Re: Oakland U in Michigan issues hockey pucks for self defense

"Locked from the outside" ---- WTF?? :shock: How can that pass Fire safety rules? -- Surely you MUST be able to unlock classroom doors from the inside? -and thus be able to lock them from the inside as well??--
THAT makes NO sense --- :shock: :shock:

Re: Oakland U in Michigan issues hockey pucks for self defense

Jeeez ... Hockey Pucks .. Seems to me that careful "Situational awareness drills" and safety training would be much more effective. If you hear gunshots, take cover, press alarm buttons .. Start moving pupils to safe rooms .. when there, lock the doors (Which should be strong enough to resist even a...

I completely agree that owning the "host weapon" is extremely restricted in my country, in contrast to the US, no discussion there, the difference is, that we have not EVER known any "freedom to bear arms" That has always been a "priviledge" granted by the government to the citizens.

Re: action noise and suppressor hosts

The principles from "Anechoic chambers" probably won't do much to eliminate the noises from a firearm, unless you shoot inside such a chamber .. The effectiveness of the "cones" in an anechoic chember relies on the wavelength of sound being in the range of the physical size of the cones, ant the con...

I try not to "define" "socialism" as a totalitarian ideology.

H&K did just that with the P7 pistols in 9mm kurz and 9 mm Para They had to add some kind of "fluting" to the inside of the chamber to help the case to stick at the point of highest chamber pressure.

Re: How do integral suppressors work?

Given the configuration of the original Scout barrel, you could probably turn down the front portion of the flutes, up to the short full profile section, then shorten the barrel a bit and thread at the unfluted section. Cutting holes in the front part would effectively shorten the barrel, giving you...
