Gun Won't Open

Harry Collins · 02-15-2018, 02:45 PM

I was asked to help with a VHE that would double when the back trigger was pulled first. The front trigger pull was 2 lbs and the rear trigger was 4.5 lbs. The sear spring was weak and I fixed that. Both triggers are about 5 lbs now. If the rear tang screw is flush with the tang the gun will not open. If I back off that screw a few turns everything works great. When I received the gun the forward part of the floor plate was a bit proud. Has anyone experienced this? Any suggestions?

Kindest,
Harry

Brad has done some great work for me and very timely.

Harry, with the tang screw tightened home, does the top lever feel like it is not opening to fullest extent of it's travel, but when the screw is loosened (allowing the two tangs to spread, the top lever then feels normal?

This forum brings the best minds to bear on parker issues, history etc, etc. It really is a joy to read. (My apologies from digressing from the origonal question on this thread)

Harry,the chances are you're going to need to put in a shim under the trigger plate tang. One or more pieces of 100 pound paper, or even brass shim stock. Make sure all three trigger plate screws forward of the trigger bow are tight and the plate is flush, before tightenine either tang screw. The stock head is likely softened up with oil, and it's allowing the trigger plate to pinch the bolt, because I don't think the trigger plate is firmly seated.

Thanks Edgar. I all the screws on the trigger plate are indexed. I thought I might loosen them and the plate, tighten the two tang screws, then tighten the floor plate screws and see what happens. If that fails I'll do as you suggest and keep you up to date. Again, thanks for the help.
Kindest,
Harry

I think you may find that this gun has likely been messed with prior my someone else this altering it from its original state. Very rarely will an untouched gun develop issue like this on their own.

The plot thickens. I took the stock off and and the gun worked flawlessly. I put the stock on and I have the same problem with the gun not wanting to open when the triggers are pulled. My next move is to back the screw sleeve in the stock for the top tang screw under the top lever. The top tang screw with the stock on can tighten about 1/8 of a turn more than it should. I have just been indexing it. Any suggestions are welcome. Not often a Parker stumps me. Thank the Good Lord for my VA medications. Without them I would probably be slinging screwdrivers at this point.
Kindest,
Harry
