Thank you for posting that. I never like to base anything not firmly founded in facts. However I already knew the gun was unsafe my watching it fire. Here is the cropped section of page 5 from the owners instructions. Yes, it indubitably says serious injury or death can occur, and I didn't know this but the risk of the degas screw is another added design flaw if it does pose that much of a risk.Just because something can fire successfully doesn't mean it should be brought to the market. I think the idea of a regulated gun was some what cool for Umarex to attempt, but most likely over the 4 years it took them to try and fix this problem gun up they didn't (or didn't want to) resolve it with proper engineering. My guess is that it is more of an advertisement rather than a major seller anyway.They will pull it. As for a better magazine fit. No that might make the problem worse. I think the problem is the whole area would have been needed different engineering, probably costing the consumer another 300-500 bucks per unit or something, and Umarex wanted to stick at their price point especially after announcing it a few years previously. Think about that: we are talking about a rifle that was supposed to be released in 2017-2018, right? That is mind boggling. And it is still flawed. Anyway, if you like it and you bought it more power to you. Just be careful especially letting someone else shoot it.
I found some of the same warnings mentioned above and attached them. They even include a arrow pointing illustration of the problem area.I also saw, interestingly, that you have to only top off with a handpump and can never start out at zero with one. Not that I would ever do that, but it is interesting as well.

I just don't understand why they couldn't go with a conventional tube and valve arrangement for a repeater like AEA. The Hammer may be accurate and powerful, I'm not disputing that, but they took the long way around to get there. I'm not sure I see the advantage of the STTM design with two pressure vessels.

Obviously it could have been shooter differences as it ain't about the platform but about the shooter IMO, but that said, at greater distances it wasn't able to keep pace
Cheaping out will lead to problems. The original hammer prototype had pressure seal on the magazine. A piston type arrangement that would have sealed the magazine to the frame with the shot pressure. High enough force to seal the magazine from both ends. Why did they discarded it is beyond me.Maybe too many parts and complicated machining to make the frame. On the price point must have been a deal killer. Oh you have two "muzzles" to take care of one in the side of the rifle? How do you safely point that thing if there is somebody in the next booth at the range? That statement makes the rifle unsafe to shoot if people are next to you in the firing line. Marko
Patched ball in a black powder is not a very easy task to load either, but kind of fun when you life doesn't depend on it.
The mag post was present earlier. The problem is creating one goes against the modification warning the manufacturer placed, in the instructions, and given the severity of the issue I would be seriously hesitant because that released air will be a built up pressure. What that looks like in implentation I do not know. Perhaps Umarex had a solution such as that but it would have cost another 300 and they were unwilling to do it. I can't speak to either if it is fixable by that method.Loudness yeah doesn't mean much to most big bore guys. Except it is nice to know for those still thinking about it.Another caution I would have is the weight.
