    If you are a really good shooter, your groups may be about one inch smaller at 25 yards.

    I have to say that posting on a gun forum to me seems somewhat problematic.
    There are literally thousands of folks reading with an extreme spread of skill and experience with handguns.

    So I can answer questions honestly.
    With actual experiences I've had.
    But even with the best intentions that may not translate.
    Or worse yet even mislead.

    When I think back 20 years ago I bought a S&W 629 44 Mag
    and shot the crap out of it.
    So much I loosened the cylinder and had to have it re-tightened by a gunsmith.
    I could put 6 magnum 240 Hydra shoks in a soft ball sized group.

    Few moths ago I pulled that bad boy out of storage.
    Loaded it up with more magnum 240 Hydra shoks.
    And fired six rounds into a single ragged hole.

    The gun hadn't changed.
    The ammo hadn't changed.
    But I had.

    So can I, today, tell the difference between Glock OEM and Storm Lake barrels?
    You bet.
    Can you?
    Maybe? Maybe not.

    20 years ago I would have spent the money.
    And not been skilled enough to even notice the difference.
    I'm just saying...

    I like the KKM barrels for shooting lead and/or shooting reloads loaded to 1911 OAL. In my very limited experience (sample size of two), the KKM barrels are short-chambered and one needs to use a finish reamer.

    I plan to get a KKM barrel for my incoming G35 so I can shoot the same reloads I use in my SV Limited gun. KKM can make an accurate barrel as the barrel in my Sams 9x19 PPC gun is a KKM and that gun shoots 1.47" ten-shot groups at fifty yards from the Ransom rest. Barrel fit is key for accuracy. For best accuracy, I would not use a drop-in barrel.

    Bar-Sto also offers an excellent (accurate and good feeding) Glock barrel based on a shooting buddy's experience.

    I have KKM barrels in both my G19 and G34. I am very happy with them. My groups tightened up a bit with both pistols, not by huge amounts but it was noticeable. The main reason I got them was to shoot lead reloads, however as mentioned in the post above they have tight chambers. If you reload you should check your rounds in the KKM barrel, I had to seat my rounds a little deeper to get them to chamber properly.:wavey:

    KKM barrels are great.

    I dropped a KKM in my Glock 24c. I had to ditch the factory ported barrel so I could use it in the limited division. The KKM dropped right in, no modification was needed, no trimming the hood. And it fit up tight, just a little tighter than the factory barrel. I didn't notice any real difference in accuracy myself, but I never benched the gun. All I know is I didn't have any problems, the gun functioned reliable, and its still more accurate than I'm capable of shooting.

    If your going to go all the way, just get a bar-sto barrel. Don't get a KKM unless you just need it for lead bullets and more chamber support, and don't have the budget for a bar-sto.

    I only have experience with the KKM 10mm barrels, but from what I have seen, they are top notch quality. The lockup is much tighter than an OE barrel and it has much better chamber support. A handgun is a handgun, IMO, so talking about accuracy between the two is futile. I believe a shooter would benefit from their barrels if they are experiencing case bulging from hot hand-loads and/or want to shoot cast bullets. For the price difference between KKM and Lone Wolf (which I also have experience with), I think the KKM is a much better buy. The overall fit and finish is better than I have seen on other aftermarket barrels. They also come with a polished feed ramp, which saves the user some time.

    check out my review with the G19 and KKM v.s OEM. I also include some pictures in the review. Do a search and you will find it. Also include a MGSL for wonders.
