Alright, Im fairly new to pistol shooting and I recently purchased a Glock 17 (gen 3/used) and I cant shoot it for crap.  I get lousy groupings and very inconsistant shots.  The reason Im concerned is I can shoot my buddies glock 19 and put one ragged hole in the center of the paper.  

My Glock 17 has a stock trigger and tritium night sights.  I dont really think the size issue between the 19 and the 17 would lead to the different results.  Right now Im thinking new barrel and big dot sights, not sure if that would help.  Any thoughts

-Check for build up or leading in barrel

-Detail strip and check all parts closely for hairline cracks or loose fit

-If you haven't already, get buddy with G19 shoot your 17 just to make sure it isn't you (sounds like your sure but you never know)

The sights could be off too

do not do anything to the gun- get someone else who is a known good glock shooter to shoot the gun and eliminate the shooter as the problem- this is less likely if you shoot another glock well.

What kind of ammo are you using? One of my 17's will shoot a nice tight group with jacketed bullets, but will spray them everywhere with lead bullets.

Umm....you're not supposed to shoot lead rounds.  Copper jacket = good.  Copper plated = good.  Straight lead = BAD.

Maybe you are like me and just shoot the 19 better than the 17.

Yes you can.  Just don't over do it & clean the barrel well after use.

If you are unsatisfied with your groups now then you are REALLY going to be pissed if you go to big dots.

Its not the groupings Im concerned about....its the inconsistancy between simlar weapons.  I dont shoot to get bulleyes.  I want to big dots because they seem much for effective for defensive shooting.

Surprised no one's said to do some dry firing.  Dry fire (safely, unloaded of course) and watch the front sight to see what it does.  The grip is slightly different on the 17, and it may be throwing you off a bit.

the two similar pistols really do feel different to different people...I have both and prefer the 17 for shooting and the 19 for concealing but also check for sure on the trigger...I just picked up a co workers (not a gun guy) G17 and he told me stock trigger...in dry fire I can't tell much of a difference to my other Glocks but I have shot the NY-2 before...although this new to me (1999 model) feels similar in trigger pull, the reset is much sharper than I have had with any other new Glock with the stock 5.5 lb. trigger  setup...

Shoot from a bench rest. Take out the human factor.  At some point the sights could have been knocked off.

I can't shoot the larger Glocks since the hump placement is farther down. Shots are off,grip in uncomfortable and the sights never align naturally. My G19 and 2 G26s shoot where I point them and the sights are dead on when brought up to eye level. All I ever shot was a buddies G17 for years once in awhile and never liked it. One day I ask to see a G26 and instantly knew I wanted it, got a G19 and realized what I was missing. The grip sizes and hump placements do make a difference. Same reason why I can't stand arched mainspring housings on 1911s.
