Does anyone know if you can replace the Axis style firing pin/spring assembly that comes on the model 11 with a model 10 or 12 version. I'm just not getting reliable ignition with this set up. I've done all the headspace checks and insured that I wasnt setting the shoulder back too far on my reloads and all of that. I just want to swap this crappy design assemble for the more reliable type with the sleeve. Please advise. Also if it is possible where is the best place to get the parts? Thanks.
