Hi Folk's, I was at the LGS yesterday and noticed they had a SP101 that was DAO but had a hammer which I thought at first glance resembled a 1911 commander hammer. On a closer look I had little doubt it was a hammer from a P-series (P90?) Ruger pistol. It didn't look bubba'd & the store owner swore it was factory. Chambering was .38 special. It would not stay cocked but functioned fine otherwise. Any ideas? -Dave
