I have not shot one of these pistols, nor have I handled one.
I checked out Camstar's site and downloaded the owner's manual here:
https://camstardefence.com/images/star-m30-manual.pdf
What is described is a version of the 1911 that's shorter than the 5 inch barrel Government Model and a bit longer than the Commander model's 4.25 inch barrel -- it has a 4.6 inch barrel. The owner's manual has a very good description of how the gun works and explains what the parts are called and what they do. Diagrams illustrate operation and a parts diagram is included.
This makes it very easy to assess the gun.
It is a straightforward Colt 1911 design. Thus, from the description, it would be safe to carry with a round in the chamber. Whether it is drop-safe or not might be an issue: Colt did not include a firing pin block in their 1911 until the Series 80, and this pistol doesn't have that.
Since Colt offered 1911s in both 45 and 9mm (and 38 Super, too!) it would be fairly easy to adapt the 7.62x25 Tokarev (30 caliber) round, as it is of the same head diameter as the 9mm and very close to the 38 Super diameter. But, 7.62x25 Tokarev is about 0.1 inch longer than both 45 Auto and 38 Super, so Canstar would have needed to come up with 0.1 in the magazine well to accommodate the longer cartridge. Where they got this added length from, I don't know, but I suspect that they may have "stretched" the frame's design to obtain it.
Check the gun in your hand. Some folks with small hands object to the large grip of the 1911, and if this version is stretched, even by a small amount, it may make a difference for you -- or not.
I can't say anything about the quality of the fit and finish, nor comment on the heat treatment and quality of the metal. This will affect how the gun operates and also its reliability in shooting and longevity.
Note that if you want extra magazines, you would probably need to obtain them from the manufacturer, because normal 9mm magazines would be too short for 7.62x25.
I'm not big on that "beavertail" on the grip safety. Most people seem to like them because they prevent the web of the thumb from being pinched by the hammer when shooting. I don't have that problem with my 1911 (stock Colt, no beavertail), but if I did, I'd prefer to have a Commander style hammer that is smaller in the spur area. Having things sticking out can get caught in clothing or whatnot, were one to access the pistol quickly. But this is a personal decision for each owner.
If this gun was made properly, made of proper metals, and was finished nicely, it would be a gun I would certainly consider for myself, for carry or just to shoot.
