The Heckler & Koch USP .45 semi-automatic pistol weighs 789 grams (1.74 pounds) unloaded.
$600-$650, depending on condition.
The USP .45 utilizes .45 caliber bullets, as the name suggests.
I'd recommend the M9 or USP.45 because they both have good accuracy. Akimbo Deagle and Magnums are better for close range.
500 USD
The USP tactical since it is less bulky in size and weight.
2 tuned Heckler&Koch USP
.45 ACP
How much is a old black powder only 45 cal long barrel pistol worth?
$400 new
It depends on preference, but the best in classes are ACR (Assault Rifle), Barrett .50 cal (Sniper), UMP .45 (SMG), AUG HBAR (LMG), G18 (Machine Pistol), USP .45 (Pistol), M1014 (Shotgun), AT4-HS (Launcher). These are the most balanced weapons according to damage, accuracy, etc.
