For those interested, HK433 in Japan's Monthly Gun Professional magazine

[Barn Owl Lover]

In Japanese sadly, but I'll take what I can get until an English language source is able to do such things with the 433 (and even newer 416 variants and even G36s). But there will be photos and charts obviously (though only one preview photo as far as I can find so far--as the mag was just released today). I already ordered my copy and it'll be here (hopefully) in the next week in a half.

I did get my copy of Monthly Gun Professionals magazine with the HK433 as a feature story. Sadly, not much new, given that we've gotten video and photos from Ukraine of the 433 disassembled. However, it's worth noting that the dual ejectors on the Ukrainian 433s seems to be a recent change, given that the Gun Professionals 433 that was disassembled had a single ejector bolt. Of course, the 433s out of Ukraine that have been shown do have the serial numbers obscured in their photos and videos.

I have a feeling that the 433 will never make its way to US Shores. Sig is the main competitor and they have too much market share. Plus All the 416/MR series derivatives would cannibalize its own market share. The only way I could see some viability is to push the 437 in 300 BLK.

IMO at present, HK are selling too many HK416s and G36s, the G36 (which the 433 was meant seemingly to replace) is still in production, and HK overall have mis-managed their marketing for the 433. First, they rushed it into the German Army rifle trials (from what I've been told way too early in it's development cycle), and they kept showing it and marketing it prior to 2022 when it was actually production ready. And even now HK are making tweaks to it (like the dual ejectors on the Ukrainian rifles that weren't there before, or at least before 2023).

Also, the only version of the 433 that has achieved volume sales to this point (unless you count the 20-30 sent to Ukraine for their interior ministry SOF) has been with the 437; a contract for up to 1600-1700 437s for the Schleswig-Holstein police (at least 500 have been delivered in 2024, contract runs though 2026) and the German Army KSK (1000 to be delivered in 2025 as the G39).
