I took a basic firearms class back in the spring to get my CCW and each paritcipant had to go through numerous "action shots" 3 of which you mentioned below.
At the time, I took the class with an M9. It was a very enlightening class and no we did not shoot 5k rounds but did shoot nearly 500 - 489 to be exact. Had one FTF which concluded to be a dud primer as the primer was struck and appeared to be full contact.
I discovered the M9 was doable but not very realistic for trying to pull a full size pistol from under a shirt, jacket, etc. at least for me.
After the class, I ended up purchasing a Kahr PM9, an SA XD9sc, Ruger LCP and this last fall a Beretta PX4sc 9.
I carry the PX4sc about 50% of the time, PM9 20% of the time and the LCP the rest. LCP mostly during the summer due to lighter clothing.
No experience with a revolver though.
Thanks for the thought provoking discussion this will lead to.
