The r9 looks like the *perfect* solution for carry. I want one
but have a question about "slam fire" or "hammer follow" - not really sure what the correct term would be.
I've studied the pictures of the internals and don't see a hammer block. What stops the hammer from setting off the next round when it cycles? Low enough mass or a slow enough return stroke? Geometry of the hammer & slide mating surfaces on the return? Mainspring mate-up & pressure? All of the above?
I'm sure it's safe, judging from all of the fans, but I'm one of those people who needs to know what makes it tick. Any help is appreciated!
