.38 Spec self defense ammo.?

[ZVP]

I love shooting the hot, light bullet SD AMMO (nonPlus P ammo)through my Model 10 and36!
However is it safe to use in my Cobra .38? The Derringer handles factory 158 gr just fine
I hope this is in the right forum.
Thanks,
ZVP

Whats the worst that can happen? It blows up? The hotter the better

I would go to the company website and see what they say about it or call them.

As long as it's non plus P, bullet weight should not matter about strength of your Colt.
Point of impact in relation to the sights will be different, depending on what Colt made the sight for. Shoot it and adjust accordingly.
