You don't have to be a 1911 fan to enjoy this video.

Cool video MRC.

Sorry to say it, but I have to agree with you on that Josh. (That little quote by John Stuart Mill on the bottom of your signature)

The part that surprised me the most is all the 'gyrations' the loaded round makes as it is stripped from the magazine and the case head slides up the breach face and the rim slides under the extractor.

The best shot is at about 1:10 on the video.

Good video.

Speaking of 1911s, does anyone have any experience with fitting and using an oversized firing pin stop to reduce recoil?  It is something I am hearing about recently and was looking for folks with experience using one themselves.  EGW seems to be the go to one.

Thanks,

The guys shooting the 10mm 1911's do it all the time to keep the slide from opening prematurely on the high pressure loads.

They put in a flat bottom firing pin retainer and then replace the mainspring with a heavier rated weight.  You are actually using the hammer to restrict the slide along with the recoil spring.  This should reduce the felt recoil.

I have never heard of any one doing it just to reduce recoil.  Someone at EGW should be able to help if you explain what you are trying to accomplish.  I am sure if you ask on one of the 1911 forums they will help you.  The 10mm forum has some real sharp guys who love to solve problems.

Good luck.

Thanks MRC,

I am hearing that it helps a lot on the .45ACP as well.  Supposedly, this is how John Moses designed it, but the ordinance folks felt it was too hard to manually operate the slide with the hammer down so they rounded it off.
