Howdy. I'm sorry I didn't get a chance to check the for sale thread until now or I would have replied sooner.
Yes, the holster is actually made for a 4 & 5/8" single action revolver of the common Colt .45 variety. A Ruger Vicaro is exactly what it's made for. It's made to fit the classic 1873 Peacemaker that the Vicaro is a replica of, and this particular one is made specifically for 4 &5/8th" barrels.
You can email me or PM me directly if there are any other questions you might have, or if you'd like to take it. Thanks.
I'm not set in stone on the price, so yes, I'm considering reasonable offers. I guess the operative word would be "reasonable". You can see in the pics the vendor had $75 on it who in turn gave me 20% off. So I priced it to break even after shipping and paypal fees. But I would like to see it go to a new home where it'll get used. What were you thinking? :dunno:
