I just purchased a 460 Rowland conversion for a 1911 from his company.
I have three Bullseye guns which are all old and from his father's time at the shop.
A 22 LR High Standard, a Colt 1911 38 Super converted to 38 Special, and a Colt 1911 Heavy Slide in 45 ACP.
The 38 Special is the nicest shooting auto loader I own. I have never had anyone I let shoot it that did not ask if it was for sale.
