If it matters Im 5'10, average size frame but I work out alot so I got pretty big muscles
Paper rolls around inside the printerI don't suggest trying to put aluminum foil or something in if that's what you're thinkingIt COULD print on it, but it's not designed to what so ever.
How do you plan to get metal to bend around the feeders and rollers in your printer?
Between just those two I would definitely choose the carbon steel framed Detective SpecialI am not a fan of aluminum/alloy frames (I have a Beretta Tomcat that has a broken aluminum slide rail - after firing no more than 15 rounds)Although +P rounds are not approved for either by Colt, the Detective Special has not been shown to have problems firing it - unlike the aluminum framed Cobra.
