CANDERSEN Posted October 10, 2014 Share Posted October 10, 2014 I have some gunsmithing abilities for several years I built 9mm 1911's, but always had a real gunsmith fit the barrel. I am into Glocks now and would like to obtain a slightly oversize after market Glock barrel and fit it myself and then see is there is a substantial improvement in accuracy. In fitting an oversize Glock barrel is it simply fitting the top of the barrel to fit into the slide by either shortening the barrel hood or the leading edge of the barrel where it locks up into the slide; and then possible tweaking the chamber depth?

dskinsler83 Posted October 10, 2014 Share Posted October 10, 2014 Generally it's the bottom lug and the hood both Link to comment Share on other sites More sharing options...
DreGarciaTAT2 Posted October 10, 2014 Share Posted October 10, 2014 Generally it's the bottom lug and the hood both What he said. Just make sure you take your time and remove just a touch of material each time. And honestly, my drop in lone wolf and 'super duper holy moly match grade' fitted barrel have less than .25" difference in groupings at 25y.

dskinsler83 Posted October 10, 2014 Share Posted October 10, 2014 I think you would be highly impressed with the Storm Lake Barrel Link to comment Share on other sites More sharing options...
HOGRIDER Posted October 10, 2014 Share Posted October 10, 2014 Installed a BarSto semi-drop in for my G17G4, and only took minor fitting at rear of hood. Great lock up, and accuracy! Link to comment Share on other sites More sharing options...
CANDERSEN Posted October 11, 2014 Author Share Posted October 11, 2014 Was there a substantial gain in accuracy with your Glock 17 Gen 4 over the stock barrel? That kind of where I am now... Link to comment Share on other sites More sharing options...
HOGRIDER Posted October 11, 2014 Share Posted October 11, 2014 Candersen: Some may think the gain wasn't really substantial, but IMO, I was very pleased with the results. Here's a "test" load I was working on @ 25yds off a makeshift rest; first the stock, Glock barrel: And the same load through the Bar Sto: And, trust me the "flyers" were a result of my excitement!

JBP55 Posted October 12, 2014 Share Posted October 12, 2014 (edited) Other than the round you pulled low using the OEM barrel I do not see a great deal of difference in the groups. Good Shooting. Edited October 12, 2014 by JBP55 Link to comment Share on other sites More sharing options...
Torogi Posted October 17, 2014 Share Posted October 17, 2014 I can see it being tighter too, but if it would be a plate, you miked 3 shots on the aftermarket barrel =) I havent repaced mine but I have a KKM ready to be installed. I shoot coated bullets and find them very accurate. Even on the stock barrel. No dirty barrel. No leading so far. Link to comment Share on other sites More sharing options...
daves_not_here Posted October 17, 2014 Share Posted October 17, 2014 I did the drop-in and saw a noticeable improvement. As accurate and reliable as I ever wanted. There was no dickering with something that might be unreliable because it is too-tight. One malfunction could negate all the accuracy gains.
