I took out the G-20 today. I fired off 50 rounds of double tap 200 gr wfngc. It cycled them all perfectly. First thing I thought it doesn't kick hard at all. Maybe I could get back on target faster with a 9mm but it is in no way painful or unpleasant to shoot. The only thing that is painful is the hurt in my wallet! Its so much fun I could blast of hundreds in a day! I'm going to have to get the AA 22lr conversion eventualy. I was shooting out doors at cans and stuff I hit a decent amount. It tends to shoot left. I have some UMC ammo on the way. I'll get it to the indoor range soon. I really like this gun! also got my tikka out for the first time. I only shot it at 50 yards but I shot atleast 5 3 shot groups that where just 1 ragged hole I would not even be able to measure it must be like .100. It was shooting like that within 10 shots out of the box. Next week 100 yard indoor range before I turn it on the song dogs. If the dogs get close enough they are going to get the 10mm.
