I live in Calif. and own a SV that I bought 14 yrs ago. But I wanted to try a steel frame gun. Bought a Para with the PXT extractor and SA magwell, had a 2 lb. trigger job done on it with tool steel parts and had the mag catch welded at a muffler shop, fitted it myself and using my SV mags. The gun shoots with a stock barrel and bushing easily a 2" or less at 25 yds. 180gr, OAL 1.175 with 4.5 TG.
The deal with the L10 idea is that, would you think here in Calif, there would be alot of shooters doing it and even more so with new guys coming into the sport but its not TRUE!!!!!!
Most make their way into Limited or Open!
Get a Para make the S_I mags work, in case, you do get a S_I, in the future and enjoy the sport.
