very quick trip to the range today just so i could shoot it for the first time. no failures of any kind even though I only shot 20 rounds out of it impressed with the sig romeo 5 nice crisp dot small but easy to see even with the sun shinning on the snow. recoil isn't much at all. the blast can seemed to work well felt no blast at all and the sound wasn't bad. target was only at 25 yards. holes not in the black were sight adjustments. the 2 groups were 5 shots of 55grn armscor and 55 grn pmc(all I had on hand). when I get a nicer day I'll take more time o shoot it some more and get some better groupings farther out.
