I noticed that the Sport model is listed at 4.5" barrel, and the L at 5", but the Tanfoglio website has them listed as pretty much the same (119mm vs 121mm). Looking at the pics on your website, there seems to be a clear difference of about 1cm between them, so I'm guessing the technical data on the T website is out of date Especially since 5" is 127mm, so either it's 121mm OR 5", can't be both
