but I also learned in those forums from people like (1911 Tuner) how to
tune and reduce the excessive wear on a 1911 by reconfiguring the 1911 to the
original JMB system that consisted of a small radius FPS bottom and using a
combination of a 16# action spring and a 23# main spring, which would produce
two major benefits, 1) was minimize excessive battering to my 1911, which made
me feel better considering what the forums had warned against concerning the
inferior MIM internals, and 2) this system would reduce the muzzle flip. And
3) in combination I resurfaced the hammer face to attain full contact with
FPS. Which achieving a full resistance and delayed affect
I recently pick up a PT1911 and have around 150 rounds thru it and its been awesome. Can you explain a little more on the JMB system? and what is FPS?
Pular, if you look at your Firing pin stop (FPS) you will notice that it has a rounder bottom which makes it easier to cock the hammer, and the stock main spring the Taurus comes with is 19# thats a light resistance also your Recoil stock spring is 18#.
The original FPS was almost square just a slight bevel on the bottom until the army changed it in 1927 so as to make it simpler for the mounted troops to rack the slide, and the main spring was 23# which made the cocking of the hammer allot stiffer. Now theres a misconception that the heavier recoil spring slows your slide down, which it does but the function of the spring is reversed it's there to return your slide to battery and load a fresh round.
So let me illustrate, if you push a door open by the latch side there's hardly no resistance but if you try to push it open pushing on the hinge side it will be allot harder to open. thats the same way the square FPS works when it's rounded it's like pushing it open toward the latch side but when you use the square FPS it's like pushing on the hinge side. Then add a spring loaded door lets say at 19# and change it to 23# and now you have even more resistance.
Now take in consideration that force momentum of your slide only happen at the very first 1/10 of an inch, then you can conclude that everything slows down decreasing the excessive battering to your barrel lugs and slide stop pin because now it doesn't just slow the slide back movement but also slows the return by changing the recoil spring to the original 16#.
You can buy the oversize FPS from EGW and the springs from Wolf.
