I think they discuss dwell time in this video.
If the barrel drops immediately as the slide move back in a browning locked breech design, the unlocking part happens BEFORE the bullet exits - which of course is not good for accuracy. If it travels further and out of the barrel PRIOR to the barrel dropping AND the lockup is solid, that is optimum.
If you pull the slide back on a gun, you can get a hint at the dwell time. Do this on a CZ P07/09 and see how long it goes BEFORE the barrel drops. Long dwell = more stability.
IF you pick up a MP9 it seems to drop almost immediately. Are their engineers stupid? You decide.
That was an excellent video. Thanks for the link.
Roger - NP. "Match Grade" drop in barrels generally don't do this - unless they say so - Apex does.
I kept my 1.9 M&P, added night sights, the Apex duty/carry kit, Apex aluminum trigger and Apex sear reset thingy. The gun shoots well and is more accurate than me. The only other thing I might do is add a threaded barrel and comp. Faxon had theirs on a Black Friday sale last year and I was tempted but didn’t.
