Description
The Strike Industries Extended Magazine Plate is designed to get more ammo into your VP9 mags without compromising draw speed or handling. It adds five rounds to factory OEM HK magazines, so your standard 15-round mag becomes a 20-round setup. That's a practical upgrade whether you're running high round count training sessions or just want that extra cushion at the range.
The whole assembly uses impact-resistant polymer construction paired with a steel locking plate that clamps everything down securely. The engineers built it with a low drag, no snag design, so the magazine seats and extracts smooth on both open and closed slides. You get the extended length spring, the locking plate, the set screw, and a hex tool to make installation straightforward.
This is designed for the full size VP9 (15 and 17 round mags) but not compatible with the VP9SK or 10-round magazines. If you run a VP9, P30, or P30L with standard factory magazines, this gives you an easy capacity boost that looks cohesive with the gun's existing profile.

Frequently Asked Questions
Will this work on my VP9SK magazines?
No, this plate is not compatible with VP9SK magazines due to differences in spring length and magazine geometry. It's designed specifically for standard VP9, P30, and P30L magazines.
How many total rounds will my magazine hold after installation?
It depends on your starting magazine. A 15-round factory mag becomes 20 rounds, and a 17-round mag becomes 22 rounds. The plate adds five rounds to whatever OEM magazine you're extending.
Do I need tools to install this plate?
You'll need to disassemble the magazine to access the floor plate and spring. A hex tool is included to tighten the set screw, and the manufacturer includes important guidance to avoid overtightening the set screw during installation.
Will a fully loaded extended magazine fit in my holster?
Magazine fit in holsters depends on the holster design. Many duty and combat holsters are designed for standard-length magazines, so you should test with your specific holster before relying on it for carry or duty use.
How durable is the polymer construction?
The plate uses impact-resistant polymer that's proven in competitive and training environments. The steel locking plate reinforces security at the connection point where most wear occurs.
