Fist 2 boxes of ammo through my New SR9 and I might as well have been tossing them by hand. Either I cant shoot, poor ammo or the trigger (hopfully one of the latter). After burning all the blazer ammo I put up a new target at 10 yds, switched ammo to federal 115 FMJ and put 17 rounds in less than 31/2 inches (much happier) While cleaning I decided to do a little polishing as detailed elsewhere in this forum. Easy enough! Have not shot it yet but the trigger is quite a bit smoother but still too heavy for my taste. Maybe a lighter string is in order later on.
