I got a great buy on a new Ruger single action in .30 carbine around 1986 in Dodge City, KS. It was acceptable as far as accuracy and probably power were concerned but it had a terrible muzzle blast and was really loud.
I sold it to a fellow employee who actually liked it. Probably should have looked at reloads to tame that blast.
My Father who carried a Garand in WWII said everyone wanted a carbine but they were not allowed to have them.
Friend had one and it was louder than my 44 mag!
With “rifle” ammo 30 cals, a great amount of the powder burns out in front of the pistol.
Don’t see any positives with this combo.
I'm going to guess that was because the cartridges used rifle powder, and thus needed a longer barrel to completely burn. Reloading and working out a suitable loading using pistol powder might have tamed the beast.
Try to use the fastest powder you can and it will help the muzzle blast.
