Is there a size difference?
I may be in the market for a 4013 since it has a 3.5 in barrel, same as my 3913 does (which I like) except in .40 cal, but just realized it may not be the same size. (Slide and receiver dimensions) I'm thinking the 4013 could just be a 4003/6 size pistol with a 3.5 inch barrel, or somewhere in between.
Searches don't turn up much so I'm hoping someone has dimensions or both pistols to compare.
Thanks for any info.
