I'm shooting an M&P40 with Apex DCAEK (5 lb trigger pull, reasonably short reset). I probably have a total of 3000 rounds with this handgun since starting to shoot some 6 months ago. I've started to shoot IDPA and Steel Challenge.
Even at the range during slow fire I find I'm more accurate if I just go to reset between shots: relax trigger finger 'til reset, apply a bit of pressure, refine sight picture, squeeze trigger. I'm not sure of the best approach during competition when engaging targets (steel or paper) that require a significant line-of-sight shift: reset immediately after the final shot on the first target and acquire the second target (I'm on the trigger during this acquisition period) or wait until the gun is "on" the second target and stage the trigger as I'm finalizing the sight picture?
I'm thinking this is a very individual thing and will probably depend on the specific gun/trigger characteristics, but I'd be interested in knowing what other do in these situations.
