It sounds like you want a no lock for carry? The cut down/ swap barrel thing would be out for me. The real UDR no lock snub can cost $3000 which would also be out for me I don't know about you. A nice 3" 66 dash 2-4 can be $1000 -1500 & it's not recommended to shoot hot 125 gr very much due to possible forcing cone damage. If you could find a no lock 686 snub that could possibly fill your needs. The 3" ones like a CS-1 us customs gun can go high also. What you decide on is out there if you look hard enough & are willing to pay.
