donmarkey Posted September 30, 2006 Report Share Posted September 30, 2006 Anyone have any experience with converting 1917 to cock on open? I was of using one of Ed Lupour's safeties. I'd just like to get a little more info on the subject first. -Don Link to comment Share on other sites More sharing options...
z1r Posted September 30, 2006 Report Share Posted September 30, 2006 No first hand experience but I bet Ed would be able to help you. He's a first class guy. I know Burgess does them. I've just never enquired abut them. By the way, package arrived safe & sound. Thanks! Link to comment Share on other sites More sharing options...

I know Jim Wisner did a article some time back on enfields, I'll have to ask him for a copy. -Don Link to comment Share on other sites More sharing options...
mad_jack Posted October 1, 2006 Report Share Posted October 1, 2006 Shouldn't be much diffrent than the small ring mauser conversion. My first one took me about 2.5 hours, now after 4-5 more I've done I can do them in about an hour. Link to comment Share on other sites More sharing options...

Is there any downfall to shortening the firing pin's travel? -Don Link to comment Share on other sites More sharing options...

All the instructions come with the cock on open kit. Link to comment Share on other sites More sharing options...
karlunity Posted October 7, 2006 Report Share Posted October 7, 2006 Yes. Don't do it. GPC has a part which will allow to the convert to "Cock on opening" problem is there is not enough force left in the firing pin spring to guarantee firing. Click...UH...bad. Unless you have a "oldtime" smith who knows how to reshape the bolt..don't go there. karl Link to comment Share on other sites More sharing options...
z1r Posted October 7, 2006 Report Share Posted October 7, 2006 The deal is, you shorten the drop so to compensate you have to use a stiffer spring. This makes for hard bolt lift and wears the new notch rather quickly. This at least on the COC mausers. The Enfield may be diffrent, I haven't studied up on it but it is routinely done on all the ones converted to big boomers and the Rem 30 which was nothing more than a P-17 was COO. I think the key is in how you well do it and possibly who's methods/kit you use. Link to comment Share on other sites More sharing options...
donmarkey Posted October 7, 2006 Author Report Share Posted October 7, 2006 I've heard that about the gpc kits. Ed's safety reduces pin travel to .200" and uses a 24lb spring. You have to alter the cocking cam but no welding is required. It comes with a new cocking piece. I've heard nothing but good things about his products, so I think I'll try one. Of course the safety costs about twice what I paid for the original gun. -Don Link to comment Share on other sites More sharing options...
