Some guns are designed for speed, and that speed comes at a cost. Whether it’s a lightweight trigger, high cyclic rate, or just a design that encourages rapid follow-up shots, some firearms leave you wondering where your last mag went.
If you shoot any of these, you’ll need to keep your gear stocked and your reloading rhythm sharp. These are the rifles and pistols that eat through magazines quicker than most shooters anticipate, especially during drills or range sessions.
Glock 18
The Glock 18 is one of the few pistols capable of true full-auto fire, and it burns through 33-round magazines in seconds. Built for law enforcement and military use, it’s an impressive platform but one that requires discipline to manage.
At over 1,200 rounds per minute, you won’t get much trigger time per mag without serious restraint. While effective in close-quarters scenarios, most shooters find themselves reloading constantly. If you ever run one, expect to carry extra mags — a lot of them — or watch your range session end quickly.
FN P90
The FN P90’s compact design and unique top-fed 50-round magazine make it a favorite for close-quarters work, but its 5.7×28mm chambering and extremely controllable recoil mean you’ll burn through ammo faster than expected.
Because follow-up shots are effortless, shooters tend to hold the trigger a little longer than they should. Even with the extended mag capacity, it’s easy to go through several magazines in no time. If you’re planning on running drills with the P90, make sure you’ve got a pile of loaded mags ready to go.
HK MP5K
The HK MP5K is a compact powerhouse in the submachine gun world, capable of high rates of fire in a lightweight package. Chambered in 9mm, it’s controllable and fast, but that also means you’ll chew through 30-round magazines almost instantly.
Its short barrel and compact frame make it ideal for close-quarters shooting, but the trade-off is frequent reloads. With practice, mag swaps become second nature, but you’ll still need plenty on hand if you plan on keeping the MP5K running during extended training or tactical scenarios.
CZ Scorpion EVO 3
The CZ Scorpion EVO 3 is known for its smooth handling and minimal recoil, which makes rapid-fire shooting tempting. While its 9mm chambering is relatively affordable, shooters often underestimate how fast its 30-round magazines can disappear during practice sessions.
Its ergonomics encourage quick target transitions and double-taps, so you end up burning through ammo without realizing it. It’s a fantastic PCC platform, but if you want to train effectively with one, investing in extra magazines and bulk ammo is almost a requirement.
SIG MPX
The SIG MPX is a pistol-caliber carbine built for speed, and it shows. Its short-reset trigger, minimal recoil, and superb ergonomics make rapid follow-up shots second nature. That’s great for competitions but brutal on magazine longevity.
The 30-round mags vanish quickly when you’re running drills, especially if you’re shooting in fast-paced environments where transitions and controlled pairs are common. Most owners end up buying several extra mags just to keep up with the MPX’s capabilities — and if you don’t, you’ll spend more time reloading than shooting.
KRISS Vector
The KRISS Vector’s unique recoil mitigation system makes it one of the flattest-shooting subguns available, but it also means shooters are prone to firing faster than they intend to. Chambered in .45 ACP, its 25-round mags vanish before you know it.
Because it’s so controllable, you naturally push it harder, which accelerates how quickly you burn through ammo. While its performance is excellent, keeping enough loaded magazines on hand is critical if you plan on spending any time training with the Vector. Otherwise, you’ll constantly be reaching for fresh mags.
IWI X95
The IWI X95 is a compact bullpup chambered in 5.56 NATO, built for fast handling and close-quarters maneuverability. It shines in dynamic shooting scenarios, but with its crisp trigger and quick target reacquisition, you’ll blow through 30-round mags faster than expected.
Even experienced shooters tend to run the X95 hard because of how well it handles under rapid fire. It’s an excellent rifle for fast-paced work, but you’ll need to factor in extra magazines — and extra ammo — if you want to keep it running during extended drills.
HK UMP45
The HK UMP45 delivers heavy-hitting performance in a compact SMG platform, but that power comes at the cost of capacity. Running .45 ACP through a high-rate-of-fire system chews through 25-round magazines incredibly quickly.
Its lighter frame and manageable recoil make rapid shooting natural, especially in close-quarters environments. While the UMP45 is reliable and effective, you’ll need to carry plenty of backup mags to avoid constant downtime. In high-stress training or live scenarios, magazine management becomes a key part of running this platform efficiently.
Ruger LC Carbine
Chambered in 5.7×28mm, the Ruger LC Carbine offers low recoil, fast handling, and quick follow-up shots — a combination that encourages shooters to burn through magazines rapidly. Its lightweight frame and smooth trigger make mag dumps tempting, especially during drills.
Even with 20- or 25-round mags, you’ll find yourself reloading constantly if you aren’t disciplined. While it’s an accurate and fun platform, anyone running an LC Carbine regularly learns quickly that carrying extra mags isn’t optional — it’s mandatory if you want to keep shooting without interruption.
B&T APC9 Pro
The B&T APC9 Pro is a high-end PCC designed for performance under speed. It has exceptional recoil control and a smooth trigger, meaning you can run tight shot strings quickly and effectively. But that performance also translates to rapid magazine depletion.
Even with 30-round mags, drills often require constant reloads. For competitive shooters or those training in defensive scenarios, the APC9 Pro delivers reliability and precision — but you’ll want at least twice as many mags as you think you’ll need to keep up with it.
