Actually, I have seen a few velocity tests that show while the short barrel does have some loss of velocity it’s pretty negligible unless you are talking extreme differences like between a 10 in barrel and a 2 in barrel. Differences between 3 and 6 aren’t as prominent.
If you want to shoot .38’s I still would get the .357 because you have the option to shoot both. I like options.[/quote]
Yep, you are correct. Muzzle velocities are directly proportional to barrel length to a large degree. In case you didn’t know,“+P” ammo was created specifically to help with the problem of short barrels. check out the link below. It has links to FBI ballisitics testing plus some really good info on recommended ammo choices for a variety of calibers. Note that most modern handgun calibers perform essentially the same so this serves to dispell any “bro science” of “X” caliber being 10000% more deadly than “X” caliber, but that’s a topic in and of itself.

check this site out. they test with factory guns. they also have ballistics charts for several different muzzle velocities. pistol calibers from .32 to .500 Lindbaugh and rifle calibers from Sniper .223 to .50 Alaskan

38 SPL +P BUFFALO-BARNES LEAD-FREE - 110 gr. BARNES TAC-XP, Short-Barrel, Low-Flash
See the below real world velocities fired from real world revolvers, not extra long laboratory test barrels that give false extra high velocities, that cannot be duplicated in real life. With Buffalo Bore Ammunition, youâ??ll always get real world, useable velocities.
1.1438 fps – Ruger GP 100, 6 inch barrel
2.1287 fps – S&W Model 15, 4 inch barrel
3.1210 fps – S&W Model 66, 3 inch barrel
4.1202 fps – Ruger SP101, 3 inch barrel
5.1149 fps – S&W Model 66, 2.5 inch barrel
6.1119 fps – S&W Model 60, 2 inch barrel
7.1104 fps – S&W Model 340, 2 inch barrel
This load is safe to fire from all 38SPL +P rated and all/any 357 firearms that are in normal operating condition. However, when fired from super light weight alloy J frame revolvers, recoil is stiff. This cartridge is designed so the bullet will not jump crimp when subjected to recoil from firing in super light 12 OZ revolvers, provided you do not subject any cartridge to the recoil of more than six or seven firings
