Understanding 1911 Magazine Compatibility
Unlike some platforms where base pads are universal, 1911 magazines come in distinct tube types that require specific base pads. Choosing the wrong base pad means it simply won't fit—or worse, won't lock properly.
The Two Main 1911 Magazine Families
Most 1911 magazines fall into two compatibility groups based on their tube design:
Metalform / Dawson / Tripp Pattern: This includes Metalform magazines (commonly supplied with many 1911s), Dawson Precision magazines, and Tripp Research magazines. These share a common base pad interface.
Mec-Gar / Bul Armory Pattern: Mec-Gar magazines (popular aftermarket choice) and Bul Armory magazines share a different base pad design that's not compatible with the Metalform pattern.
Critical: Always identify your magazine type before ordering base pads. Check for manufacturer markings on the tube or consult your magazine supplier.

Brass vs Aluminium: Which Material for 1911?
| Feature | Brass Base Pad | Aluminium Base Pad |
|---|---|---|
| Weight | Heavier - improved drops | Lighter - minimal addition |
| Magazine Drops | Faster, more positive | Standard performance |
| Durability | Excellent - brass is resilient | Good - anodising may wear |
| Finishes | Gold, Black, Chrome | Black, Blue, Red |
| Best For | Competition performance | Weight-conscious setups |
| Price | $39.99 AUD | $34.99 AUD |
Our Recommendation: For competition use, brass base pads provide noticeably better magazine drop performance. The weight advantage translates directly to faster, more reliable reloads—especially important in Single Stack where every reload counts.
Division Compliance Guide
IPSC Classic Division
Classic Division allows 1911-pattern pistols with specific restrictions. Aftermarket base pads are permitted, and brass options provide competitive advantage without compliance issues.
Recommendation: Brass base pads for all magazines. Verify overall magazine length meets division requirements.
USPSA Single Stack Division
Single Stack allows 1911 pistols with traditional magazine capacity limits. Aftermarket base pads are legal within length restrictions.
Recommendation: Brass base pads improve reload performance significantly within division rules.
IPSC Production Division (1911 Variants)
Some Production-legal 1911 variants exist. Check the current approved list and magazine capacity requirements.
Recommendation: Verify your specific pistol and magazine combination meets Production rules before competition.
How to Identify Your Magazine Type
Not sure which magazines you have? Here's how to identify them:
Check for Manufacturer Markings
- Metalform: Look for "Metalform" stamped on the tube or base
- Mec-Gar: Usually marked "Mec-Gar" or "MG" on the tube
- Dawson: "Dawson Precision" marking on base or tube
- Tripp: "Tripp Research" or "Cobra Mag" markings
- Bul Armory: Bul Armory branding or supplied with Bul pistol
Examine the Base Pad Interface
The geometry where the base pad attaches differs between families. If you have an existing base pad, check whether it's designed for Metalform-pattern or Mec-Gar-pattern tubes.
Contact Your Supplier
If you're still unsure, contact the shop where you purchased your magazines or your pistol's manufacturer for confirmation.

FAQ
Which base pad fits my magazines?
Check your magazine manufacturer: Metalform, Dawson, and Tripp magazines use our Metalform/Dawson/Tripp Base Pad. Mec-Gar and Bul Armory magazines use our Mec-Gar/Bul Armory Base Pad.
Can I use 2011 base pads on my 1911 magazines?
No. 2011 magazines have a different tube diameter and base pad interface than 1911 magazines. You must use base pads designed specifically for 1911 tubes.
What's the weight difference between brass and aluminium?
Brass base pads are significantly heavier than aluminium options. This extra weight provides faster, more positive magazine drops—particularly beneficial in competition.
Are these base pads legal for IPSC Classic Division?
Yes. Aftermarket base pads are permitted in Classic Division. Brass base pads provide competitive advantage without compliance issues. Verify overall magazine length meets division requirements.
How many base pads do I need?
Most 1911 competitors run 4-6 magazines in their belt setup plus 1-2 backups. We recommend equipping all your magazines with matching base pads for consistent reload feel.
Do I need special tools for installation?
No special tools required. A flat blade screwdriver or base pad tool is sufficient for most magazines. Installation takes 5-10 minutes per magazine.
Will brass base pads damage my magazines?
No. Brass base pads are designed to work with standard magazine tubes. The brass is softer than steel, so it won't damage your tubes.
How do I maintain brass base pads?
Wipe clean after each match. Brass naturally develops a patina over time that doesn't affect function. Polish with brass cleaner if you prefer a bright finish.
Can I mix different base pad colours?
Yes. Some shooters use different colours to identify magazine capacity or specific uses (match magazines vs practice magazines).
What finish is most durable?
Black finishes tend to show wear less visibly than polished gold or chrome. All finishes are durable and suitable for competition use.
