Since it’s the only weapon already available in the mission editor, I’ve decided to do a quick comparison between it and the MKb 42(H). Here are the results:
Here’s the distance from targets:
Here’s the spread on the closer targets, the Walther variant - the battle pass one, is on the right (both target and silhouette). As you can see, it has noticeably less spread and recoil, both vertical and horizontal:
Here’s the spread on the farther targets. Again, the Walther variant is on the right. Here the differences start to disappear, at least on the targets, but when shooting, it of course still felt like the Walther wariant jumped around less:
I’ve also tried looking for the recoil numbers in the property panel and didn’t find any or didn’t notice them, but I’ve instead found out that it has way less spread than the Haenel variant (the parameter is called gun_spread__maxDeltaAngle):
