I've been a fan of j frames for years and carry one often. The newest (used) one I got is a 640 in .357. Now I've seen the gel tests and all that between .357 and .38. I also understand that the barrel needs to be long enough for a .357 to ignite all of it's powder before it leaves the barrel and that 4 inches is optimum. Here's my question: I usually carry Speer Gold Dots or some other +P .38 ammo in my 640. Is the difference between a .38 +P and .357 that great even if it's a 2.5 in barrel? I have every confidence in my .38 self defense loads, but was wondering if any of you had personal experiences or preferences between the two.

Maybe I should've phrased this differently since I never got an answer. Is there any noticeable difference in recoil? Re-acquiring the target? What are your personal preferences? Are any of you less confident about .38 than you are .357 so you just WILL NOT carry .38?

From what I've read, there is most definitely still a ballistic advantage to .357 Magnum. However, from what I've experienced, I don't know if it's worth the increase in recoil, flash, and shot-shot speed. In a short barreled, and lightweight, revolver I'd probably just carry .38+P; UNLESS I'd shot that gun enough to know I could handle the recoil well enough to keep accuracy and speed up.

Probably the quickest way to tell is if you try and rapid fire it, do you have to constantly readjust your grip?

Have a J frame Model 60, pro Series from S&W performance center with a 3" barrel. I can tell a pretty decent difference in 38+P rounds and .357s. Maybe it is the extra 1/2" on the barrel, but the .357s launch pretty hot and seems to take a bit longer to reacquire the target in rapid fire. That said, I carry Hornady Critical Defense rounds in .357 and feel confident that I can and will use the gun effectively if required. a quick speedloader belt set and 15 rounds available if needed.

I've never put .357s through my 640, only high pressure .38s. I'm pretty confident with the .38s but there's always this little doubt in the back of my mind that MAYBE I should spring for some .357s and start practicing with those again. I've got a little Smith 637 and I've put thousands of rnds through it, some regular but many +p. Mainly, I switched to the heavier 640 because I'm starting to develop arthritis and shooting the 637 became a painful ordeal. That keeps me from really trying out or practicing the .357. But if my hands can handle it and the difference is worth it in a self-defense scenario, I'll definitely switch.
