The 13 round mag is a game changer. When I got my VP9 I loved it but I just can't conceal a full size that much of the time so I wanted HK to release an SK version sooooo badly, but when they finally did last year I balked because it was basically the grip size of a G19 with the capacity of a G26 that became the size of a G17 with the
10 round pinky extension...it was like a bad joke.
Then I saw the 13/15 round SK magazine announcement and dry fired one at the store again...sold, and ordered the 13 round mags immediately. Then I shot it, a lot...and went all in. The 13 round mag turns it into a slide/barrel/sight radius just a tad longer than a G26, with a G19 size grip that holds an acceptable 13, which is not a bad trade when you get the VP series ergonomics and trigger out of it.
So, I have switched my favorite, go-to, overall preference away from 9mm Glocks (which held that title, unchallenged, since I started shooting in 2005), to the VP9/VP9SK. Thankfully I consolidated on 9mm for the most part so the lack of caliber/cartridge choices isn't a big deal. I still supplement the really small with other guns since these are only double stack, but that was true with the Glocks as well (never even bought a G42/43).
The VP9SK with 13 round mag just feels
right. It points naturally, the trigger is great, and the front sight tracks straight under recoil allowing very fast shooting without risk of the group pushing laterally (ahem, looking at you Glock-left). And when shooting less fast, or slowly, it's a freaking laser beam (within the context of a compact/sub compact factory stock striker pistol with close range defensive sights featuring an oversize front sight, Trij HD). And it shoots perfectly straight with the sights perfectly centered on the slide, no adjustment needed, same as the full size VP9, unlike the G's where I always on every single one had to drift the rear sight to the right to get a center POI.
I carry it with the 13 round mag, and usually a spare flush 10 round (spare goes in pocket, smaller is better)
With G19
In Stealth Gear holster for full size VP9 (fits perfectly). I have 1,670 rounds through this one.
Because two is one and I can't have a primary, go-to carry gun without having a spare (it now wears Trij HD sights too)
