s & w 10mm model 1076

does anyone know if the older model s & w model is capable of handling the hotter loads ie. 1300fps over a long period, is it a safe gun.

I have a 1006, it will handle heavy loads all day long. Since the 1076 is based on the same design, I don't see why it should be any different.

The 1006 series or the Glock 10mm's are the only guns proven to handle full power 10mm loads. I'd not worry about using them in either of those.

The 1076 is sort of a "Commander" model, with a shortish barrel. If you want to get to 1300fps, and prefer the decocker, get the 5" 1026 (if you can find one).

I have a 1076 and it has handled everything I have ever fired in it and is still in exceptional condition. Built like tanks. I also have a G29 and I can say the difference is build quality between the 1076 and G29 is pretty substantial. I have fired everything from Norma to Buffalo bore through mine with no ill effects.

If it were me, I'd contact ....

Smith and Wesson's Pro Center(custom shop) or the customer service office.
Noted gunsmith & S&W custom shop; may answer that ? too.

The 1076 and the rest of the series was design to fire the hottest loads in the caliber before the FBI ordered the production of the "FBI Lite" 10mm which itself lead to the .40S&W. So..., yes!

Yes. Barrel support on my 1006.

I love chamber pics. You should see the chamber support on a 4566tsw. And these guns feed "anything" best of both worlds

1076 will handle full power. But when reloading I prefer to load for accuracy not just velocity.

I have owned, shot and reloaded for more the one example each of the 1076, 1026 and 1006 since about the time 10MM dies and bullets became available. So long ago in fact, that initially, the only .400" bullets available were the 180 grain soft points designed for the .38-40. I have used the original factory Norma, and much more recently Buffalo Bore, other manufacturers' "real" 10MM ammo in all these guns. No problems. In fact the S&Ws handle all the ammo I ever shot without any of the buffers and extra heavy recoil springs,etc mentioned just about any time the 10MM cartridge fired in the 1911 platform is discussed. BTW I checked some of my old chronograph data, and by "real" 10MM ammo I meant loads like the factory Norma 170 at 1293fps, 200 at 1218fps, Corbon 135 at 1475, Buffalo Bore 180 at 1380 fps,etc., and equivalent reloads. I chronographed these velocities in 5" guns, velocities in the 1076 with 4.25" barrel were a little less,e.g., the 200 grain Norma averaged 1186 fps in the 1076.

I mention these actual velocities just to illustrate some of the warmer factory ammo that worked fine in my 1076s. In short, I did not, and would not, hesitate to use any quality 10MM ammo in a 1076, or other S&W 10MM semi-auto or revolver...ymmv

The S&W 10xx series of guns are all heavily-built and quite rugged and I've never seen nor heard of any problems with them that could be directly attributed to the use of "full power" ammunition. The 10xx series, and the 1076 in particular, did experience a few growing pains including issues with the decocker lever and a redesign of the grips (the originals could break in such a way that they tied up the gun if dropped just right) but those were sorted out long ago.

That being said, if a person wanted to shoot a steady diet of "full power" 10mm ammunition through a S&W 10xx series gun, replacing the recoil and magazine springs with extra power ones wouldn't be a bad idea. The factory recoil spring in the 1076 is 17lbs which I suspect was chosen to ensure reliable functioning with the downloaded "FBI Lite" level loadings. For heavier loadings, a stiffer recoil spring (I prefer a 22lb spring) will not only reduce the force with which the slide impacts the frame, but also prevent premature opening of the slide which can cause large extreme spreads in velocity. I would also recommend increased power magazine springs as the increase in stripping pressure will slow the slide's forward movement and thus prevent the slide from closing with excessive force.

I've made these modifications to my own 1076 because most of my 10mm shooting is with medium-to-full power defensive ammo like Winchester Silvertip, Hornady XTP, Double Tap, and Buffalo Bore or medium-to-full power handloads (my regular practice loading is a 180gr cast bullet over 10gr of Blue Dot, but I've been considering working that upward a bit). Even with this spring setup, I've only experienced a few isolated malfunctions with very lightly loaded ammunition such as Prvi Partizan and light Unique handloads.
