Product Description
Built for duty, our HK 45 +3 is the big brother to our HK VP9/P30 "Border Special."
Designed at the behest of law enforcement, the Border Special line provides maximum security, strength, and durability on the HK magazine -- and works with the stock spring. Use our HKVP9/40 spring as a replacement when your springs start to wear out.
Mark III version: Built specifically for the HK 45, and no longer works on the HK USP 45 compact. We closed the small (but unsightly) gap between the top of the magazine and the bottom of the frame (needed for the HK USP 45 compact), while retaining the extra length added in the 2.0 model. That extra length made loading the full +3 easier, but still kept the overall size reasonable for a duty gun.
Together, the upgrades make this part flashier, and easier to use.
- Includes anti-vibration screws
- Spring-steel locking plate Cerakoted black for corrosion resistance
- Overall length assembled is approximately 150mm (145mm measured down the back) -- slightly too long for use in USPSA "Limited" competition.
Weight: 1.25 ounces
Material: Aluminum
Color: Black

HK45 +3 mag extension
Not as advertised....first attempt could only get 1 extra round in mag. Had to get on YouTube where I found out you have to modify the follower to make make it work. Second try after modification it worked but could only get 2 rounds safely in the mag. A 3 rd round did not fit with normal reloading pressure. If you somehow got a 3rd extra round in the mag, the mag will not fit in the pistol with a round in the chamber .
