Everybody knows that Inferno Pistols are the coolest weapons in Warhammer 40K, right? If your Space Marines can use them, just do it. If they can’t, you’re playing the wrong army. I’ve got Blood Angels, so I’m safe. But the problem is that there are never enough of them in the kits, so eventually you’ll have to make your own. It’s easy, though, if you have the parts.
First you take a Grav Pistol, because noby uses them, and you have dozens lying around. Cut the barrel off, and do the same thing to a Combi-Melta. It’s gonna be fine. GW nerfed combi weapons in 10th, so there’s no reaason to use them anymore. Glue the combi barrel to the pistol. Almost done.
The OG Inferno Pistol has this little detail on the side, and lucky for us, the combi weapon also does. Carefully cut it off the combi weapon and glue it to either side of your DIY pistol.
I think it looks pretty good! And you can finally have a real hard hitting squad of flyboys with swords and pistols. And it’s thematically correct, too. One last thing.
You can use the barrel from other types of Melta weapons, this here is from an Eradicator that I cut up for other purposes. It’s a bit bigger, but doesn’t look too goofy, actually. Go nuts.
