About 2 weeks ago there was a set of grips like that on the EE, expensive.
I see like that once a while at the gun shows, the only ones I have are the target grips right now, square butt ones
Those are round butt ones, some one has sanded them down.
If you want shooter ones look for some rubber ones, usually about $20-30
P.S. there is a gunsmith/ parts dealer at Castor Alb. that may have the screws, forget the name , it will come to me later, Bruce ?
There is also a shop in Saskatoon that has lots of parts, Saskatoon gun shoppe, I have the # in my ledger if you need it.
