I have no expierence with this situation. I bought a 38 super barrel that has a “ramp” effect for easier feeding and I never used it because I don’t like the idea of brass showing at chamber. I have been warming up towards a Glock 40 cal or maybe 10mm but I hear of this bulge cartridge situation. Can I get a replacement barrel that will not produce bulges. This would be a paper puncher for me and no defensive application. Accuracy would be of prime importance. Any wisdom for me from expierence?
