I love this pistol. My personal favorite polymer .45 cal pistol. The quality is evident when you hold it and when you shoot it. Very smooth shooter. HK did a fantastic job engineering this pistol. I don't have the biggest hands but I can comfortably hold and fire this pistol, even with one hand. It has fired all the ammo I've fed it, a healthy mix of FMJ range ammo and various defensive ammo, with no malfunctions and I don't ever expect any. I also think it's a great looking gun. If Batman carried a .45 this would be the one he carried. The standard photoluminescent sights work very well; I opt for them on my HK's over the upgrade to night sights. They stand out during the day, and glow bright at night for limited but more than long enough duration when charged. Hit them with a flashlight quickly and they'll glow long enough should you have to get up at night to check your home/ property. Definitely an elite quality full size 45. I'd give it 10 stars if it was an option. I'd also give 10 stars to Impact Guns. I've bought from them a number of times with no problems ever. The staff is always quick to respond if you contact them for anything. The prices are some of the lowest I've ever found. Low shipping, and no extra fees. Impact Guns is an elite firearms retailer, very professional. Loyal and happy customer for life. Thanks again!!
