Why Base Pads Decide Your Match
Most 2011 shooters obsess over triggers and optics while ignoring the part of the gun that hits the ground between stages. That's a mistake. A magazine base pad does three measurable things to your stage time.
It moves mass below the grip. A 152g brass Open-division base pad drops the magazine's center of gravity roughly 25mm lower than a stock polymer floor plate. Lower mass means less perceived muzzle flip when the slide cycles ā especially on the 6th through 9th rounds where grip fatigue starts to show. Shooters running major-power-factor .38 Super report recoil recovery improvements of 0.08ā0.15 seconds per shot in timed drills once brass is added.
It widens the insertion funnel. A flared aluminum or brass base pad gives your palm a larger target on the reload. On a 5-second classifier where reloads are 1.4s each, shaving 0.2s off a single reload puts you roughly 4% higher on the stage. Stack that across a 10-stage match and you move up percentage brackets.
It protects your $80 tube. 2011 magazine tubes are stainless and expensive. A steel or brass base pad absorbs the impact of a hot-drop onto concrete. A cracked polymer factory pad doesn't.
The right choice depends on your division, your power factor, and whether you're chasing weight or shedding it. For the full breakdown of every 2011 upgrade ranked by impact, see our Complete 1911/2011 Competition Upgrade Guide.

This is the first question to answer before you buy. The material drives everything else.
Brass (Heavy ā 60ā152g)
Brass base pads add serious grip-anchoring weight. In IPSC Standard and USPSA Limited, this matters because the rules permit magazine weight up to the mag well floor. Brass also sits in your hand with a planted feel that polymer can't replicate ā useful if you run lighter race guns or suffer from muzzle climb on fast strings. The tradeoff: brass patinas, plating can wear at the corners, and the added mass slows your magazine drop marginally when the release button is pushed.
Aluminum (Light ā 22g)
Aluminum gives you the wider reload funnel without the added mass. In IPSC Production and Standard Minor-power-factor setups, extra weight in the magazine is actively unhelpful ā it drags the tube on reloads and can slow mag-ejection after the release is punched. Aluminum is also kinder to your holster and belt attachments. The tradeoff: you give up some recoil-damping benefit, and the anodized finish can scuff from repeated concrete drops.
ā” Quick Rule of Thumb
Running Open or Limited at major power factor? Go brass. Running Production or shooting minor PF? Go aluminum. Running Carry Optics? Aluminum ā Carry Optics has weight limits you don't want to flirt with.

ā Division Compliance
- USPSA Limited: Any weight, 140mm OAL max ā brass is optimal
- USPSA Open: Any weight, 171mm OAL max ā 152g brass is the class standard
- USPSA Carry Optics: 22-round mag limit, aluminum preferred to avoid OAL penalty
- USPSA Single Stack: Brass acceptable, power-factor-specific mag capacity rules apply
- IPSC Standard: 140mm OAL box dimensional limit ā 62g brass fits
- IPSC Open: 171.25mm OAL limit ā 152g brass Open pad designed to this spec
- IPSC Production: Prefer aluminum; production restricts aftermarket mods heavily

Fitment Gotchas & Install Tips
Three common mistakes cost shooters their stage time on base-pad install day.
1. Magwell interference. Aftermarket flared magwells (particularly aluminum race-gun magwells) can catch on oversized brass base pads during insertion. Result: the mag seats short and your slide doesn't pick up the top round. Fix: test seat every magazine with the slide locked back before the match. If the magazine doesn't drop free when the release is punched, the pad is too tall for your magwell.
2. Wrong magazine brand. The BUL Armory-specific brass and aluminum base pads only fit Mec-Gar-sourced magazines. If you've swapped to Chip McCormick, Wilson Combat, or Metalform tubes, you need the Multi-Fit pad instead. Measure your magazine's floor-plate cutout before ordering.
3. Retention clip loss. Most base pads do not ship with retention clips. Keep your factory clip and reuse it ā it's the internal C-clip that locks the pad to the mag body. Lose it and you'll be reloading with a floor plate in your hand.
Typical install time is under 5 minutes per magazine using a small screwdriver and a bench block. No permanent modifications to the tube.
Frequently Asked Questions
Which 2011 base pad is legal in USPSA Limited?
The Boss Components 2011 Brass Double Stack IPSC Standard base pad at 62g is sized for 140mm overall magazine length, which is compliant with USPSA Limited and IPSC Standard division. Always measure total magazine length with the base pad installed before your first match.
How much weight does a brass Open base pad add?
The STI 2011 Brass Double Stack Open base pad weighs 152g. Compared to a factory polymer floor plate at roughly 8g, that is 144g of additional grip-anchoring mass ā enough to measurably reduce muzzle flip on major power factor .38 Super and 9mm Open loads.
Will a Boss Components 1911 brass base pad fit my Wilson Combat magazine?
The 1911 Brass Multi-Fit base pad is designed for Metalform, Dawson Precision, and Tripp magazines. Wilson Combat magazines use a different floor-plate cutout and may not fit ā check your magazine brand before ordering, or contact Boss Components with the magazine model number for a compatibility check.
Do I need different base pads for 9mm and .38 Super 2011 magazines?
No. The 2011 Brass Double Stack Open base pad fits both 9mm and .38 Super STI, Staccato, BUL Armory, and SVI magazines. The caliber difference is in the feed-lip geometry at the top of the tube, not the floor-plate cutout at the bottom.
How long does it take to install a 2011 base pad?
Approximately 5 minutes per magazine. Use a small flat screwdriver to depress the retention clip through the factory floor plate's access hole, slide the old plate off, reuse the retention clip with the new base pad, and slide on. No permanent modifications required.
