Strike SIEMPMPS S&W M&P 9mm/40 Smith & Wesson (S&W) Magazine Extention Polymer Black Finish Review

First Thoughts on the Strike SIEMPMPS S&W M&P 9mm/40 Smith & Wesson (S&W) Magazine Extention Polymer Black Finish

As an experienced outdoor and tactical gear specialist, I’ve seen countless accessories come and go. But there’s always a need for reliable and affordable upgrades, especially when it comes to firearms. That’s where the Strike SIEMPMPS S&W M&P 9mm/40 Smith & Wesson (S&W) Magazine Extention Polymer Black Finish comes in, promising enhanced capacity and improved ergonomics for the popular M&P Shield.

I was consistently finding myself short on rounds at the range with my Shield, and the standard magazine capacity felt limiting during tactical drills. The lure of a few extra rounds in a compact package was too strong to resist. I was particularly interested in how well the Strike extension would blend with the existing ergonomics and texture of the Shield.

Upon unboxing, the Strike SIEMPMPS extension feels lightweight but sturdy, thanks to the polymer construction. The black finish seamlessly matches the factory magazine, providing a clean look. It’s far lighter than metal alternatives, which is crucial for maintaining a balanced feel in a concealed carry setup.

I considered options from other manufacturers like Pearce Grips, but the Strike Industries offering stood out because of its advertised seamless integration and claimed ergonomic enhancements. Many extensions on the market add bulk and ruin the slim profile of the Shield, something I was keen to avoid. My first impression was cautiously optimistic; it looked like it would deliver on its promises.

Real-World Testing: Putting Strike SIEMPMPS S&W M&P 9mm/40 Smith & Wesson (S&W) Magazine Extention Polymer Black Finish to the Test

First Use Experience

My first outing with the Strike SIEMPMPS was at my local outdoor shooting range. I tested it with both my 9mm and .40 S&W Shield pistols. Installation was simple, requiring only basic disassembly of the magazine baseplate.

Performance was surprisingly consistent. The added grip length provided a more secure and comfortable hold, especially with the .40 Shield, which tends to have snappier recoil. I did experience one failure to feed in the 9mm Shield within the first 50 rounds, which I chalked up to the new spring settling in.

Extended Use & Reliability

After several range sessions spanning a couple of months, the Strike SIEMPMPS has proven itself to be reliable. I’ve put approximately 500 rounds through each Shield (9mm and .40 S&W) with the extension installed. The failure to feed issue I initially experienced with the 9mm Shield has not recurred.

There are minimal signs of wear and tear. The polymer has held up well to repeated magazine changes and general handling. Cleaning is a breeze; a quick wipe down with a damp cloth is all it needs.

Compared to my previous experience with the stock magazines, the Strike extension significantly improves grip and control, especially during rapid fire drills. It definitely outperforms the standard magazines in terms of ergonomics and capacity. The added rounds and improved grip profile make a noticeable difference.
