Why Your 2011 Needs Competition-Specific Upgrades for USPSA
The 2011 platform dominates USPSA Limited division for good reason — double-stack capacity, a proven single-action trigger, and a frame geometry that rewards aggressive shooting. But a stock Staccato, Bul Armory, or STI out of the box still leaves significant performance on the table. The difference between a B-class and an A-class Limited shooter often comes down to tenths of a second on reloads — and that's exactly where targeted upgrades pay for themselves in match results.
For US shooters running USPSA Limited, the upgrade priority list is clear: magwell for faster reloads, weighted base pads for magazine drop and recoil management, upgraded controls for consistent manipulation, and (if you're eyeing a Carry Optics crossover) a solid red dot mounting solution. Each of these upgrades is USPSA-legal, bolt-on, and requires zero gunsmithing.
Boss Components designs these parts in Adelaide with a singular focus on competition shooters. For US customers, that means competitive pricing (even after the exchange rate), just 2.6% US import duty versus the 25% tariff on Chinese-manufactured alternatives, and direct shipping to all 50 states.
2011 Magwells for USPSA Limited: Aluminum vs Brass
The magwell is the single highest-impact upgrade for any USPSA Limited 2011. A properly designed funnel transforms your reload window from a precision exercise into a gross motor skill — exactly what you need under the stress of a 32-round field course. Boss Components offers two distinct options for the STI/Staccato/Bul Armory 2011 platform, and the choice between them comes down to your division strategy and shooting style.
STI 2011 Aluminum Magwell — Lightweight Speed
At 44 grams, the STI 2011 Aluminum Magwell adds a generous reload funnel without shifting your gun's balance point. This is the right choice if you're already at or near the weight limit for your division setup, or if you prefer a lighter, faster-handling gun for transitions. CNC-machined from aircraft-grade aluminum and available in seven colors (Black, Silver, Red, Blue, Green, Purple, Orange), it fits all standard STI/Staccato/Bul Armory 2011 grip modules with the standard screw pattern.

STI 2011 Brass Magwell — Weight Where It Counts
For shooters who want to add functional weight to the grip, the STI 2011 Brass Magwell at 94 grams serves double duty — it's a reload funnel and a recoil management tool. The extra 50 grams at the base of the grip lowers your center of gravity, reducing muzzle flip during rapid strings. In USPSA Limited, where you're shooting Major power factor at 165+, that weight advantage translates directly to faster split times. Available in Gold Plated, Chrome Plated, and Black Plated finishes.

