The title says it all!Would be used for home/car defense.My main concern w/this round is muzzle blast, as I've heard people say it's even loud w/ hearing protection on.So I can't imagine touching one of these of in a car or a bedroom.Recoil is less of an issue,would just like to know what it compares to,as I've heard anywhere from 124gr.+p 9mm all the way up to 10mm.Also,if anyone has any experience w/147gr. 357 loads, I would like to know if they have more or less recoil/muzzle blast than the 115/125gr. loads.The gun I would get for this round would be a glock 31,any comments on this as a launch platform is also appreciated.Thanks in advance...long shot!
