Following Rule62's comments, I got the spring assisted fire button for my P67. I didn't know these were available. I think it is a worth while addition to the REO. If you have ever had a sticky fire button, you understand, I hadn't used mine for a while due to that sticking problem. You might consider a peek insert to replace the wood block at the same time, if you like to bathe your P67 like it do.
I didn't find it on the website last week but wrote Rob and ask about it. He invoiced me and sent one out. The install didn't take long, about ten minutes, the innards of the P67 are pretty straight forward. The trickiest part was making certain that the negative "plate" that the positive contact hits is perpendicular to the rear of the REO body after tightening the stainless filler tube. [A very small amount of plumbers putty with a toothpick on the
threads is a good fix for a leaky connection.]
