Last week German Chancellor Angela Merkel's government changed its mind on including a ban on paintball in a package of measures it wants to rush through parliament in response to a recent gun rampage.
In March teenager Tim Kretschmer took a gun from his father's bedroom, went to his old school in Winnenden and shot dead nine pupils and three teachers, mostly with expert shots to the head.
The 17-year-old then picked off a bystander outside a nearby psychiatric clinic where he had been due to receive treatment, hijacked a car and shot two people before turning the gun on himself in a shootout with police.
Two months on, a dozen or so young men, and one woman, are limbering up after work in a large hall in northern Berlin to engage in an activity that some politicians across town think may lead to another Winnenden: paintball.
But the sport still remains in some lawmakers' sights because, they say, it "simulates killing", and a review is planned that could still see stricter rules in an already tightly regulated sport.
One can understand the unease of some critics: a sound like a machine gun echoes around Paintgalaxy, Berlin's one and only paintball hall. Some of the names of the country's teams, "W.A.R" for instance, also raise eyebrows.
But in Germany paintballers have to be over 18 to take part, one year older than Kretschmer, so the country's 50,000 regular players were outraged about the proposed ban.
