Reviews & Ratings for DPM H&K VP9SK Compact Telescopic Recoil System — 1 review — Page 1

I have about 500 rounds down range with this recoil spring in my hk vp9 sk. I can attest to its reliablity no matter the spring, although that might be round dependent. For reference i shot 124gr fmj, 147 gr HP, and 124gr +P HP. All rounds cycled as they should and had the slide lock back on all mags everytime with every spring. The recoil impulse was lessened and more controllable. The build quality of the part is great. The sorings are nicely finished. I noticed an odd wiggle when installing but gave it a slight twist to get it to settle into place, no issues. No jams.
