I have a 375-408 variant build in progress and some how my order from Stiller never got placed 5 months ago like it should have. Anyway since I have to wait is Stiller the best choice? Any left hand model yet? A couple actions I've been looking at are the Bat, Extreme Machining, And Stiller. Extreme says any action left hand but I will have to call to confirm. Any pros or cons from each?gun)
