Recoil spring rate increase.
Firing pin retainer. Put in a non-ramped one. Slows the cycle a bit.
I know many do not approve but I have the poly recoil buffer in this one to keep it from pinning the ears back on the slide stop.....
Thanks for the response CM.
So, concerning the recoil spring, should you be looking for the typical 3 to 6 foot "brass ejection" range with the 10mm that you do with a .45?
And also...just trying to learn here...do the long slide 6" models like the Remington or Kimber offerings help or hurt things, as far as possible increased wear, with the increased mass of the longer slide?
