| I have a Glock 21sf and Im not happy with the accuracy. If shot everthing in it from cheap blazer brass to corbon and 10in group at 20 yards is as good as it gets. I installed the 3.5 ghost trigger and it didn't help. Reliability with it has been perfect but I want a gun to be accurate as well. If this was my only pistol I would say it is me but I have a glock 23,XD40 and 1911 and can shoot them all accuratly even with cheap ammo. I also have been shooting handguns for 25 years. Anyone else own this gun and have any accuracy problems or have any ideas that might help? |

I have a g21sf and its the most accurate pistol I own, its also my duty gun and eats anything and everything I put into it.
at 20yards you should be hitting exactly where you want. let someone else shoot the gun from 25yards. I would say, specifically with glocks, that if you are not getting the hits you want, its probably you not the gun. Have you shot another glock at the same range/COF and had different results - all other brands do not come into the equation. |
| Like I said earlier I have a glock 23 and when I'm at the same range I shoot it very well at the same distance and all the same conditions as when shooting the 21sf. It could be me but with all my other pistols I have no problem shooting dead on. Which makes me wonder if its something with the gun. I was able to shoot very well with my glock 23 right out of the box the day I bought it. |

Hell, I shoot my 17 less accurately than I shoot my 23. |
| I don't think most people realize the accuracy most modern handguns are really capable of. When I was in the academy, the firearms instructor had us point our Glocks at 25 yard targets. We held the gun steady without our trigger finger in the trigger well. He came alongside each recruit and pressed the trigger for 5 shots while we held the guns steady on the X. Shockingly, three bullet holes were touching and the other 2 were within an inch at 25 yards. Just goes to prove how much shooter input screws up accurracy. |

I had a gen 3 21 that was a tack driver. Then I had a gen 2 21 that was a dog. Ever consider a KKM barrel? Mine have all been wickedly accurate. Yea I have thought about a kkm or lone wolf barrel. I just hate the idea of buying what in my opinion is one of the top 2 polymer handguns in the world and then having to buy a aftermarket barrel to get the accuracy I expect and get out of my other pistols. The guy that runs the shop where I bought it (who is a diehard glock man) thinks it may be a issue with the barrel and that I should send it back to glock to have them check it out. Another friend said he put a stainless guide rod in his G22 and it improved his groups. I thought about trying that before I send it back to glock. |

So then you'll be able to shoot a 9" group at 20yd.  The stock barrel is plenty accurate. Unless there is some kind of defect that isn't obvious upon inspection (highly unlikely), it's probably you.
You really need to have a skilled Glock shooter try it before you waste a bunch of time and money. Your grip may be to blame. The 23 and 21SF have much different grip profiles. Can you describe your shooting grip? |

operator error, my glock's are plenty accurate at 15yds, what distance are you shooting? 15yds and 20yds sometimes 10 to 15yds with the night sights if I'm at the range when some of the cops are shooting with the lights off. For self defense it is accurate enough. I guess I expect it to be just as accurate if not more accurate than my compact G23 and XD40 which will both shoot alot better than my 21sf at least in my hands anyway. |

Its the singer not the song. Work on your trigger control and your 10MOA flinch.
Get an experienced, solid shooter to test it's accuracy - chances are it's a shooter issue rather than a mechanical accuracy issue. It may be me but I feel that I'm an "experienced,solid shooter". I have been shooting pistols and revolvers for 25 years. The range where I shoot is owned by a retired police officer and I have shot with him, his son(who is on the swat team in the city where I live) and his friend (who is on the narcotics task force in the area) and I can hang with them with my G23. But again it may be somthing with me and the 21sf. Or it could be a issue with the gun. Two months after I bought it I had to send it back to glock because the mag release broke. When I called them to verify that they received it the repair tech told me it would be 3 weeks before he could look at it because they where "covered up". I love glocks but like anything else made by man and machine they have there problems. But again it could be me. I just need to figure out why i can shoot all my other hanguns well but not this one |

My 2nd gen 21 was very in-accurate with my plated hand loads and most factory ammo except for Federal Eagle 230 ball. It shot respectably with that.
Maybe yours is very ammo sensitive like mine was. Another possibility is a bad fit for your hand. I shoot the 19 and 29 better than I shoot the 17 or 21 because they fit my hand so well. With the Glock trigger being less than ideal for target work, ergonomics play a bigger role than they would with a 1911 or revolver. If you get a chance try a Glock 30, might be 'juuuust right'. |
| Even a worn out GI clunker of a mismatched 1911A1 should do better than that with military ball at 20 yards (most will do 6in or so at 25) You may have a gun problem. Glock is, or used to be at least, very good with service. Send it via a dealer (so it won't cost you an arm and a leg) to the guys in Smyrna and have them check it over. |
| I own a 21SF. I have yet to have a problem with accuracy. Have you tried moving the sights. Could you possibly be slapping the trigger? Breath control consistent? Sight alignment on target? Try it from a benchrest position and see if it is holding a group. If it is still off I would have someone take a look at it. Hate to say it but there are lemons out there. |

First thing I'd recommend is changing the sights. Those huge Glock factory sights are tough at long range. The second thing is "are you used to the Glock trigger?" They are different than other guns. If you have covered those bases then I would say maybe that gun is not or you.
A few years back I was running a G22 in IDPA and shooting with the same bunch of people every week. I picked up a G21 and G36 and was running them one night. Someone who knows how well I usually shoot asked " Did you switch guns?" I said I had. Their comment was "Switch back!" For whatever reason, I never shot the 21 as good as I could the 22 or now the 17. So I just accept that I shoot the G17 better than I do its larger brothers, better then the 1911 and I even spent a year running a Beretta 92 which is a good gun but the G17/22 shoots like it was made for me. Now I still shoot the others for fun, but when it comes to carry and competition, I go with what works best for me. |
| I rarely say this but if you can shoot say a 4 inch group or less at the same distance with other guns but can't get the 21sf to group better than 10 inches it is the gun! no gun especially a combat auto should be that ammo sensitive that it will only shoot well with one brand or type of amo. 10 inches at 20 yards is NO WHERE NEAR acceptable even for a combat auto. The continuing opinion of those that have been in actual gunfights is you gun's accuracy is a lot more important than people think- since in a fight your ability to deliver optimal accuracy suffers greatly starting with a much more inherently accurate gun gives you a bigger margin for error so to speak |

Now I still shoot the others for fun, but when it comes to carry and competition, I go with what works best for me. I had a glock armorer take of the factory sights and install the Meprolight green dot night sights. The trigger came from the factory with what seemed like a 10lb pull so I had him put in the ghost 3.5lb connecter. The trigger pull is alot better and the new sights did help a little. I would say I'm used to the glock trigger. I've been shooting my 23 for 5 years and I've shot my brotherinlaws 22 some and my friends 27 and can hit pretty good with them. I've probably done 50 or more dry fires focusing on sqeezing the trigger. Maybe the .40cal glocks were made for me. |
