Yes, it is very similar to the conversions done by Jovino. I'm sure many more will chime in shortly, but Austin was one of our nations pre-eminent pistolsmiths & one of his specialties was cutting down concealment weapons for pros (mainly Browning HPs, 1911s & N frames like yours). He passed a few years back. He was a master gunsmith & a true gentleman. You own a valuable heirloom, sir.
