Star Megastar: Spain's Massive 10mm Autopistol (ad-free)

As noted, the .38 Super also has “high pressure”. In fact, its SAMMI max pressure is 36,500 psi. It has been chambered in 1911-type models for almost 100 years, so by far the most common .45 ACP model seemed to have few issues with going to a “high pressure” cartridge back when Herbert Hoover was President.

The comparison that's important is 10mm vs .45 ACP (not 9mm) because .45 ACP guns were being directly converted to 10mm without consideration for the increased pressure and the guns suffered for it.

Agree, I have three of them and the only issue is getting parts for them. I take them to CCW classes I help with and loan them to people that don't have decent weapons. They all rave about them.

I love the Star BM, for a long time it was the only 9mm I thought was worth owning

Looks just like the new sig

Certainly looks like the Star 10mm pistol was engineered to last and survive the battering that Colt's Delta was getting, so after the Assault Weapons ban died, why didn't Star continue with this pistol? I have several of the Star BM pistols and enjoy them so their quality is fine, just getting parts now is the problem. I assume if I was to find one of these MegaStar 10mm pistols I would have the same problem....no parts.

Very cool, thanks

It looks like if you asked CZ to make a SIG pistol.

Glock's approach was similar. The G20 was a scaled up G17, built for 10mm from the ground up, with the G21 in .45 coming later. Question: but for the 10mm, does the .40 ever gain traction? Or does the 9mm continue to be refined by designers like Lee Jurras to the point where its perceived deficiencies compared to the .45 ACP are eliminated?

Does the megastar in 45 have a fully supported barrel where it would be possible to shoot 45 super with a higher rate recoil spring? The extra weight would help out with the extra recoil.

The 38 super auto is also up there in the pressure spec. Perhaps because it is a significantly larger cartridge that was optimized for 180 and 200 grain bullets at a higher velocity than 9mm with its standard bullets rather than something significantly lighter so there is a much more significant amount of force driving the slide rearward. The whole mass x velocity squared thing.

You should do a history of Interarms. It was a real shame when they closed up. There was a great gun shop just down the street in an old ferry station building that was super cool and it closed when the City of ALexandria realized its aspirations to fully yuppify/touristify the waterfront. They drove the boat club out as well... :(

I’m always a little surprised when people focus on the “horribly high pressures” of the 10 mm. The 9 mm Para is over 120 years old, and its SAAMI max pressure is 35,000 psi, compared to the 37,500 psi of the 10 mm. Why is the 10 mm considered to have such high pressures when it’s barely above the most commonly used pistol cartridge in the world that is 120 years old?

Well, they were inexpensive before this video.
