I took this to the indoor range the day after I bought it. I had done a quick cleaning the night I brought it home. It really was pretty clean. I shot 30 rds of perfecta 115gr fmj's thru it and I had several fail to fire's. This gun is a SA/DA but even so, several rds just didn't strike and I had to eject them. I bought a box of federal white box 115gr fmj's from the range and they seemed to fire much more reliably. Still had 2 ftf's out of 50. Cleaned the gun thoroughly, including the firing pin channel. Took it out today, and put 22 rds of perfecta through it with not one hitch. That's all I brought with me, and we are leaving out of town today (Vegas Baby) so thats all my wife would let me do. Lol. But, It seems like a good cleaning was all that was required. Great little Pistol.
