"Initial review of Extension Kit"

Richard Overall on 1/20/2015 6:52:13 PM

Overall Product Rating:


Bought this with 15-rd mag (P30/VP9). Received promptly. No instructions. Could not figure out how to attach mag upper (base plate and OEM spring w/follower and base removed), no slots to slide in, new long spring wouldn't let it if slots were there. Brain began to rattle and hum, so removed extension sleeve from extension lower, slid OEM mag upper up through sleeve, re-inserted extension spring, then extension lower until it clicked on tabs and voila!: it was done. Will go shoot with it tomorro... More details


"Great addition"

Works great, super simple to install after watching video. Could only get extension to hold 27 rounds of Federal FMJ .40 cal instead of the 28 mentioned (unless they are counting one in the pipe but thats not usually the case). Regardless, quality construction and feeds rounds great.

Adding this to a 15 round P30/VP9 magazine was quick and easy following the instructional video. Easy to load, functions flawlessly in both my p30sk & vp9.

"Great addition to my P30, VP9 worked perfectly"

Garth Oyemeyer on 2/3/2015 12:10:34 AM

Overall Product Rating:


Decided to get a few to test out based on some reviews on Youtube and the various HK forums. The install was a breeze...not sure you need any video to show the average user how to install them but thank you nonetheless. The fit was as tight as one could make them and have them slide over the mag body. I bought them for use on my 9mm VP9 and .40 cal P30. Both fit fine. I was able to get 26 round of .40 in the P30 and 31 rounds in the VP9 with the extension installed. All rounds fed perfectly (jus... More details


"fit all my USPC, VP9 perfectly must have item"

Clarence Woods on 1/29/2015 9:08:51 PM

Bought one to try. Fit all my applications perfectly. 330 rounds fired without issue. Fit was nice and tight. I may have to get more for my just in case stash. Now I need to get the HK45 versions that is in the works and due out soon as I prefer the 45 caliber for my daily carry.
