    I am new to this site and this is my first post so if I say something stupid or ask a stupid question please don't bust my chops too hard!! Here goes...

    I have recently done some work to my Beretta 92FS to improve it's accuracy and recoil management. 15lb recoil spring, 16lb hammer spring, INS trigger conversion unit all from Wolff gunsprings. It also has a new Barsto semi drop in barrel (which by the way is a really neat mod.). The issue I am seeing now is the barrel at the muzzel end rubbing on the left side of the slide and the gun will consistantly shoot slightly left of center. My observation is the barrel is just a little sloppy as it moves in the frame guides and the tighter recoil spring is causing the pull to the left. Does anyone have any input as to the remedy of this condition or should I just learn to shoot slightly right to compensate? Note: I would consider going back to the stock spring weight but in the current configuation there is little to no experienced recoil. I really don't want to give that up.

    my beretta is also worn on the left side in front of the barrel also it has around 1200 rds thru . try switching ammo and see what happens ,anything aftermarket always has to be fitted to the gun .remember theres a fine line between being accurate and being reliable. beretta has alot of engineers that figure these thing out thats why somethings are not put in their guns. good luck

    Clearly, if you've "done some work" and the gun is shooting poorer than before, what you've done isn't working. I would suggest putting the original parts back in, and then changing out each part to see if it improves or shoots off to the side as you stated.

    Everybody fancies themselves a gunsmith, but guns are designed with particular "events" in mind as the guns cycle and the shells go in and out of battery. Workmanship can have a great effect on how the gun cycles, as can "design changes" such as changing the springs, etc., which can cause the gun to act differently in your hand. I just spent nearly 10 hours working on a brand new gun that was junk right out of the box, but I've slicked down the slide rails, knocked off all the rough machining, and polished a bunch of the parts that had "sharps" on them that were retarding the slide. If you don't have any experience at it, I wouldn't be altering more than one thing at a time on the gun until I was satisfied it's performance was improving.

    Lots of people think that accurizing a pistol is a simple matter of "taking out the slop" in the slide and barrel, but sometimes the guns are designed to have that in there... and cutting down the clearances actually drives the shooting performance in the wrong direction.

    I don't remember ever hearing anyone complain about the slide performance of the 92FS, but if it's "sticking" or rough, so some smoothing of the slide rails with 1000 grit emery cloth, and a touch of oil. Smoothe action works wonders in performance. Make sure any sliding surfaces are clean and slick, and CLEAN. I bought a Ruger a short time back that must have had 5 pounds of spent powder built up in the trigger area and slide boxed areas. The guy just cleaned the barrel and left the rest of the gun to heal itself.

    Anyway, the short advice is to put back the original parts... then change each part, one at a time until you can tell there is a performance difference. If the recoil spring change does it... stop there. If the other changes you've made aren't working... it might be the fit of the barrel and the mating surfaces that match up to it. Bullets don't just turn left by themselves.

    Isolate the problem, then fix it... you'll like the results better...:D

    I'd contact the MFG of the guide rod spring and see if they will send you out another. I don't think it should be that tight. I've seen even new Beretta's cause strange wear patterns to the barrel. Don't compensate, just bump your rear sight to the left.

    Have you adjusted the sights?
