45 GAP Bullets

45 GAP Bullets for Reloading

The 45 GAP is Glock’s first attempt to introduce a new cartridge to the commercial market. You don’t need to guess which cartridge the 45 GAP was meant to improve upon, and indeed the 45 GAP matches the 45 ACP’s power while reducing the chance of a case neck blowout.

The original max bullet weight for the 45 GAP was 200 grains, which is loaded to a higher pressure than 45 ACP to give it equivalent performance. The 45 GAP’s max pressure is 23,000 psi, about nine percent more than the 45 ACP, to make this possible. Since the 45 GAP is a smaller round, its greater pressure is achieved solely via more powerful powders. The 45 GAP has since been determined capable of firing 230 grain bullets, and load data for 150, 160, and 185 bullets are available as well. The 45 GAP’s bullet is .451 in diameter, so finding the correct bullets for reloading is as simple as finding 45 ACP component bullets.

The 45 GAP is a little shorter than its predecessor, with a .755 inch long case instead of .898 inches. Glock intended this to permit the design of smaller handguns. You could theoretically trim down 45 ACP brass to make 45 GAP brass, but their lengths alone aren’t the only thing that make the two cases different. You’re better off loading once-fired 45 GAP brass or investing in brand new cases.

    Armscor .45 reloading bullets

    I have been reloading for about 24 years. I found the Armscor product easy to reload. I have fired about 50 rounds so far without any malfunction.

    Review by Shootsalot (Posted on 11/24/2020)

    Service and product better than expected

    I had all the components needed to reload except bullets. I had never purchased anything from Widners but, they were the only firm that had 45 cal 230 gr bullets, also from a company with whom I had no
    experience, in their inventory. In desperation, I placed my order. My order arrived in only a few days and there’s been no discernible difference in my shot groups, at the range, using these bullets. I now have a new source, Widners, and an acceptable mfg.

    Why not

    Have shot these before. They are quality bullets. If you did buy throughout the last year now is the time. In stock great packaging and in my case same day shipping. Use for range time or ringing plates. They load perfectly. Do not wait if you have the other components buy now.

    Review by Marty (Posted on 10/22/2020)

    Clean ammo, well made.

    The ammo was just as advertised. All rounds were clean, well assembled, and cycled very cleaning. No feed issues. And a reasonable price. Can't really ask for more, other than a lower price, but the market and materials drives that.

  6. Berry's .452 Diameter Bullets - 230 Grain Hybrid HP – 500 Count (Not Ammo)


    In stock

    Cost Per Bullet 17.6¢ per bullet
    Bullet Weight 230 Grain
    Bullet Caliber 45 ACP, 45 GAP
    Quantity 500
    Bullet Type Jacketed Hollow-Point (JHP)
    Manufacturer Berry's
    Manufacturer SKU 00400
    This is not loaded ammunition. You cannot fire these bullets right after you open their packaging, as they lack cases, powder and propellant. Do not order these component bullets if you do not handload your own ammunition.

    Do order these component bullets if you do handload your own ammunition, though! These 0.452” diameter, 0.610" overall length, 230 grain jacketed hollow points are perfect if you want to make your own 45 ACP self-defense ammo. They’re also perfect if you’re a fan of the 45 GAP and are tired of looking for high-quality ammo for personal protection.

    This is Berry’s Hybrid Hollow Point. It starts out as a swaged lead core, which is electroplated with copper to create zero exposed lead and excellent jacket concentricity. The electroplating process also yields a bonded jacket, so you can count on reliably deep penetration during a self-defense scenario. Every Berry’s bullet is restruck to ensure that it adheres to tight specifications.

    Berry’s advises that these bullets have an effective velocity of 825 to 975 fps. They also advise loading a 1.210” long 45 ACP cartridge. Use a round nose seating stem to avoid damaging the Hybrid Hollow Point’s performance, and do not overcrimp the brass after seating (you can use a roll or taper crimp). Load data are available in any manual or on any propellant manufacturer’s website.

  7. Hornady .451 Diameter Bullets - 185 Grain HAP Bulk - 1900 Count


    In stock

    Cost Per Bullet 20¢ per bullet
    Bullet Weight 185 Grain
    Bullet Caliber 45 ACP, 45 GAP
    Quantity 1900
    Bullet Type Hornady Action Pistol (HAP)
    Manufacturer Hornady
    Manufacturer SKU 45105B

    The 185-grain bullet has no exposed lead, which helps with smooth feeding, ensuring a jam doesn’t cost you a match. The swaged core enhances balance and external performance, while the hollow point delivers terminal ballistics that meet your high standards. With these .451-diameter bullets, you’ll be all set for a full day at the range.

    If you shoot the .45 Automatic Colt Pistol (ACP) round, you understand the need for an affordable yet effective cartridge. Make sure you are reloading your spent cases with high-quality bullets by ordering this 1,900-count box. You’ll get powerful and accurate ammunition that uses Hornady’s HAP design, which is intended for competition shooting.

    Hornady is known for innovation and performance. This company was founded in 1949 with the goal of creating superior ammunition for varmint, big game, and target shooting. Through advanced research and design, they have become one of the most popular brand for many different purposes.

    good projectile

    I love loading and shooting these. easy to load and nice shooting. I do prefer a 200gr but these are fine. As mentioned, they may not be bullseye quality but i shoot lead SWC when i want to be tight. I will say these perform better at higher velocities. When i load down in the 700's they do get loose and seem to like 900 or even a little faster, especially out of tight barrels. So if you aren't getting the accuracy you want maybe drop a few more grains in and see if it helps

    Review by jason (Posted on 6/5/2023)


    HAPs are very accurate and easy to load. Hornady's manual has many loads for the 185, 200, and 230 grains HAP.

    Review by Gunny (Posted on 2/3/2023)

    Very disappointed

    I bought these bullets a while ago to shoot bullseye at 50 yards. I have loaded these bullets with various different powders and loads and I have come to the conclusion that they just don't shoot accurately. Sorry, but I would not buy them again. I have had other issues with the Hornaday brand and I am staying away.

    Review by Till (Posted on 12/14/2022)

    Very good performing bulk target bullets

    I have purchased a couple cases each of these HAP bullets in 9mm, 45 and 40 caliber. They perform well accuracy wise, I’m getting ¾-1” groups at 25yds out of a Sig P220 and a Wiley Clapp 1911 Government, both with Barsto barrels. I would caution that the jackets are thin or soft as I reloaded some Federal primed brass that had bullet sealant and it caused the cone to deform on the 40 caliber bullets.
