I don't know much about the 92's, but I doubt it's anything to do with your shooting technique. The way you pull the trigger shouldn't make the gun stovepipe or fail to feed. I've got a Cougar in 45ACP, which is pretty similar to the 92's; and I had some issues when I first bought the pistol like you're talking about. Especially the one where a round goes about halfway up the feed ramp and the slide doesn't have the oomph to shove it the rest of the way up. I think I also had a few stovepipes and whatnot. I bought mine used, but it looked like brand new. (To the extent that the bottom of the slide and feed ramp didn't have wear marks from cycling ammunition.) Anyway, after two or three hundred rounds, it seemed to break in a bit and now I've got probably two or three thousand down the pipe, and I can't remember the last time I had a weapon malfunction of any kind. I was pretty upset with the crappy pistol I bought, and almost sold it, but I'm glad I didn't. I like the ergonomics of the pistol, and it's reliable as hell. Now that's it's all broken in, it's solid as a rock; I'd bet my life on it's reliability. (Which we all have to do with our HD pieces) If you're shooting a new or like-new pistol, with good quality factory ammo, I'd just keep shooting it. Until mine broke in well, I just got in the habit of smacking the back of the slide with my hand, because that would get the #$^@ing slide to go the rest of the way to battery. I wouldn't recommend this, however, since I did get a little forceful once and put a nice little snake bite on the palm of my hand. Slide rails are sharp! Haha.
If you're shooting reloads, you may need to try a little hotter powder charge. (WITHIN THE BOUNDS OF YOUR MANUAL!) If you've rolled your own, and stayed at the low end of the spectrum for powder charge, your rounds might just need a little more howzit to propery cycle the action.
My prescription is this: buy two 100 round boxes of Winchester white box at Sports Authority. Shoot it all, and call me in the morning.

My theory, based on nothing but my own musings, is that the good folks at Beretta make a hell of a fine pistol. It's a little tight out of the box, and needs to get some rounds down range before everything breaks in and loosens up, because they're manufactured to such tight tolerances. At least, that's what I'd like to believe, since I spent a good bit of change on the old girl!