Magazine Base Pads That Pass the Box Test
USPSA Limited restricts magazine length to 141.25mm — every base pad you run needs to keep the loaded magazine within that measurement. Boss Components' 2011 base pads are specifically designed to maximize weight and mag-drop reliability while staying within division-legal dimensions.
2011 Brass Double Stack Base Pads
The 2011 Brass Double Stack Magazine Base Pad at $39.99 AUD adds meaningful weight to the bottom of each magazine. At 62 grams per pad, they ensure positive magazine drops even in cold or wet conditions — a common issue at outdoor USPSA matches. They fit all standard STI/Staccato/Bul Armory double-stack magazines and are available in Gold Plated, Chrome Plated, and Black finishes.
For MBX magazine users, the MBX 2011 Brass Magazine Base Pad at $44.99 AUD provides the same weight-adding benefits with fitment specifically designed for the MBX magazine body — increasingly popular among US USPSA Limited shooters.
Thumb Rests, Safeties & Controls for Faster Manipulation
Consistent hand placement and controls manipulation separates good shooters from great ones. For 2011 platforms in USPSA, three control upgrades make an immediate, measurable difference.
Adjustable Thumb Rest
The 1911/2011 Adjustable Thumb Rest ($49.99 AUD) mounts to the frame's accessory rail and provides a consistent index point for your support hand thumb. In USPSA Limited, where you're driving the gun hard between positions, a consistent thumb position means consistent grip pressure — and consistent grip pressure means predictable recoil management. Eight color options let you match your setup.
One-Piece CNC Ambidextrous Safety
The 1911/2011 Ambidextrous Safeties with Shields ($159.99 AUD) are machined from a single piece of stainless steel — no pin joint to develop play over thousands of draws. The integrated shields prevent accidental engagement during aggressive shooting, a real concern in USPSA classifiers where a safety engagement during a string can cost you the stage. Available in Black and Silver.
Extended Magazine Release
The 1911/2011 Extended Magazine Release puts the button right where your thumb naturally falls during a reload. Combined with a magwell and weighted base pads, this completes the reload speed trifecta that shaves measurable time off every mandatory reload in a USPSA match.
Red Dot Mounts: Ready for Carry Optics Crossover
Many USPSA Limited shooters are exploring Carry Optics as a second division — and with the 2011 platform, a single gun can serve both divisions with the right mounting solution. The 1911/2011 Red Dot Scope Multi Mount ($139.99 AUD) fits Holosun, Trijicon RMR, Leupold DeltaPoint Pro, and most standard red dot footprints. It mounts to the dust cover rail — meaning zero slide modification required.
Pro Tip: If you're running Limited but considering a Carry Optics crossover, buy the Multi Mount now and practice with the dot at your local club matches. When you're ready to compete in CO, your mount is already dialed in. The Multi Mount is compatible with both A-Version (standard rail) and B-Version (Staccato/optic-ready) frame configurations.
Boss Components vs US Competitors: Price Breakdown
US shooters have options — so here's how Boss Components stacks up against the primary US-based competition on 2011 upgrades. All prices shown in AUD (Boss Components) and approximate USD equivalents for comparison.
| Upgrade | Boss Components (AUD) | US Competitors (USD) | Boss Advantage |
|---|---|---|---|
| 2011 Aluminum Magwell (Limited) | $109.99 | ~$85–$99 USD | Comparable price, 7 color options |
| 2011 Brass Magwell (Limited) | $159.99 | ~$99–$142 USD | 94g vs typical 70–80g competitors |
| 2011 Brass Base Pad (per pad) | $39.99 | ~$25–$35 USD | 62g solid brass, premium plating |
| Adjustable Thumb Rest | $49.99 | ~$40–$65 USD | Fully adjustable, 8 colors |
| Universal Red Dot Mount | $139.99 | ~$90–$130 USD | Multi-optic compatibility, 7 colors |
A key advantage for US buyers: Boss Components products ship from Australia and enter the US at just 2.6% import duty — compared to the 25% tariff that applies to Chinese-manufactured shooting accessories. That tariff difference alone can eliminate any perceived price gap.

Frequently Asked Questions
Are Boss Components 2011 magwells USPSA Limited legal?
Do Boss Components ship to the United States?
Yes — Boss Components ships directly to all 50 US states. Shooting accessories enter the US at just 2.6% import duty, making total landed cost very competitive with domestic US suppliers. Most orders arrive within 7–14 business days.
Will the 2011 brass base pads fit my Staccato/Bul Armory magazines?
The 2011 Brass Double Stack Base Pads fit all standard STI/Staccato/Bul Armory double-stack magazines in 9mm and .38 Super. For MBX magazines, use the dedicated MBX 2011 Brass Base Pad.
Should I choose aluminum or brass for my 2011 magwell?
Choose aluminum (44g, $109.99 AUD) if you want to minimize added weight and prioritize fast handling between positions. Choose brass (94g, $159.99 AUD) if you want the magwell to double as a recoil management tool — the extra weight at the grip base reduces muzzle flip, particularly beneficial when shooting .40 S&W at Major power factor in USPSA Limited.
What's the best first upgrade for a USPSA Limited 2011?
A magwell paired with weighted base pads delivers the biggest single improvement for USPSA Limited shooters. Faster, more consistent reloads directly reduce stage times on every course of fire that requires a reload — which is nearly every stage at a Level 1 or Level 2 match.
