Tom: You said in part; "Last night I stripped the gun and greased everywhere there was oil "

If you use grease that could increase your failure rate. Oil is what the slide/frame mating surfaces need. The oil on the top round in a magazine can also help. I know it is a pain, but worth trying. It is easier than clearing failures.

I'm also of the belief that only SV ammo should be used in a model 41. Why risk damage by using HV ammo that is less accurate? Someone is going to ask; What oil? My response is any CLP (I like break free) or the old stand by Marvel Mystery Oil. bob
