KJWorks KP-19S CO2 Blowback Airsoft Pistol Field Test Review
In this Field Test Shooting Video I take a look at the KJ Works KP-19S. I’ve reviewed the KP-19 in the past, so this one should perform similarly, but it’s been a while and I wanted to get this one out for a proper range session.
I’ve already done a tabletop / close-up video for the KP-19S covering the specs, features, and up-close details, so if you want the full walk-around and all the technical info, make sure you check that out first.
For today’s session, I focused strictly on performance in the same basic field-test format: velocity testing, then a 10-shot accuracy group at 30 feet, and finally some overall shooting impressions.
Velocity Testing (Chronograph)
For the chronograph test, I ran 0.25g Airsoft BBs (not 0.20g), so expect the readings to come in a bit lower than what many people quote online.
My chronograph also decided to be difficult today, throwing “Error 2” messages and not registering shots consistently, so I had to keep working at it until it finally started giving me some readings.
Once it cooperated, I got five velocity readings:
312 fps, 304 fps, 293 fps, 288 fps, 284 fps:
Average of 296 fps
A couple notes to keep things fair:
If I had started the test with zero shots fired beforehand (the way I normally try to do it to maximize “fresh CO2” performance), the first shots could be a bit higher.
Because this was with 0.25g BBs, if you ran 0.20g BBs, you’d likely see higher numbers, potentially into the low-to-mid 300s depending on conditions.
This model also includes an extended barrel option that can push velocity higher, but I didn’t test it that way because most people run the pistol in its standard configuration (without a long exposed barrel sticking out).
Accuracy Testing (30 Feet)
For the accuracy test, I put a paper target at 30 feet and fired 10 rounds. The nice thing here is that the pistol should lock back on the last shot, so it makes it easy to confirm you’re done without having to count.
Results were excellent for a quick out-of-the-box test:
With the exception of one flyer, everything was within about an inch
The group was well-centered left-to-right
Elevation was also very good without any sight adjustments
There isn’t much you can do for sight adjustment on this one unless you add a laser or optic, but you can tweak elevation slightly via hop-up, depending on your setup.
Final Thoughts
This pistol performed really well for me today.
The KJ Works KP-19S has that 1911-style trigger feel, light, short, and responsive, paired with a snappy blowback that makes it fun to shoot. Velocity was consistent once the chronograph started behaving, and the 30-foot grouping was far better than I expected without any tuning.
Aesthetically, it’s also a great-looking gun: a tactical, modern two-tone style with a double-stack magazine look that gives it that “2011 / hi-cap tactical 1911” vibe. If that’s the style you’re after, the KP-19S is a strong choice.
It should also work with most KJ Works tactical 1911 / double-stack style magazines, so if you already own similar KJ Works pistols, you may be able to mix and match mags. You can also run green gas magazines, but velocity will generally be lower. If you do choose to run the extended / threaded barrel setup, you can hide it with a mock compensator, but it will turn the pistol into a longer, bulkier package. Personally, I prefer it in the standard configuration.
Where to Buy
You can check this pistol out in our Canada Store (and possibly the US Store, depending on availability). I’ll include links where applicable, along with general store links where you can browse airguns, BB guns, airsoft guns, pellet guns, blank guns, and accessories.
