When I saw the KS-47 Pistol from Palmetto State Armory, I thought to myself “now that looks fun!”. After some hands-on time with this 7.62x29mm pistol, I can say it’s a lot more than just fun! In this article I’ll give an overview of the KS-47 platform, give a guided tour of the 8.5″ pistol (also available as a 16″ carbine), reflect on shooting suppressed, evaluate the trigger, and compare ballistics with my 16″ AK Carbine. Let’s get to it!
KS-47 8.5″ 7.62x39mm Pistol Overview
From the Palmetto State Armory product page:
The Palmetto State Armory KS-47 G2 is based on the AR-15 and combines the modular construction, accuracy, and precision of the AR platform with the stopping power and the magazine options of the AK. The KS-47 G2 lets the AK shooter capitalize on their inventory of AK magazines and AK ammo with an AR-style platform. Unlike the AK, where the barrel is permanently pressed into the receiver, the KS-47 G2 features an AR-style modular configuration which consists of a barreled upper receiver, and a lower receiver that houses the fire control group and magazine. The modular configuration allows customers to have several different barrel configurations with one lower receiver, just by releasing two pins.

TriggerScan Analysis: PSA EPT (Enhanced Polished Trigger)
The KS-47 includes what Palmetto State Armory calls the “EPT” (Enhanced Polished Trigger).
From the Palmetto State Armory EPT product page:
PSA AR15/PA10 Enhanced Polished Trigger
We start with our standard single-stage government-style fire control group, finely polish the contact surfaces and then coat the hammer and trigger in a super slick nickel finish. The result is a trigger that is substantially smoother than mil-spec. A great economical upgrade.
Here’s the KS-47 on the TriggerScan TS-11 trigger profiling instrument:
As I always do, I ran three consecutive TriggerScan passes, and produced the following results:
And here’s the results:
What’s amazing about the EPT is how affordable it is- it’s available as a stand-alone parts kit for around $30.00. Considering how consistently this trigger performs, I’d say that’s a heck of a deal! 5.0 lb peak force is perfect for a run-n-gun type configuration where a medium trigger pull weight is desired.
Test Shooting Scenarios
For shooting scenarios, I decided to focus on reliability, ballistic performance, and suppressed scenarios. Here’s a summary of what I did with the rifle:
- Installed Nikon red dot sight, performed quick sight-in
- Function testing with a few different magazines (Magpul PMAG 10 and PMAG 30, generic steel 30 round AK magazine)
- Function testing with three types of ammunition
- Ballistics testing: KS-47 -vs- 16″ AK carbine
I did not do any accuracy testing as I plan to include this KS-47 in an upcoming series comparing various 7.62x39mm rifles with each other.
The KS-47 functioned 100% with no malfunctions whatsoever. This included three different magazines, three types of ammunition, and three types of ammunition. This also included shooting with the included flash hider, and my SilencerCo Hybrid suppressor. Shooting the KS-47 Suppressed is AWESOME! The form-factor is great, and it’s really nice to hear the steel ring loud compared to the muzzle blast. I’m sold!
Ammunition Tests and Ballistics
For ammunition, I selected three types of factory 7.62x39mm ammunition. I feel these selections cover most common applications for 7.62x39mm.
TUL-AMMO 122 grain FMJ (economy)
I wanted to include some “typical” steel-cased blasting ammo in this testing because that’s why a lot of people like 7.62x39mm rifles: affordable ammo with the “punch” of a 30 caliber projectile.
Federal Power-Shok 123 grain Soft-Point (premium)
I know a lot of people that hunt with 7.62x39mm in various rifle platforms. So I thought it would be a good idea to include some premium hunting ammunition that would be suitable for things like coyote or deer hunting. Federal Power-Shok 123 grain soft point ammunition fits the bill nicely, and has boxer-primed brass cases, so it’s great for reloading as well.
Federal American Eagle 124 grain FMJ (premium)
Federal American Eagle bridges the gap between the TUL-AMMO and Power-Shok ammo I used for testing: this 124 grain FMJ ammo is brass-cased, and has a general-purpose 124 grain projectile.
For each type of ammo, I shot 5-shots through the KS-47, and 5 shots through my 16″ N-PAP AK style carbine. I used my Caldwell G2 Chronograph to collect velocity data for each test string. Here’s the roll-up data from these tests:
What’s interesting here is how the 8.5″ barrel in the KS-47 attained an average of 92.65% of the velocity produced by the 16″ AK Carbine. That’s closer than I would have thought. And that means that this pistol is more practical ballistically than most people would think.
And here’s the data visualized as a bar chart:
I have taken a liking to my KS-47 8.5″ AR-Hybrid 7.62x39mm pistol. It’s compact, powerful, and a great balance between fun and practicality. Here’s some pros and cons:
- Price: ~$700 for a rifle like this is a deal
- Compact form-factor
- Near-carbine ballistic performance
- AK magazine compatibility
- Value: great quality and features at this price-point
- PSA EPT Trigger
- SBA-3 brace, versatility
- Proprietary upper and lower
- No magazine catch (personal preference)
- Not compatible with one-piece drop-in triggers (see PSA product page for more details)
- Not compatible with all AK magazines (see PSA product page for more details)
