HK45 BB Pistol

Metal Barrel & Slide, Replica of the firearm HK45

Out of Stock
Our HK45 replica CO2 pistol doesn't have any recoil, but that's actually a plus. A recoiling CO2 gun gets fewer shots per cartridge so you'll save some money right there. Because it's not a very heavy CO2 pistol, just about everyone in the family should be able to handle this gun. Get out the bullseye paper targets and tin cans and start having some fun! The HK45 firearm was created to re-arm the entire U.S. military with a .45-caliber handgun instead of the 9mm. And the cost of doing that is what led to the cancellation of the program. However, Hechler & Koch knew they had a winner and opted to make it available commercially. This BB pistol is a replica of the firearm.

H&K 45 BB Pistol Features
  • CO2-powered
  • Uses one 12-gram CO2 cartridge
  • Shoots steel BBs
  • 20rd drop-free BB mag
  • Double-action only
  • Fixed front and rear sights
  • Integral Weaver accessory rail under the barrel

Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area as rebounding ammo can hit them too. Never shoot steel BBs at hard objects (including metal targets) or waterb as that increases the chance of ricochet.

Be sure to lube the CO2 cartridge head before installing it. Keep the barrel clean of dust/debris.

Excellent CO2 pistol for an economical price. So impressed, this is my second one. Accuracy is good and air supply last for a while. Full size pistol size, not for small hands. Fully recommend this product.

Bought this and the S&W M&P pistol together to start teaching my wife basic firearm safety and work on weapon manipulation. (I have both of the weapons in the REAL DEAL versions. Lol). They will do just fine for my purpose.

Comfy, good price

This H&K45 BB pistol pretty accurate, and it delivers good power. I really like the all metal 19 round drop free magazines. and the white dot sights are a BIG PLUS. I'm giving it 4 stars because for the price, it should have a windage adjustable rear sight..,,,,Mine shoots off to the right, But it's still in close second place behind my Daisy PowerLine 415, which is about the most accurate BB pistol I've ever owned and retails for just $30, but with a 20 round fixed mag instead of a drop mag.... . I RECOMMEND THIS HK45 BB PISTOL FOR PLINKING OUT TO 18 YARDS, Be sure to purchase a couple of extra magazines to get the full effect from this BB gun.

19 round drop out magazine and 3-dot sights Shipped fast, less than 5 days.

Shoots off to the right, really needs a windage adjustable rear sight...!

Very nice looking weapon! As represented (except the number on the left hand side as shown in the photo is not present). Shot only one mag so far. It shoots to the left 3" at 22 yards but is consistent - so you can adjust your aim accordingly (sights not adjustable). Maybe it will settle down with more rounds fired. Trigger pull is not lumpy or scratchy, and lets off crisply for accurate shot. Good sound - and not too loud.

Handsome and realistic. Plenty of branding and minimal warning label. Mag drop is xrisp and falls nicely. Easy to load compared to some. Good power Great in-hand feel Great price for the gun

Shoots to the left - non adjustable sights. Could be a bit heavier.

Trigger pull - hard or easy?

asked James from USA

Hi,I'm wondering is this pistol come with a orange tip?Thanks.

asked Kevin

no most bb guns do not have a orange tip because there not meant to be played around with like a Nerf gun, these are meant to be used for hunting/target practice not something to be walking around your neighborhood with like a Nerf gun like a lot of people think
