mach1soldier Posted May 17, 2018 Share Posted May 17, 2018 (edited) Looking at bull barrels. Of the three, which do you prefer and why. Prefer from people who have fit them. Not how your custom gun performs. looking for fitment info accuracy nuances of fitting stuff like that. Basically why am I paying way more for SVI versus STI or KKM.

bonglee0507 Posted May 17, 2018 Share Posted May 17, 2018 KKM. Link to comment Share on other sites More sharing options...
Foxj66 Posted May 17, 2018 Share Posted May 17, 2018 KKM worked good for me on both of my guns. normal fitting they weren't bad to do. I think 4-5 thousands off the side of the hood and 10 thousands off the hood length if I am thinking right. I also had to relieve the side for the extractor. Also both starting out with a little bit of springing before full lock up and needed a little work on the muzzle end to lock up. I didn't have to touch the upper lugs to get 45 thousandths lock up. Both ended up using a #2 link on PT frame and slide. Link to comment Share on other sites More sharing options...
bjones6686 Posted May 17, 2018 Share Posted May 17, 2018 SVI cost more and takes longer to get since they usually take 6 weeks to receive if you buy directly from SVI. You will find them in stock sometimes at Speed Shooters. But they come with the chamber cut already and a lot less work fitting them. Both the KKM barrels I bought for my Limited builds required the chamber being cut and the feed ramps being cut to the correct angle to get them to feed properly. Both barrels are equally accurate. Never fir or used a STI barrel. Link to comment Share on other sites More sharing options...
RangerTrace Posted May 17, 2018 Share Posted May 17, 2018 I've been extremely impressed with the KKM barrels in my CKs. Link to comment Share on other sites More sharing options...
AllenM14 Posted May 17, 2018 Share Posted May 17, 2018 I have used several infinity and KKM. I dont have any hands on with STI. I used to learn toward Infinity for everything because they needed a lot less finish work. The chamber mouth is throated, the hood is almost pre cut perfect length and they are finish teamed. Only compliant and it is not really a complaint just something to be aware of. They are a smidge larger outside diameter around the chamber and drag on some slides. Lately I have been doing KKM and just dealing with clambering and thrusting and I think I now prefer them over Infinty once all is said and done. KKM gives excellent accuracy and performance but more work to install. Thus the cost difference Link to comment Share on other sites More sharing options...
tha1000 Posted May 22, 2018 Share Posted May 22, 2018 I have found that my SV barrels run slow, if that matters to you. That is both the AET and traditional barrels... I'd not hesitate to use KKM. Link to comment Share on other sites More sharing options...
tcazes Posted May 23, 2018 Share Posted May 23, 2018 (edited) I run Kkm in my limited and open guns. Couldn't be happier. Steady trucking after thousands and thousands. Edited May 23, 2018 by tcazes Link to comment Share on other sites More sharing options...
CrashDodson Posted May 23, 2018 Share Posted May 23, 2018 Schumann also makes a great barrel but I have heard they have been hard to get recently. I have Schumann in one limited gun and SV in the other. Both run great and almost identical velocities for me. I would stay away from SV AET barrels for 40. I have had a limited gun with KKM in the past and no complaints there either. Link to comment Share on other sites More sharing options...
mach1soldier Posted August 23, 2018 Author Share Posted August 23, 2018 Following up to this. KKM bull barrel was easy to fit. No major issues anywhere and had a solid .045 lug upper engagement. For the money, going to stick with KKM for bull barrels. Link to comment Share on other sites More sharing options...
schaet Posted August 23, 2018 Share Posted August 23, 2018 I always went for Schuemann first, Mostly because of the 1x24 twist. I always had good luck with them, with the KKM's as a second choice. However with the lack of availability when I need them I have been going the KKM way. Fitting them was like any other; patience, a little filing and you're good to go. For the price point and the quality KKM is my new first choice. Link to comment Share on other sites More sharing options...
assaulter Posted August 24, 2018 Share Posted August 24, 2018 I've fit a few kkm's and have been very happy with the results, especially accuracy. I've got a bull barrel on my bench waiting to be fit now. Link to comment Share on other sites More sharing options...
