Time to draw and fire?
In my younger days back in the 1990's doing a lot of IPSC shooting, I could clear a competetion holster and get a (.45 ACP G21) round on an IPSC target at 7 yards just under 1 second (.96-.98 sec) from a random beep in my timer. It took alot of practice to break the 1 second barrier. Now I can do a CCW holster under a jacket at 1.6 seconds on average from a cold draw. Let me do a few draws and I can get it down to 1.5 seconds. I am 62 now and was in my late 40's then. Over time practice will keep you proficient.
