I herited my HS Olympic ISU .22 short , alloy slide, from my grandpa when he passed thirty years ago. It was quasi- unfired, but I shot (and I shoot) a lot of little ammo on it. Its accuracy at 25 yards is astounding.
Here it wears a vintage set of Herrett's grips I purchased on eBay in USA (I'm Italian and I live there) and I totally refinished.
Of course I have its factory slant grips.
