As you may know the cartridge is not based on the 9mm Luger. It is,in fact, a shortened .223 cartridge. The 22 Micro-Mag is the same cartridge.
The pistol is fairly priced and you should be able to buy one for under 600 bucks out the door if you shop around.
It also comes with a 9mm Luger barrel and recoil spring. You only get one hi-cap magazine with the pistol. A new magazine is only 28 dollars. Not too bad for a new pistol. Another manufacture uses the same magazine for double the cost!
I have one of these pistols and the little cartridge is one of those that far outperforms its size.
The muzzle blast is very impressive with the recoil being like a .38 Special shooting a mid-range wad-cutter load. A follow up shot is not a problem.
The pistols sights are well made and adjusting the POI was easy. The little cartridge preformed very well and will group the bullets with the best of them. I have a 5.7 as well and this little cartridge has an edge on down range performance. A plus is the ammo is cheaper to buy and the factory will reload you once fired brass for 1/2 the cost of a new box! No one else does this.
In Israel, this cartridge is known as the .223IMI. A few photo's of their ammo can be found on the web. The details are not being shared but you can see the bullet is sold bronze/brass.
The factory loads I have tried will blast right through a 1/4" steel plate set to 50 yards. And that being a soft point. The "solids" will be be a better combat load.
The pistol is well made and the slide has been honed onto the frame rails. It is very smooth to cycle. Trigger is crisp and broke at 6 pounds.
The pistol is all steel. No parts other than the grips are plastic.( the grips on the first models are so cheeze-ball that the factory is replacing ,for free, the grips to a new Epoxy impregnated canvas grip set.) You boaters know this material as most capstans and blocks on boats are made of this material.
As for a home defense round I'd have to hold back. The fireball is very impressive and your night vision would be gone after the first shot.
As for a CCW it will be a plus. After seeing first hand what the bullet will do to steel and other material,I'm taking it on a hog hunt the end of this month as a back up firearm.
Will it fail on the market? Who knows? It is fun to shoot,will be very inexpensive to reload ( no dies sold as yet) and still be a centerfire cartridge with really outstanding performance.
The pistol is cheaper than the FN 5.7. and it is a M1911 to boot. Got to love it.
