I have to say... I am more than pleased with my G-44. I have been using an Advantage Arms conversion kit for the last several years and the new Glock is heads and shoulders above it.
I picked the gun up and went through it, cleaned and lubricated it. Took it to the range and shot 150 rounds through it last week. This was an abbreviated session as it was stupid cold and windy. Cleaned the gun again and took it to the range today. I now have 450 rounds through it and have had one fail to fire. Second strike and it went off so that is ammunition failure. No fails to feed or eject.
I haven't shot any lead bullets through it, all have been copper washed or jacketed. I did have to black out the white dot on the front sight in order to obtain a good sight picture. I am planning on replacing it with and Ameriglo like is on all of my carry pistols.
I ended up trying about 10 different .22 loads through it today. I was kind of surprised today as the pistol shot just O.K. with a lot of the standard velocity ammunition that I have had good luck with in the past... 4" or so at 20 yards off of a rest. Mini mags didn't do too bad. But, it seemed the faster the ammunition was that I shot through it, the better it shot. It seems to really like some of the hyper velocity Aquila and C.C.I. Stinger. As a matter of fact, it shot the best with the Stingers. In my experience Stingers have never been known for stellar accuracy. Here is a ten shot group that I shot off of a rest at 20 yards with the Stingers this afternoon. While it will never compete against any of my Mark III's, it wasn't designed for that purpose. I did have the one flyer out at 1:00... my fault or the ammo's, but otherwise that isn't too hateful of a group.
