Description
When it comes to 1911 magazines, Wilson Combat's 47-series has been the benchmark for decades. The 47OXCB is the Officer/compact version of that legendary lineup, sized specifically for the shorter grip frames found on Officer's ACP, Defender, and similar compact pattern 1911s in .45 ACP. It will not fit full-size Government or Commander frames, so make sure your pistol runs a compact-length magazine before ordering.
Construction starts with a tube made from aircraft-grade 17-7 PH stainless steel at .025 inches thick, which Wilson Combat claims is the thickest wall in the industry. The tubes are heat-treated for maximum service life, and the tight dimensional tolerances mean the magazine should drop free cleanly and never bind your rounds inside the tube as long as your pistol and ammo are reasonably in spec. The heavy-duty spring is fabricated from maximum tensile strength wire to handle consistent cycling, resist fatigue over time, and deliver reliable slide stop engagement on the last round.
The follower is a fiber-fill self-lubricating nylon design that keeps rounds feeding smoothly through the mag's travel without tilting or binding. The low-profile steel base pad is removable for easy cleaning and maintenance, and it gives you the option to swap to a different base pad down the road if your setup calls for it. The black finish gives it a clean, subdued look that works just as well on a carry gun as it does at the range.
Wilson Combat backs the tube with a lifetime satisfaction policy. If the tube spreads, cracks, or becomes unusable through normal use, they'll replace it. Springs and followers are considered consumable parts and may need replacing with heavy use, which is standard practice with any quality magazine. It's made in the USA, and it's the kind of magazine a lot of 1911 owners reach for when they want something they can trust for carry, training, or just putting rounds downrange without thinking twice about the mag.

Frequently Asked Questions
Will the Wilson Combat 47OXCB fit my Kimber Ultra or Defender-size 1911?
In most cases, yes. The 47OXCB is sized for compact/Officer-pattern 1911 frames, which includes most Kimber Ultra series and Colt Defender variants. That said, some Kimber models with unfinished barrel feed ramps can cause fitment issues, so it's worth confirming with Wilson Combat or running a test round before committing. Note that the Kimber Micro series and Springfield EMP use proprietary magazines and are not compatible.
What is the difference between the Officer/compact magazine and a full-size 1911 magazine?
The compact/Officer magazine has a shorter tube designed to seat flush with the grip of a shorter 1911 frame. Full-size Government and Commander 1911s use a longer tube that would protrude well below the grip on an Officer-frame pistol. The 47OXCB is specifically sized for compact frames and will not function correctly in a full-size Government 1911.
Can this magazine be stored loaded for extended periods without damaging the spring?
Yes. Wilson Combat specifically designs their magazine springs to remain fully loaded for long periods without taking a set or losing tension. The heavy-duty, high-tensile spring wire is built to resist the kind of fatigue that degrades cheaper magazine springs over time. This makes the 47OXCB a solid choice for a carry or home defense setup that stays loaded.
Is the base pad on the 47OXCB replaceable or upgradeable?
Yes, the low-profile steel base pad is removable, which makes cleaning and maintenance straightforward. It also gives you the flexibility to swap it out for a different Wilson Combat base pad style down the line if your needs change. The steel construction of the included pad is a good choice for hard use since polymer base pads can crack if a loaded magazine is dropped on a hard surface.
Does Wilson Combat offer any warranty on the 47OXCB magazine?
Wilson Combat backs the magazine tube with a lifetime satisfaction policy. If the tube spreads, cracks, or becomes unusable under normal use, they will replace it. Springs and followers are considered consumable items and are not covered under the same policy, though they are available separately and are user-serviceable.
How many of these magazines should I buy for regular range use or carry?
For carry purposes, having at least two magazines is a practical baseline. For range use or training, most people running a compact 1911 regularly prefer to have three to five on hand to keep the session moving without constant reloading. The 47OXCB is a common magazine to buy in multiples specifically because it's built to last and feeds consistently.
