PAS ignition spearment
CYA friends:
Man, wouldn't it be so cool for our 40-X friends to be able to have PAS ignition........
What would be even cooler, and of more interest to me, would be for me to have PAS ignition for my #14 pistol...
___________________________
Here's what I'm up against:
I've got to be able to drive a 2 ounce TCA firing pin, with 1/2" less firing pin spring room inside of the firing pin...
The 1/2" must come off the rear half of the breech bolt......
By the way, there's absolutely no doubt that PAS ignition can be driven in the 40-X breech bolt.....
__________________________
Anyway, the prudent thing for me to do, before I go to all the trouble to build a PAS, XP breech bolt, is to discover whether I can drive the TCA pin, with 1/2" less spring length....
By the way, even though I have 1/2" less firing pin spring room, I've calculated, that I don't have to shorten the TCA spring a full 1/2"...
More like .430" will have to be removed....
__________________________________________
Below is a picture........
What I'm going to do, is to shorten the spring in my 10-X triple, then see if I can drive the pin properly.....
I've already made up a spacer, and, I'm also going to try an assist spring.....if necessary......
If I can make this new spring system drive the pin, with any sort of moderate bolt lift pressure, on my triple slave.......then on a 90 degree lift XP the bolt lift effort will be a snap...
More later.....
By the way, the first test will be to see if I can duplicate the firing pin penetration depth with the shorter spring(s)...
If I can, the second tests will be to run 10 round penetration tests......( I already know what my slave triple will do, as is)
Your friend, Bill Calfee

By the way, I've not shortened the Pepper spring, or, the assist spring yet.....I'm going to double check my calculations first...
One issue is, the coil spacing is different on these two springs......bc
