Hi there
Yes - old thread that one .
The PX4 was a top vent and yet had a very open barrel right up to the necessary blockage in the breech .
In slow mo on camera you can see the flash is not coming out the barrel - looks a tad weird .
I sold one only recently on Gunstar and I believe if you scroll back far enough there is another going for @ £190 on there . Chap regular has these and the also rather tasty " mini gap " Glock 26 .
Nice piece the PX looks and feels a lot more solid than most Brunis . I am currently working on a chrome 92FS with matching SAK moderator - purely for looks of course as the gun does not vent down the barrel but looks good .
I am experimenting with reduce power rounds to get the action to work / eject but with a much lower ear friendly BANG !!
Pardon ?
Carl.
