Great news, with the oem spring and follower I got 100% reliability. 17+1 of 45acp ain't too shabby. Now that was with only 100 rounds of Herter's 230gr ball I picked up at Cabela's. I'll be testing more loads in the weeks to come. I think next on the chopping block is main hammer spring and recoil spring calibration packs from Wolff. I have a great gun I use for USPSA Limited but the Sar is just too much fun to not play with. Competitive in limited division? Absolutely not, but a good starter for people who don't want to throw down on a CZ Tactical Sport? Maybe.
