Yes yes yes and yes! I use 3F for pan just because I'll be honest I don't feel like carrying more stuff. I clean everything after each shot. I honestly believe it's how this gun shoots, my .40 is instant BUT it has a nice vent liner. This gun doesn't have a vent liner just a straight hole like the origionals and seems to have a lot of metal in between the pan and chamber. I always keep it clean and put just a little powder in the whole to try and bridge the gap, i dont fill it but you have to put some it or it just isn't reliable. It's delay is definitely more then the .40 but not by much just enough to throw me off a bit. I don't have the heart to put a liner in it because it's different and I kinda like that ha.
if the gun insists on the ka-boom and not k'rack, there is surely something amiss that begs to be tamed and corrected, sez i! some guns have quirks that need attending to, and we'll have no unruly firearms that do as they please for their masters! hear! hear!
what's the touch hole diameter? perhaps it needs to be a tad opened or has built up wall bp residue crud that needs severe cleaning?
my vent pick is a .040 phosphor-bronze wound piece of guitar string and i push it in good to the chamber powder, and i believe that the pick windings pull out a few of the 3f kernals into the vent hole, at the ready to receive the heat from the pan's explosion.
is the vent coned inside? of not, and you don't wish to drill out for a liner, that also may help.
