Am reposting this in it's own thread in hopes of suggestions/advice. Have a 21SF Gen 3, and really enjoy it. It does, however, shoot slightly to the right unless there's a death grip on it with my support hand. At first I simply attributed this to me, the shooter, especially since this is the first Glock I've purchased and didn't have anything to compare it to. Later, shot a G30SF rental as part of my research for a CCW. It was dead-on target every single time, even filthy dirty (it looked as if it hadn't been cleaned in weeks). So, started doing dry fire drills on the 21SF and realized that at the moment of trigger break, the muzzle wavers ever so slightly to the right, consistent with results seen at the range. The front sight begins to touch the right side of the rear sight posts, but that's as far as it goes. Took advice of previous posts on forum and put a snap cap on the slide next to the front sight. When dry firing, the snap cap on the slide slides towards the right, but it does not fall off or fall over. Bought a Gen 3 30SF this week, shot it this weekend and it is just as dead-on accurate as the rental I shot months ago. Dry fired it, and the sights do not move at all upon trigger break, consistent with range results. A snap cap on the slide remains perfectly still when dry firing. Because of this, I'm inclined to think that the 21's trigger could use smoothing out, but have absolutely no idea what is needed. Would really appreciate input from folks here who might have suggestions as to what might help make the trigger break more smoothly and eliminate that little wobble. I am not a gunsmith, nor am I interested in trying to pretend being one. All I'm asking is if this is a simple fix that I can do (like give a part or two a good rub down or lube or something requiring no machining, sanding, or replacement parts), or is it something that I should contact Glock about directly to see if they can do something with it for me? Thanks.
