Anyone use a Wisner 2 position safety on a Brno 21? Easy installation? Anything to know?
I haven’t used them on BRNO 21s but I have on multiple 98s.
The Smith has to mill the shroud for proper fit. It definitely isn’t a drop-in piece by any stretch. Timing is important too.
The gentleman I had install mine charged $100 IIRC.
They work very nicely; I like them a lot.
I use them on 3x ZG47. Takes a bit of fettling to get silent yet function. Like them
I put one in my 458 many years ago and prefer it to the three position safety.
