Here's my chronograph results of testing the difference of Buffalobore 158 grain .38 +P out of a 1 7/8" LCR and a Ruger 3" LCR with the same ammo. Since it's exactly the same ammo, it sould give a sound example of velocity loss with high grade ammo out of short barrels.

Ruger 1 7/8 LCR yielded 1024, 1027
Ruger 3" LCRX yielded 1076, 1087

We are talking about 50 fps difference here! So not that much loss in 1 inch.
Now in the 4" Ruger secuirty six, we got 1177 fps with the same load, so 100 fps gain over the 3" and 1237, 1218 out of my brother's 6.5" blackhawk. Now that is screaming for some .38 special load! 530 ME ft. pounds for a .38 special.
