First Impressions of ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine
The ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine is an ambitious attempt to significantly increase the capacity of the classic 1911 platform. This drum magazine from ProMag boasts a whopping 40-round capacity, promising extended shooting sessions with fewer reloads. The use of a DuPont Zytel based polymer body hints at durability and weight reduction, both of which are desirable qualities in a high-capacity magazine.
My interest was piqued by the need for a magazine solution offering greater round capacity during training exercises and potential competition scenarios. Reloading drills, while crucial, can interrupt the flow of practice. A higher capacity magazine promised a more sustained and efficient training experience.
Upon unboxing, the first thing I noticed was the size; it’s significantly larger than a standard 1911 magazine. The polymer construction felt robust, though noticeably different from the steel magazines I’m accustomed to. The weight, while not excessively heavy, added noticeable heft to the pistol.
Compared to standard 7 or 8-round magazines, this ProMag offering is a game changer in terms of capacity. I considered extended stick magazines but opted for the drum design for a potentially more balanced weight distribution. I chose the drum to minimize the length of the mag protruding from the magwell compared to very long stick mags.
My initial impression was a mix of excitement and cautious optimism. The concept is appealing, but reliability is paramount with any magazine, and especially crucial with one deviating so drastically from the original 1911 design. I was eager to see if it lived up to its potential or if it would become another range novelty.
Real-World Testing: Putting ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine to the Test
First Use Experience
My first test of the ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine was at an outdoor shooting range. The weather was mild and dry, providing ideal conditions for testing. I loaded the magazine with 40 rounds of standard 230-grain .45 ACP FMJ ammunition.
The initial loading process was a bit stiff, requiring considerable effort to fully compress the spring and load the last few rounds. Once loaded and inserted into my 1911, the pistol felt noticeably heavier and slightly unbalanced. The first few rounds fired without issue, but by the fifth round, I experienced a failure to feed.
Extended Use & Reliability
After several weeks and approximately 500 rounds fired, the ProMag magazine’s reliability remained inconsistent. While it would often run through 10-20 rounds without issue, failures to feed became increasingly common as the magazine emptied. The polymer body showed no significant signs of wear and tear, suggesting decent durability.
Cleaning and maintenance were straightforward, with the polymer body easily wiped down. Disassembling the magazine for thorough cleaning, however, proved to be somewhat challenging. I found the overall experience less reliable than with traditional steel magazines.
Breaking Down the Features of ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine
Specifications
The ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine is designed for the 1911 Government model chambered in .45 ACP. Its primary feature is its impressive 40-round capacity, a significant increase over standard 7 or 8-round magazines. The magazine body is constructed from a DuPont Zytel based polymer, while the follower is injection molded.
The magazine spring is formed from heat-treated chrome silicon wire, designed for longevity and consistent feeding. The drum-style design allows for the increased capacity while maintaining a relatively compact profile compared to some extended stick magazines. These features aim to provide both durability and enhanced firepower.
Performance & Functionality
The ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine‘s performance is a mixed bag. When it functions correctly, the 40-round capacity is undeniably appealing, allowing for extended shooting sessions with fewer interruptions. However, the frequent failures to feed significantly detract from its overall usability.
Its strengths lie in its high capacity and durable polymer construction. The primary weakness is its inconsistent reliability. The magazine falls short of expectations due to its feeding issues.
Design & Ergonomics
The polymer construction contributes to a relatively lightweight design considering its high capacity. The drum-style configuration, while bulky, doesn’t protrude as far as some extended stick magazines, potentially offering a slightly more balanced feel. However, the added weight significantly alters the pistol’s handling characteristics.
There’s a noticeable learning curve associated with loading and handling this magazine. The ergonomic compromises made to achieve the high capacity impact the overall shooting experience.
Durability & Maintenance
The DuPont Zytel based polymer construction seems durable, showing minimal signs of wear even after extensive use. Cleaning the exterior is easy. Disassembling the magazine for more in-depth cleaning proves to be a bit difficult.
Proper maintenance, including regular cleaning and lubrication, is crucial to maximize the magazine’s lifespan and potentially improve its reliability. The magazine appears durable, but consistent performance relies on proper care.
Accessories and Customization Options
The ProMag Polymer 1911 Government Model .45 ACP 40-Round Pistol Magazine does not come with any included accessories. Customization is limited, as it is primarily a self-contained unit. It’s designed as a high-capacity magazine option rather than a platform for further modification.
While it’s compatible with any 1911 Government model chambered in .45 ACP, its reliability issues may limit its appeal for serious shooters who rely on consistent performance. Compatibility with aftermarket 1911 parts doesn’t really apply to the magazine itself.
