Accurizing a Glock 17

[ap3572001]

If You got a brand new GEN4 G17 and wanted to maximize its mechanical accuracy, where would You start?

I am talking making it able to shoot the smallest possible groups at 25 yards + with PREMIUM FACTORY ammo from a rest.

This is my next project and first one with a Glock.

Send it to Taran Tactical Innovations. www.tarantacticalinnovations.com . You will get the most accurate and reliable Glock possible.

I'd be interested in hearing how your project goes as I've been looking into this for Gen3 and Gen4's for awhile. Hoping you will benchmark accuracy with several different factory loads before you start, or even better, work up a hand load.

ive tried bar sto, lone wolf, Efk, Kkm and factory barrels, barsto is great, Kkm is also good and I've had a lot of good luck with them, perhaps drop a new connector and spring kit into it, I've also has good luck with zevs "competition" package, and it's like $30.
IMO it's not worth sending out to companies for $550+for a stipple job, some polishing/connector and spring work, and some laser engraving. That doesn't exactly make it more accurate, or reliable. It's not like these things are known for their out of box unreliability
It's a glock...
As far as accuracy, they're not bad out of the box..

Aren't you asking a lot? Glocks are mainly self defense type designed pistols. Not really made for precision shooting. Maybe get a good set of aftermarket sights and a ***** load of ammo to start before spending your coin.

I think I get where he's coming from. On a good day, with plenty of light, I can keep 10 rounds standing/freestyle in the black of a B-8 target (5.54") at 25-yards with a stock-barrel G17 Gen3. I'm told that a good Gen4 sample is capable of a smaller group, maybe 50% smaller, so I'd like a smaller group.

There are three reasons I want a smaller group and am willing to spend to get one as long as reliability does not measurably fall off: (1) Active shooter scenarios are becoming more common and a distance shot is more of a possibility. If I'm at one end of a movie theatre when rounds start flying, I don't want my only option to be "close the distance". I expect and train to be able to shoot to the limits of my gun (2) The crowd I train with shoot "standards" to train against and to measure progress. Most of those standards include accuracy at distance. I'm competitive, my friends are competitive, so....within the paradigm of "combat reliable" I also want as accurate a pistol as possible, and finally (3) I'm obsessive and shooting smaller groups with a Glock feeds that.

#2 & #3 are fine and make good/useful range time with friends.

If #1 is actually a reason, you should be training with a Glock 26 or your preferred carry gun and should only consider mods that are 110% reliable. A large % of mods decrease reliability. Realistically, very few people would CCW a highly modified/accurized G17 in a movie theater.

Perfectly fine to do everything you're doing. Just gotta be a little realistic about your active shooter scenarios.

I've been rotating carry of a G26, G19 and M&P 340 for years. The G26 just got replaced with a Shield and I'm thinking about retiring the J-frame and adding a G17. Among other things, I've attended two 40-hour scenario-based LE Active Shooter Response schools, so I think I've got a somewhat realistic understanding of the concept.

Your stock g17 will hit a man size target at 120 yards with bulk ammo.

The gun isn't going to be the reason you missed.

If anything, throw in a - connector, polish job, and better sights (some will say FO/black rear, I vote for tritium, either work better than stock).

Save your money for other gear, training or ammo.

In my experience, my Gen 4 Glocks didn't get as big of an accuracy improvement as my Gen 3's did with KKM drop ins. But there is a noticeable improvement shooting off hand but its slight.

Although I understand the logic behind your reasoning, I'd caution you on modifying your gun to chase a few inches at 25y at the expense of reliability as everything is a trade off.

Personally I'd participate in some IDPA or USPSA matches and when you can shoot 3" groups on all targets in all stages, you can start worrying about increasing the mechanical accuracy.

I just bought a Gen4 G17 so later this month I'll give it the side-by-side 25-yard test. I hope you are wrong, otherwise I'll be kicking myself for not just getting a KKM for my Gen3 I'm going to try the KKM on a G19 though.

I should have also added, to make it more clear, every Gen 4 I've shot has been more accurate than the equivalent Gen 3.

Trigger job and learn to shoot it to its mechanical capability.

Trigger jobs come in all shapes and sizes. If you want to go for pure accuracy then go as light as possible while maintaining reliability. For a Glock, I believe this is 3-3.5 lbs.

I'm not sure I follow-up your logic behind tight group accuracy bench rest with a Glock 17. Doesn't make sense to me but to each his own.

Dry practice. Devote more time and less money.

Look at about 27:10. Taran talks about the factory barrel accuracy. I shoot USPSA and GSSF just use the factory barrel. I run moly coated bullets too.
