Well took my Ruger SP101 3 inch .327 FM & my newly acquired Ruger GP100 WC & then my Ruger 10/22 50th anniversary custom Tactical I Tac folding stock. My Ruger GP100 WC Blued have to say very very happy and impressed with this revolver. The fit and finish just so so nice the fitting of the parts there are no lines to be seen the fit is that good. This gun performed really nice it was right on POA/POI at 7-10 yds. I was shooting .38 Special 130 grain fmj's Now my Ruger SP101 another story, getting frustrated keeps shooting to the left. Now this is a 2008 mfg revolver so the rear sight is windage adjustable only. Now to move the POI over to the right do I move the rear sight over to the right ?? The rear sight had been moved more over to the left. I was told plus the gun showed it when I bought it. NIB unfired! But shooting this revolver has been very frustrating. Today was shooting reloads .327 FM 94 grain LSWC with 9.5-10 grains of 2400. I also had a few factory loads the Fed. .327 FM 85 grain JHP and Fed AE 100 grain jsp. Seems with all loads its still shooting to the left??? I moved the rear sight so its more centered with the top strap will have to try it out again not sure what load to use on it?? You know with a .357/.38 Spec. a 158 grain is kind of a standard load for POI/POA scenario etc. Now my Ruger 10/22 Tactical with a folding ATI I Tac stock using CCI MINI Mags got it sighted in with my UTG 3-9x32 Bug Out scope it seemed to work fine. Took a bit of time to get it zeroed in but all worked out. Just not sure what to do with my Ruger SP101 .327 FM!!! But couldn't be happier with the results on the GP100 and my Ruger 10/22!!!
