waterboy Posted December 9, 2016 Share Posted December 9, 2016 Just wondering if anyone has tried a KKM barrel in a xdm 5.25 9mm yet and if so, how do you like it? Thanks, Tom Link to comment Share on other sites More sharing options...
missed it by that much Posted December 13, 2016 Share Posted December 13, 2016 Guess I never thought of that mine shoots very good like it is. I've read if you want better to have a gunsmith or yourself if your handy to add material to factory barrel and fit along with recrowning will work wonders Link to comment Share on other sites More sharing options...

waterboy Posted December 14, 2016 Author Share Posted December 14, 2016 Both of mine shoot very good as well. More than good enough for uspsa, but im thinking about trying my hand at Bianchi Cup style shooting and from what i understand you want all the accuracy you can get.

GOF Posted December 14, 2016 Share Posted December 14, 2016 I put a KKM barrel in my S&W CORE to replace the factory ported barrel and make the gun legal for USPSA CO. The KKM has a 1-16 twist. A 1-10 twist is pretty much standard for 9mm. The KKM barrel would not shoot my normal 147 grain/880 fps loads. The 1-16 twist is too slow unless I run them faster than I want. I did find that Bayou 124 TCG bullets shot very well from the KKM, so I use those now. But I have to drive them to 1050 fps (more powder) and the recoil increased. Find out what twist rate KKM has for the barrel you want. Bianchi has ( I think) a 120 PF. You can make that sub-sonic with a 147 and a soft-shooting load, but a 1-16 twist won't stabilize them at 880 fps. The twist rate can make a difference.
