Just ordered a 7 1/2" . 38 Special rifled adapter for .410
shotgun. First time buy from Chaszel. I own Short Lane ones
and their quality is great. From Chaszel site the quality appears equal.
I planned to use my new adapter in my 20 ga. NEF using a Savage .410 adapter, but I'm tempted to buy a single shot .410 for a dedicated .410/.38.
Chaszel has a good website, but after purchase notification leaves a bit to be desired. (No email order verification).
