Extremely accurate. Extremely reliable. You will die before it will. A must for any serious collector. A little more muzzle flip than I'd like. Other than that - perfect.

Top of the heap. Nothing else compares...not even close. Love my SIG collection, and the mention of Glock is enough to put a tactical shooter into a full body dry heave. Go HK or die like a pig.

This gun just runs! It's built like a tank, and you can feel it the moment you pick it up. Honestly, it's one of the softest shooting .45 ACP's you'll ever shoot. I have friends who usually shoot strictly 9mm's and they've even said that this gun made them reconsider their stance on the cartridge. I don't have super large hands, and I'm able to easily grip this firearm and make accurate follow-up shots with ease. Yes, it's a little heavy. Yes, the mags can be expensive. Yes, it's expensive. Yes, yes, yes, you I've heard it all. But, once you pick this thing up and shoot it--you won't regret a single cent of your purchase. Eurooptic has thee best pricing available on this particular handgun, so I strongly recommend that you purchase from them! Also, shoutout to Derek at customer service, you're the man!
