Description
The ProMag drum for the Taurus TX22 does one thing and does it well: it keeps your .22 pistol running long after everybody else at the bench is reloading. With 52 rounds on board, you get better than three times the capacity of a standard TX22 factory mag, which turns a single fill-up into a serious stretch of trigger time. It's purpose-built for the TX22 platform, so lockup is snug and feeding stays consistent as the follower works its way up the stack.
What Sets the Taurus TX22 Drum Apart
The body is molded from a DuPont Zytel-based polymer, the same tough material ProMag uses across their drum lineup, and it shrugs off the knocks and drops that come with real range days. Inside you'll find an injection-molded follower and a heat-treated stainless steel spring that keeps steady tension from the first round to the last. Even loaded full, the polymer construction keeps the whole thing light enough that it doesn't throw off the balance of your pistol. Like the rest of the ProMag catalog, this one is made in the USA.
Getting the Most Out of Your TX22 Drum
Rimfire is finicky by nature, and drums ask a little more of the ammo you feed them. Plated rounds like a 36 or 40 grain copper-washed load tend to run best, since the plating cuts down on the soft lead fouling that can gum up the tight internal channels of any high-capacity mag. Plain lead bulk ammo works too, but a quick wipe-down of the internals now and then keeps everything feeding clean. Stick with standard or high-velocity .22 LR and this drum shines at what it's meant for.
Who This Drum Is Built For
Think high-volume range sessions, steel drills, teaching a new shooter, or a lazy afternoon of backyard plinking where the whole point is to keep shooting. Heads up on fitment: this drum seats in standard full-size TX22 and TX22 Competition frames, but it won't lock into the shortened Compact grip. If you've got the full-size TX22, this is about as much fun as you can pack into one magazine.

Frequently Asked Questions
Will this drum fit my TX22 Compact?
No, the Compact uses a shortened grip frame and this drum won't seat properly in it. It's designed for the standard full-size TX22 as well as TX22 Competition models that use the full-size grip frame. If you're running a Compact, you'll want a magazine built for that shorter frame instead.
What ammo works best in the Taurus TX22 drum?
Copper-plated rounds in the 36 to 40 grain range tend to run cleanest and most reliably. The plating cuts down on the soft lead buildup that can slow feeding inside a high-capacity drum. Bulk lead ammo works fine for plinking too, just plan on wiping down the internals a little more often to keep it smooth.
How many rounds does it actually hold?
This drum holds 52 rounds of .22 LR, which is more than three times what a standard TX22 factory magazine carries. That's a lot of shooting between reloads, which is exactly the point for range days and drills. Some folks find topping off the last few rounds takes a firm push, which is normal for a fully loaded drum spring.
Is this a good choice for self-defense?
It's built for range use, training, and plinking rather than defensive carry. For anything you'd stake your safety on, factory Taurus magazines paired with quality ammo are the safer bet since rimfire is inherently less predictable. Where this drum earns its keep is high-volume fun at the range.
