    Improving accuracy on Glock 19

    I am looking for items to improve the accuracy on the Glock 19. Before we begin let me give a disclaimer....

    - I know that Glocks are designed for "combat accuracy" vs match
    - I know more rounds and practice is the best way to imporve accuracy
    - I am a great shot with a lot of other rifles and handguns as well as this one

    What I am asking is how can i make it even better? I shoot well the the G19, but I want to make it as accurate as possible. I have read about a match grade slide lock that is supposed to help out alot and I am planing on buying one. I also am considering a SS match barrel. Is there anything else I should research to make this gun better?

    Thanks,
    Jeff

    If I was looking to make my G19 (or any of my other Glocks) more accurate this is what I would do:

    - Replace the barrel with either a Lone Wolf, Storm Lake or KKM barrel. I've gotten slightly better accuracy out of my Lone Wolf barrels over the OEM ones. I mentioned this to The Katar and after purchasing a Lone Wolf barrel he noted slightly better accuracy as well.

    - Replace the connector with either a #4.5 OEM or Lone Wolf one.

    - Replace the sights with some good sights like Heinie's or Warrens.

    That's about all I would do but I can't outshoot a stock Glock yet so there isn't any need for me to spend a ton of money or time since I'm not going to gain anything from it.

    How much difference did you notice out of the lone wolf barrel?

    Also, can you direct me to a link for the lone wolf or 4.5 connecter?

    Thanks

    I don't know dude...better is the only way I can describe it. I don't shoot for 1" or 1/2" groups or anything like that so I don't know how to measure it.

    Here's a link to a pretty thorough article on modifying a Glock. Some of these changes are purported to increase accuracy.

    http://www.realguns.com/archives/145.htm (there's a part II link at the bottom of that link as well)

    Some also say that the TR Graham Glock Slide Lock also improves and makes lock up more consistent with the result being a significant accuracy improvement, but I have no experience with this part.

    Disagree on changing out the stock barrel. The hexagonal (or octagonal on .45's) rifling was designed for the inconsistency in bullet shapes and diameters by manufacturers in Europe. If a particular bullet was out of spec, it was in spec once the barrel reformed it before it exited. It's an urban myth that KKM, Lone Wolf, etc. barrels are more accurate. Federal Ammunition uses only Glock barrels to test their handgun ammo. Too many times Glock owners change out the barrel AND trigger then claim more accuracy. Installing a lighter trigger makes it easier for the shooter to follow thru on the trigger pull resulting in a better grouping. My Glocks will produce 3/4" groups at 25 yards all day from a sandbag. OK...here come the arrows...

    So many times shooter want to replace everything (i.e. connector, trigger spring, changing out the trigger housing for one with an overtravel stop, etc.).

    First of all, is this pistol going to be carried for self defense? If so, the most I would recommend is to change the 5# connector to the current 4.5# (used to be called the 3.5# connector until several engineers got into a peeing contest over metric vs. English conversions). This will result in a smoother trigger release. Try this first and work on your trigger technique (i.e. pulling the trigger back in a straight line and maintaining the sights for follow thru).

    If the pistol is for competition only, besides the connector, the striker spring can be replaced with a Wolfe reduced power striker spring which will lower the trigger pull considerably. Beware if you reload and use hard primers such as CCI however. Usually this combination (with practice) results in a good trigger setup. My double taps with a stock connector average .18 to .19 seconds. With a 4.5# connector and reduced striker spring, the time goes down to .15 to .17 seconds. Keep in mind, that fast doubletaps are not an indication of accuracy, just fast synapse to brain activity.

    There are a multitude of competition only trigger parts on the market today and you can spend several hundred dollars on a Glock trigger. No need to do all that, with a lot of practice, the results will be the same! Good luck!

    i would put lightening the trigger on the top of the list. for a COMP gun, for carry i'd leave it be.
    I've heard you can tighten up slide/frame fit by gently squeezing the slide in a vise. this also sounds like an excellent way to ruin a perfectly good slide, so proceed with caution. tight slide/frame fit will also improve your trigger slightly. if you unload your gun and slowly squeeze the trigger you'll notice the slide moves relative to the frame slighty as the trigger parts act on the striker.

    You have a Glock 19--a great duty/service pistol. If you want a match/target/bullseye pistol, then get an appropriate one. Don't try to make your G19 into something it isn't...

    I hate that Glockenstein article.

    The guy who wrote it is just a 1911 fanboy who hates Glocks.

    I dont want a match/target pistol. I just want my G19 to have the maximum performance possible.

    I agree with Doc, no matter what you do to a Glock, it still won't perform near as well as a pistol more designed for accuracy. It's a gun designed to be abused and put rounds on target, down range, not precision shooting.

    Are you able to out shoot the pistol? By this I mean are you able to fire the pistol with the performance that it, and not you, is the limiting factor? I am not doubting you, you could be the the best pistol shot in the world...but you need to ask yourself this.

    If not then your money is best spent on a case of 9mm ammo and perhaps a training class.

    I guess my expectations for a firearm are lower than most. If it works when I pull the trigger I am happy. I am definately the failure mode in the Glock system..

    I shoot well, I just want better. No tack driver, just small, tight groups!

    glock race guns are a legitimate persuit i'd say...
    usually made from a 17L or 34, but no reason you couldn't tune a G19 as well...
    i've put 7k+ through mine and still can't out-shoot it though, but i'm interested...
