

OK, got it...

Looked three times before -- but the Evelyn Woodhead's Speed-Reading course must have tripped me up...

Now, next question, CAN you CNC barrels from scratch?

It would seem that a .40/ 10mm barrel in a 4516 slide housing would leave a gap surrounding the barrel's perimeter.

I understood about the later model TWS double double stack magazines.

I'd love to see someone figure a way to jerry-rig a way to get the double stacks to accept 10mm -- including manufacturing new after market product.

(But the reasons would likely become apparent if I could see and compare the pistols "in person". I'm guessing the TSW models weren't large frame -- and getting them to take 10mm would be next to impossible. If so, that's a shame...)

I am, please read post #92:

I think it will answer all your questions.
