[QUOTE="inactive, post: 1260596, member: 7488"] But I recon that the lower sectional density and mass mean that the velocity peters out and penetration is less than a larger bullet with an equal loading. [U][url]http://www.hipowersandhandguns.com/LowPenetration.htm[/url][/U] EDIT: And to keep this related to the original post, I would stick to the .40, due to the fact you can load a larger and higher grain projectile in it. The 180 gr 40 has a higher sectional density than a 125 gr 9mm projectile (.161 versus .141). Even with the added velocity, the .40 usually rates better for penetration in ballistic gelatin. Not to mention any bone, etc (see LDP's post quoting the medical examiner). That, and the cost is far more attractive. [/QUOTE]
