It should make a really nice set up for the 10mm. I was looking at them and they look very well made and thought out but the weight is pretty high for a pistol caliber carbine except for the 10mm which is a pretty hot cartridge. It is only a 5 ounces under my 6 lb 13 oz AR with steel flip ups and a red dot. My 9mm Sub 2000 weighs just under 6 lbs with 18 rounds on board, a red dot, laser, rails, forward grip and a Red Lion front sight. Dont expect a major boost in power with the longer barrel. The pistol cartridges are pretty efficient in short barrels and gain is only 100 to 150 fps in most cases. Not like a 357 magnum that gains 300-400 fps. You can get some additional boost if you hand load specifically for the long barrel.
